&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object that is being replaced.&lt;/span&gt;&lt;/li&gt;

&lt;tr&gt;
&lt;td&gt;This issue has been resolved in an Appian hotfix/new Appian version. Please apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;h2&gt;&lt;span&gt;Symptoms&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Following an upgrade of Appian, some&amp;nbsp;&lt;a href="https://docs.appian.com/suite/help/latest/Connected_System_Object.html"&gt;Connected System&lt;/a&gt; objects fail to load with the&amp;nbsp;following error message:&lt;/span&gt;&lt;/p&gt;

&lt;h2&gt;&lt;span&gt;Cause&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;This behavior&amp;nbsp;occurs when an Appian Application&amp;nbsp;has the same name as a Connected System object. This issue has been addressed via&amp;nbsp;&lt;strong&gt;AN-145648&lt;/strong&gt;&amp;nbsp;in&amp;nbsp;the following hotfixes/versions:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;

&lt;/ul&gt;
&lt;p&gt;If&amp;nbsp;a hotfix is required for Appian 17.4 or 18.1,&amp;nbsp;open a&amp;nbsp;case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/span&gt;&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object that is being replaced.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected System object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click on the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes.&amp;quot; Further steps will depend on installation type:&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that behavior in line with this article is present. Ensure to confirm on the support case that&amp;nbsp;the above steps for the second workaround option have been completed.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to the&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf&lt;/code&gt;:

&lt;h2&gt;&lt;span&gt;Cause&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;This behavior&amp;nbsp;occurs when an Appian Application&amp;nbsp;has the same name as a Connected System object. This issue has been addressed via&amp;nbsp;&lt;strong&gt;AN-145648&lt;/strong&gt;&amp;nbsp;in&amp;nbsp;the following hotfixes/versions:&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;

&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;

&lt;/ul&gt;
&lt;p&gt;If&amp;nbsp;a hotfix is required for Appian 17.4 or 18.1,&amp;nbsp;open a&amp;nbsp;case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/span&gt;&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected System object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click on the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes.&amp;quot; Further steps will depend on your installation type:&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that you are experiencing&amp;nbsp;behavior in line with this article. Ensure to confirm on the support case that you have performed the above steps for the second workaround option.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to the&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&lt;tt&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf:&lt;/tt&gt;&lt;/code&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;Restart the application server.&lt;/li&gt;
&lt;li&gt;Once the environment is accessible again, you can remove the above added line from the &lt;strong&gt;custom.properties&lt;/strong&gt; file.&lt;/li&gt;
&lt;/ol&gt;

&lt;/ul&gt;
&lt;p&gt;If&amp;nbsp;a hotfix is required for Appian 17.4 or 18.1,&amp;nbsp;open a&amp;nbsp;case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/span&gt;&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected System object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click on the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes.&amp;quot; Further steps will depend on your installation type:&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that you are experiencing&amp;nbsp;behavior in line with this article. Ensure to confirm on the support case that you have performed the above steps for the second workaround option.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to the&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&lt;tt&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf:&lt;/tt&gt;&lt;/code&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;Restart the application server.&lt;/li&gt;
&lt;li&gt;Once the environment is accessible again, you can remove the above added line from the &lt;strong&gt;custom.properties&lt;/strong&gt; file.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;&lt;span&gt;Affected Versions&lt;/span&gt;&lt;/h2&gt;

&lt;/ul&gt;
&lt;p&gt;If you require a hotfix for Appian 17.4 - 18.1, please open a support case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/span&gt;&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected System object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click on the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes.&amp;quot; Further steps will depend on your installation type:&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that you are experiencing&amp;nbsp;behavior in line with this article. Ensure to confirm on the support case that you have performed the above steps for the second workaround option.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to the&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&lt;tt&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf:&lt;/tt&gt;&lt;/code&gt;
&lt;div class="content-scrollable-wrapper"&gt;
&lt;pre class="code-java"&gt;conf.suite.RERUN_CS_ENCRYPTION_MIGRATION=&lt;span class="code-keyword"&gt;true&lt;/span&gt;&lt;/pre&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;Restart the application server.&lt;/li&gt;
&lt;li&gt;Once the environment is accessible again, you can remove the above added line from the &lt;strong&gt;custom.properties&lt;/strong&gt; file.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;&lt;span&gt;Affected Versions&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;This article applies to all versions of Appian from Appian 17.4 to Appian 19.4.&lt;/span&gt;&lt;/p&gt;

&lt;/ul&gt;
&lt;p&gt;If you require a hotfix for Appian 17.4 - 18.1, please open a support case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;

&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected Systems object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes.&amp;quot;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that you are experiencing&amp;nbsp;behavior in line with this article. Ensure to confirm on the support case that you have performed the above steps for the second workaround option.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&lt;tt&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf:&lt;/tt&gt;&lt;/code&gt;
&lt;div class="content-scrollable-wrapper"&gt;
&lt;pre class="code-java"&gt;conf.suite.RERUN_CS_ENCRYPTION_MIGRATION=&lt;span class="code-keyword"&gt;true&lt;/span&gt;&lt;/pre&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;Restart the application server.&lt;/li&gt;
&lt;li&gt;Once the environment is accessible again, you can remove the above added line from the &lt;strong&gt;custom.properties&lt;/strong&gt; file.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;&lt;span&gt;Affected Versions&lt;/span&gt;&lt;/h2&gt;

&lt;tr&gt;
&lt;td&gt;This issue has been resolved in an Appian hotfix/new Appian version. Please apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;h2&gt;&lt;span&gt;Symptoms&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Following an upgrade of Appian, select &lt;a href="https://docs.appian.com/suite/help/latest/Connected_System_Object.html"&gt;Connected System&lt;/a&gt; objects fail to load with the below error message:&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-13/pastedimage1575484631196v1.png" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;In the application server log, the below error message will be printed:&lt;/span&gt;&lt;/p&gt;
&lt;pre&gt;&lt;span&gt;YYYY-MM-DD HH:MM:SS [localhost-startStop-1] ERROR com.appiancorp.connectedsystems.http.migration.configobject.MigratePersistedConnectedSystems - Error persisting, migration will be skipped &lt;span class="code-keyword"&gt;for&lt;/span&gt; &lt;span class="code-keyword"&gt;this&lt;/span&gt; connected system: ... com.appiancorp.suiteapi.content.exceptions.InsufficientNameUniquenessException: Name is insufficiently unique&lt;/span&gt;&lt;/pre&gt;
&lt;h2&gt;&lt;span&gt;Cause&lt;/span&gt;&lt;/h2&gt;

&lt;li&gt;&lt;a href="https://docs.appian.com/suite/help/18.2/Hotfixes.html#hotfix-package-s"&gt;18.2 Hotfix Package S&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;If you require a hotfix for Appian 17.4 - 18.1, please open a support case with Appian Support.&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Action&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.&lt;/span&gt;&lt;/p&gt;
&lt;h2&gt;&lt;span&gt;Workaround&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span&gt;There are two workarounds that can resolve this issue:&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span&gt;1) Recreate Connected Systems&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Create a new Connected System object with the same credentials.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Update your integrations to use this new Connected System object.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Remove the old Connected System object you are replacing.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;&lt;span&gt;2) Resolve Naming Clash and Re-run EncryptionMigration&lt;/span&gt;&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Find the Application that has a matching name to a Connected Systems object. Enter the Application Context for that App (i.e. click on the application in /suite/design/)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;In the top right, click the gear and select &amp;quot;Application Properties.&amp;quot;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Rename the Application and click &amp;quot;Save Changes&amp;quot;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;h4&gt;Cloud&lt;/h4&gt;
&lt;p&gt;&lt;span&gt;Open a case with Appian Support and note to the case description that you are experiencing&amp;nbsp;behavior in line with this article. Ensure to confirm on the support case that you have performed the above steps for the second workaround option.&lt;/span&gt;&lt;/p&gt;
&lt;h4&gt;&lt;span&gt;On-Premise&lt;/span&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;Add the following line to&amp;nbsp;&lt;strong&gt;custom.properties&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;file in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code&gt;&lt;tt&gt;&amp;lt;APPIAN_HOME&amp;gt;/conf:&lt;/tt&gt;&lt;/code&gt;
&lt;div class="content-scrollable-wrapper"&gt;
&lt;pre class="code-java"&gt;conf.suite.RERUN_CS_ENCRYPTION_MIGRATION=&lt;span class="code-keyword"&gt;true&lt;/span&gt;&lt;/pre&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;Start the application server.&lt;/li&gt;
&lt;li&gt;Once the environment is accessible again, you can remove the added line from the &lt;strong&gt;custom.properties&lt;/strong&gt; file.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;&lt;span&gt;Affected Versions&lt;/span&gt;&lt;/h2&gt;
