&lt;h2&gt;Symptoms&lt;/h2&gt;
&lt;p&gt;The following error is observed in the application server log after an upgrade or migration:&lt;/p&gt;
&lt;pre&gt;FATAL com.appiancorp.common.web.StartupHaltingServletContextListener - Halting JVM startup: Administration console migration failed.
com.appiancorp.suiteapi.common.exceptions.AppianException: Administration console migration failed. (APNX-1-4282-000)&lt;/pre&gt;
&lt;h2&gt;Cause&lt;/h2&gt;
&lt;p&gt;The migration of the primary database cannot&amp;nbsp;be completed for one of the following reasons:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The migration has already occurred and is attempting to complete for a second time.&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;The database software/version cannot support the schema. If this is the case, it is likely that the environment is using a database that is not specified in the Appian&lt;a href="https://docs.appian.com/suite/help/latest/System_Requirements.html#databases" target="_blank"&gt; System Requirements&lt;/a&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;In order to determine the exact cause of the issue,&amp;nbsp;the following information&amp;nbsp;is necessary:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The exact version and hotfix the&amp;nbsp;environment is being upgraded&amp;nbsp;to and from.&lt;/li&gt;
&lt;li&gt;The detailed steps followed to&amp;nbsp;complete the upgrade/migration.&lt;/li&gt;
&lt;li&gt;A SQL dump of the primary database.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Action&lt;/h2&gt;
&lt;ol&gt;
&lt;li&gt;Gather&amp;nbsp;the above information.&lt;/li&gt;
&lt;li&gt;E&lt;span style="color:#000000;"&gt;xamine the SQL dump of the primary database.&amp;nbsp;&lt;strong&gt;Note:&lt;/strong&gt; As this will likely contain PII, do not upload it to&amp;nbsp;any existing support case. If Appian Support is required to analyze the the SQL dump, it&amp;nbsp;must be examined via WebEx.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;If it is determined that the database cannot support the schema, ensure that the environment is using a database that is specified in the Appian &lt;a href="https://docs.appian.com/suite/help/latest/System_Requirements.html#databases" target="_blank"&gt;System Requirements&lt;/a&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;If it i&lt;span style="color:#000000;"&gt;s determined that the migration has previously been performed (e.g. the data that failed to migrate already exists in the database), revert the primary database/environment to a backup taken before the upgrade/migration. Perform the upgrade/migration again and ensure that the data migration is only performed one time.&lt;/span&gt;&lt;/span&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span style="color:#000000;"&gt;&lt;span style="font-weight:400;"&gt;&lt;span style="font-weight:400;"&gt;&lt;strong&gt;Additional Context:&lt;/strong&gt; A SQL dump will contain the SQL statements that should be run in an empty database to regenerate all of the data/tables that existed in the database at the time of the dump. Since the above error &lt;/span&gt;&lt;/span&gt;&amp;quot;&lt;span style="font-weight:400;"&gt;&lt;span style="font-weight:400;"&gt;&lt;code&gt;Administration console migration failed.&lt;/code&gt;&lt;/span&gt;&lt;/span&gt;&amp;quot; suggests that the migration failed, it would be unexpected to see the SQL statements to update the tables the way a migration would. If the SQL dump does contain these SQL statements, it is likely that the&amp;nbsp;&lt;span style="font-weight:400;"&gt;migration has previously been performed.&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;/li&gt;

&lt;h2&gt;Symptoms&lt;/h2&gt;
&lt;p&gt;The following error is observed in the application server log after an upgrade or migration:&lt;/p&gt;
&lt;pre&gt;FATAL com.appiancorp.common.web.StartupHaltingServletContextListener - Halting JVM startup: Administration console migration failed.
com.appiancorp.suiteapi.common.exceptions.AppianException: Administration console migration failed. (APNX-1-4282-000)&lt;/pre&gt;
&lt;h2&gt;Cause&lt;/h2&gt;
&lt;p&gt;The migration of the primary database cannot&amp;nbsp;be completed for one of the following reasons:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The migration has already occurred and is attempting to complete for a second time.&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;The database software/version cannot support the schema. If this is the case, it is likely that the environment is using a database that is not specified in the Appian&lt;a href="https://docs.appian.com/suite/help/latest/System_Requirements.html#databases" target="_blank"&gt; System Requirements&lt;/a&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;In order to determine the exact cause of the issue,&amp;nbsp;the following information&amp;nbsp;is necessary:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The exact version and hotfix the&amp;nbsp;environment is being upgraded&amp;nbsp;to and from.&lt;/li&gt;
&lt;li&gt;The detailed steps followed to&amp;nbsp;complete the upgrade/migration.&lt;/li&gt;
&lt;li&gt;A&amp;nbsp;SQL dump of the primary database.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Action&lt;/h2&gt;
&lt;ol&gt;
&lt;li&gt;Gather&amp;nbsp;the above information.&lt;/li&gt;
&lt;li&gt;Examine the SQL dump of the primary database.&amp;nbsp;&lt;strong&gt;Note:&amp;nbsp;&lt;/strong&gt;as this will likely contain PII, it may be necessary to examine the contents with the customer via WebEx.&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;If it is determined that the database cannot support the schema, ensure that the environment is using a database that is specified in the Appian &lt;a href="https://docs.appian.com/suite/help/latest/System_Requirements.html#databases" target="_blank"&gt;System Requirements&lt;/a&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-weight:400;"&gt;If it is determined that the migration has previously been performed (e.g. the data that failed to migrate already exists in the database), revert the primary database/environment to a backup taken before the upgrade/migration. Perform the upgrade/migration again and ensure that the data migration is only performed one time.&lt;/span&gt;&lt;/li&gt;
