 I have changed the data type for some columns in a nested CDT ( from text to CLOB), therefore the CDT version has changed for both nested and main CDTs. 
 How would this affect the processes which were started before the change and have the old</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Change nested CDT version</title><link>https://community.appian.com/thread/50277?ContentTypeID=1</link><pubDate>Tue, 21 Nov 2017 10:19:59 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:ec5096e1-7cbe-4bda-ab76-9da764f6372f</guid><dc:creator>oanas</dc:creator><description>Hello &lt;a href="/members/puspendup403"&gt;Puspendu Pal&lt;/a&gt; ,&lt;br /&gt;
Thank you for your answer. I have only changed the data type from text to Clob.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Change nested CDT version</title><link>https://community.appian.com/thread/50250?ContentTypeID=1</link><pubDate>Mon, 20 Nov 2017 12:55:32 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:caeb4053-bbae-4fa0-8ce2-86120df9b1c0</guid><dc:creator>Puspendu Pal</dc:creator><description>Hello,&lt;br /&gt;
&lt;br /&gt;
There are chances the process instance may break( even if not passed by reference), depending on &lt;br /&gt;
1) The kind of changes done to the CDT &lt;br /&gt;
2) The kind of operation  done on the CDT in the long running process instance.&lt;br /&gt;
&lt;br /&gt;
Example, -  If you remove an column or change the data type of a column from text to integer  and  in the process instance you are trying to access that  removed column, then  there would be a failure.&lt;br /&gt;
&lt;br /&gt;
But in your case, since CLOB can accept Text data, I think you should be good.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Change nested CDT version</title><link>https://community.appian.com/thread/50230?ContentTypeID=1</link><pubDate>Sat, 18 Nov 2017 12:45:44 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:a7db0b52-49bd-4a02-ba2c-7de42cfc6169</guid><dc:creator>Jamal Case</dc:creator><description>You should be good if you updated the CDT using impact analysis one you made that change.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Change nested CDT version</title><link>https://community.appian.com/thread/50072?ContentTypeID=1</link><pubDate>Tue, 14 Nov 2017 13:50:47 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:f5170abd-6a22-4f45-8c1f-afcf5621ccfc</guid><dc:creator>oanas</dc:creator><description>&lt;p&gt;Hello,&lt;br /&gt; &lt;br /&gt; The CDT is not passed as reference in any of the Subprocesses...it is only given as input/output variable.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Change nested CDT version</title><link>https://community.appian.com/thread/50070?ContentTypeID=1</link><pubDate>Tue, 14 Nov 2017 13:35:12 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:a603fdc1-1fb0-417a-9e88-b2531001bcdc</guid><dc:creator>Vinay Kumar Rai</dc:creator><description>Hi,&lt;br /&gt;
did you pass the CDT variable by reference?, if yes then the Process should break, Appian strongly recommend not to pass the CDT as reference&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
