 I have updated a CDT and table by adding a new column and deployed those changes to PROD.

&lt;p&gt;First we cant have the updated CDT in the old instances&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;You can try this&amp;nbsp;&lt;/p&gt;
&lt;p&gt;As you said you have backfill data for the&amp;nbsp; instances&amp;nbsp;&lt;/p&gt;
&lt;p&gt;So for each instance&lt;/p&gt;
&lt;p&gt;1.you can create a process variable&amp;nbsp;of type&amp;nbsp;newly created cdt&amp;nbsp;&lt;/p&gt;
&lt;p&gt;2. Before writing to data store call a script task set the other details from the old CDT process variable&amp;nbsp; to the new cdt process variable along with new value in the new column&lt;/p&gt;
&lt;p&gt;3. update the write to datastore with new process variable and save the edit&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Note: This solution is just to fix the instance to save appropriate data . if the data is to be&amp;nbsp;forwarded in the parents process or another actions needed&amp;nbsp;&amp;nbsp;than another fix needs to planned.&amp;nbsp;&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
