Issue with custom text values in Classification Set migrations
I'm sharing in case you run across this issue or have a solution.
I've run across an issue with migrating classification rules containing custom text values. If the old rule contains a rule type of Regular Expression and a custom text value in the "To" field, the regex does not migrate.
I open the rule in the new Classification Sets interface, go to Rules, then click Migrate. The migration completes but the rule screen is blank with the message “Drag and drop a function to get started”. The original rules are missing. (There is no "try and migrate again" option.)
Ok. So, I needed to manually rebuild the rules. (If there had been a lot of rules, that would have been a burden.) I rebuilt the rule, saved the rule, and activated it. Some days later, I checked the report and the report did not show the expected custom value but showed "Unknown" instead. After a week, it still showed "Unknown".
I then changed the new rule to use $1 instead of the custom value. I checked the report and that worked. I then changed the rule back to using a custom value, and the rule stopped working, showing “Unknown”.
This happened with every classification I tried that had a custom value set in the rule (4 separate classifications). I have submitted a ticket to Adobe.
I tried creating a brand-new rule in Classification Sets that used some custom text. That worked.
