Class xxx-Work <-- Is Classgroup, mapped to Table T1

Class xxx-Work-AA <-- belongs to above Classgroup

Class xxx-Work-BB <-- belongs to above Classgroup

Current we have an application in production with hundreds of in-flight cases mapping to each of the classes above Work-AA and Work-BB. The management want to decouple the 2 case types AA and BB, since they belong to different stakeholders now (there are some project history, but what's done is done).

In order to decouple the case tables at DB level:

1) I've asked the DBA to create new table T2 based on same definition as T1 above.

2) Updated class Work-BB to "is a classgroup", and created class group rule for Work-BB

3) Created DB-Admin-Table instance to map Work-BB class to new table T2

What I did above worked well for newly created cases. But I'm running into issue for in-flight cases. It seems there is a mismatch between

Assignment pxRefObjectKey and Case pzInsKey. I anticipated this of couse, so I also asked the DBA to update the following fields to make sure they reflect xxx-Work-BB (new table) instead of xxx-Work (old table).

Case Table T1:

pzInkKey

assign_worklist:

pzInsKey, pxInsName, pxRefObjectKey

But after the DBA run the query I don't see the new values reflected in the assign_worklist table when I view the instance from Pega. I don't know why this is.

Also, what do you think of my approach?
