Retain important PeopleTools tables data during the Application upgrade.
We are in the middle of the PeopleTools and Application upgrade follow the path PeopleTools 8.51/HCM 9.1 to PeopleTools 8.55/HCM 9.2. After couple of MTPs, we have noticed that the during the Application Upgrade, the step of Exporting/Importing PeopleTools System Tables (mvprdexp.dms and mvprdimp.dms script), the PeopleTools tables of the target database has all the data getting replaced from the source database. Below are examples of the some of the PeopleTools tables which are getting overlaid with source database.

What is the best practice to preserve them. Our concern now is that we want to achieve recent Tools definition data for our next Go-Live, instead of a 10 months gap the time the source database was created after the initial pass. Thank you in advance for the response..
