The following system configuration will be migrated from < current > to < next >.
Therefore, we need to clarify how to migrate Pega-specific data (Rules, cases, etc.).
Please tell me how to migrate each type of Pega-specific data.
Currently, I think we have to be aware of two things: rules and cases.

Also, please let us know if there are any precautions to be taken when upgrading PostgreSQL and Pega Platform at the same time.
