Need to migrate Goals, Goal Library, Complete Goal Plans and Completed Performance Documents from one instance to another. Both instances on 21A. I am aware of the objects that can be migrated. But looking for guidance, advise, watch-outs doing this exercise. Questions:

1) What data will not be migrated?

2) What setup steps need to be completed before migration?

3) Is there a specific sequence to perform the migration?

4) What are the known issues or restrictions with HDL for Goals and Performances

Thanks!
