If you are working in the PeopleSoft, we may have to face this kind of issue during migration
We all have something in mind that how to roll back the changes in PeopleSoft after doing migration.
Unfortunately, we don’t have that option. But we can take the backup from target instance before doing migration.
This would be the simple way
For our understanding let us consider HR_DEV (development instance) and HR_PROD (production instance).
Go to upgrade session the HR_DEV instance.
Step – 2
Uncheck all the upgrade Tick box.
Repeat it for all the definitions in the project and save the project
Step – 3
Go to Tools > copy Project> To Database
Now copy project to HR_PROD
Note: since we unticked the upgrade checkbox only definitions will be migrated .
Go the HR_PROD
File > open> project> project_name
Verfiy the definitions by comparing to HR_dev
Go to tools > copy Project > To file
Now you have successfully taken the backup of original codes. This may help you to roll back the changes. If there is any issue with migration.
