Answer
In Latest versions(v2022+), we have a drop down available for selecting owner on terminate as user, manager, secondary manager etc.,. In this case, if we populate manager's manager value in secondary manager either With the help of preprocessor during import or by directly mapping user manager's manager to secondary manager during user import, then we can select 'Owner on terminate' as secondary manager. This would make the manager's manager as owner or terminate for the user.
However, in older version(5.5SP3.12 prior), we do not have option to select from the dropdown for Owner on terminate. In this case, we can build an analytics control to return manager's manager and directly update the owner terminate with manager's manager using CSV upload.
Once the owner on terminate is set, you can create the corresponding user update rules to transfer ownership of objects when the user is terminated.
