We once did something like that.

Basically it did something like that:
- Process is kicked off per user by some trigger
- Block all new jobs of the given user
- Wait until all currently running jobs have finished
- Disable the user in the LDAP and wipe the sssd cache for the user.
- Kill all their processes on the login nodes
- Move the data
- Re-enable the user in the LDAP
- Remove any blocks/limits of the user to start new job
- Mail the user that he/she can continue working again.

The whole process went pretty smooth.
