Trying to restore a case from backup fails with error:
(0x80004005): 23505: duplicate key value violates unique constraint "pk_fac_objectviewed"
During the restore process, you must map users 1:1.
You'll need to pick a unique user in the current database to map the users within the case back up to.
You cannot map multiple users to a single user in the current database or it will fail with this error.
Unable to map several users to a single user. This had been allowed in previous versions, but had negative consequences, so we changed the requirement.
