This article aims to describe how to overwrite/restore account backups without restoring the email data.
Utilize the "restorepkg" script to restore the account backup. The "restorepkg" script has the ability to disable individual modules involved in the restore. The common options needed for this procedure are Mail and skipaccount. Both options will need to be disabled to accomplish the task.
The below documentation URL contains more details on the different operations that could be performed during the restoration.
For example, the below command will restore the account while skipping the mail.
/scripts/restorepkg --skipaccount --disable=Mail cpmove-account.tar.gz
