Ability to migrate accounts from one plesk node to another
It would save huge amounts of time if the admin using the customers plesk account credentials was able to migrate the whole account from the previous hoster without needing to have root access to the server like you can do in cpanel. In order to migrate plesk customers from other companies you need to do it manually !
often times a reseller or server owner will not relinquish root-level credentials for movement of a single site to a new destination. a tenant would have only their plesk subscription login details. PMM should include functionality to connect using these credentials, start a backup, possibly with a remote destination (the target server), and then restore that data when the backup is done.
its very critical in plesk but in whm cpanel superb within 10mins
