We have six Plesk servers in our Expand hierachy: 2 x Plesk Linux Servers 2 x Plesk Windows Servers 1 x Central Mail Server 1 x Central DNS Server We have to restore 1 x Plesk Linux server. We did a clean installation of Plesk and then restored the backup file. Now we have numerous major problems. 1. The first and biggest problem is some domains (with their mailboxes!) are just dissappearing off the Central Mail server. We have lost numerous mail accounts and domains and we are still loosing some more. It seems Plesk Expand is trying to sync and in the process deleting old clients and mailboxes off the Central Mail server. 2. Some clients had updated their DNS in the Expand hierarchy. Now these clients domain DNS records are pointing back to the old server, the updated records are gone. We cannot determine how wide this problem is but we are having multiple calls about it. 3. Expand client relations with Plesk client relations on the restored server is missing. There are over 300 clients to assign and we cannot do this by hand. We need an automated way to do it. We need some serious help and we are always logging a paid for ticket about this. Please if anyone has advice give it now.
