Mass IP addresses change in Plesk Control Panel

Solution: Using the special utility reconfigurator.pl in Plesk

If doesn’t exists - template will be created, otherwise it will be used to map IP addresses.

There is the special utility reconfigurator.pl in Plesk that allows you to change IPs in Plesk base and reconfigure domain settings with new IPs.

This utility is available in the /usr/local/psa/bin directory.

The new IP addresses must NOT exist in Server > IP Addresses list in Plesk control panel before replacement, they may be added on system level only. If IP addresses do not exist in the system, the utility will add new IPs to the system as well.

Setup Primary and Secondary (Slave) DNS server in Plesk.

Setup should allow zone transfer for the secondary DNS server in Plesk.
To allow it, secondary DNS server’s IP should be listed in NS records for all zones on Plesk server or it should be added to Access Control List (ACL).

ACL is be managed on the Server->DNS Settings->Common ACL page in Plesk CP.

In case if you wish to use non Plesk server as slave DNS, all DNS zones have to be created on the secondary DNS server in /etc/named.conf (this file location may be differ depending on OS) with ’slave’ type, for example:

Restart named after that. Now slave DNS server will get zones information from Plesk (master DNS server).

Repair and rebuild all mail configuration in plesk.

This can be done with Plesk mchk utility:

Example:

Also check for the options

mchk [OPTION]

–without-spam - restore all settings except for SpamAssassin configuration
–with-spam - restore all settings
–spam-only - restore only SpamAssassin settings

This utility rebuilds in line with Plesk database Qmail control files in the /var/qmail/control, /var/qmail/users directories and mail users’ settings. Also, it sets proper ownership/permissions for all mailboxes (/var/qmail/mailnames/*).
