In case it is necessary to move a master role to another server and then make its old master Parallels Infrastructure Manager (PIM) a slave on the new master PIM node, please use the following procedure (it is applicable to both the Linux and Windows platforms):

1. Make a backup of the PIM infrastructure as described here.

2. Check all available nodes in the old master PIM node:
[root@oldmaster ~]# vzagroup list
oldmaster.hostname online master
slave.hostname online slave
newmaster.hostname online slave
Operation 'list' completed successfully

3. On the master node, destroy the group by removing all of the slaves:
[root@oldmaster ~]# vzagroup removeSlave slave.hostname
[root@oldmaster ~]# vzagroup removeSlave newmaster.hostname

4. On the slave node (which should be the new master node), create a new group by adding the slaves (vzagroup will ask you for credentials):
[root@newmaster ~]# vzagroup addSlave oldmaster.hostname
[root@newmaster ~]# vzagroup addSlave slave.hostname

Please also see this related article about PIM clustering.
