KB #5474 - How do I migrate all Plesk accounts from one Plesk node registered in PBAS system to another one?

CAUSE

Sometimes it is required to replace hardware or upgrade/change OS distribution of Plesk server.

upgrade PBAS system to the latest version
create new Plesk Container/server on new hardware node with new IP-addresses assigned
register the Container/server in PBAS system as a new Plesk node
migrate Plesk accounts one by one from source server to destination one using the following steps:
- migrate single Plesk client account from old Plesk node to the new one using Plesk migration manager interface
- resolve conflict for migrated Plesk client/domain in PBAS system on Top > Migration Director > Conflicts Resolver > Plesk Clients/Domains screen selecting the Plesk client/domain from destination server, clicking on Resolve link and selecting assign to existing subscription option (there will be only one existing Plesk client/domain subscription available)
- as soon as migrated Plesk client is working properly on destination server - delete the client on source server
- repeat the procedure above for every Plesk client on source server
as soon as all Plesk clients migrated from source server it should be possible to delete corresponding Plesk node from PBAS interface.
(optional) remap IP-addresses on the new Plesk node to have the same IPs as source node.
