How to perform major Plesk upgrade in the Multiserver environment?
The proper way to perform major Plesk update is the following one:
- Set a service node to the Maintenance mode
- Perform upgrade to the next Plesk release on the service node first
- Perform upgrade to the next Plesk release on the management node.
Warning: If the management node is upgraded first, the service nodes will be marked as Unsupported and became unavailable to manage.
