Upgrade by transfer
- Upgrade by transfer is the process of switching to the latest Plesk version by moving all hosting data and settings from the current Plesk server to a server with the latest version of Plesk installed. This strategy is preferred when upgrading servers with an OS that either falls under the end-of-life policy or is approaching the support termination date. Upgrade by transfer also allows to minimize downtime of services on the production server, as websites stay online while the transfer is in progress.
The following guide helps to perform an in-place upgrade of Plesk. If upgrade by transfer is a preferred method for you, please check our migration and transfer best practices guides:
Dist-upgrade for Linux
WARNING: Dist-upgrade is supported only on Plesk 12.5 and using the following scenarios:
Debian 6 to Debian 7
Debian 7 to Debian 8
Ubuntu 12.04 to Ubuntu 14.04
If Plesk is running on a Linux distribution that is not Debian 6 or 7, or Ubuntu 12.04, do not attempt to upgrade the operating system. Such upgrade paths are not supported by Plesk, and attempting to upgrade will damage your Plesk installation. Also, dist-upgrade on systems with older Plesk versions will damage Plesk installation.
