• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Debian 6 (Squeeze) stable

Is there any good and up-to-date migration doc ? what are steps in migrating from Debian 5 ( 10.1) to Debian 6 ( 10.2)
any important software upgrade is generally documented ( RELEASE UPGRADE DOC)
1 - backup Plesk 10.1 data=> what do we need to back up ? ( doc ? )
2 - update Debian 5=> 6 , cool well documented ... it's an update so what will happen to Plesk files ?
3 - install Plesk 10.2 (final)
4 - restore Plesk data into Plesk 10.2 ( doc ? )
 
JessicaS., I guess you must be on quite old OS if newer version of Plesk doesn't support it - normally we EOL OS only after it is EOLed by its vendor.

As Plesk 10.2 supports Debian 5 as well, it is quite okay to upgrade to 10.2 and keep the same OS. If the current OS is obsoleted, the best way is to install a new box - with new OS and new Plesk and then perform migration there. The migration process is well documented here. The upcoming Plesk 10.3 (early preview available) includes migration of server-wide settings in addition to content (domains, mailboxes, etc) which makes migration easier.
