- Plesk 11.x for Linux
Upgrade failed from 10.3.x to 11.5.30
Domains are not loading and they are not displaying in the Panel.
Direct upgrade from 10.3.x to 11.5 is not possible. There two ways to work around this:
Upgrade you Plesk 10.3.x installation to 10.4.4 then upgrade to 11.5.3.
Transfer the domains from your 10.3.x installation to Plesk Panel 11.5.30
Direct upgrade from 10.3.x to 11.x is not supported:
