We are considering a new faster server to replace both Plesk5 and Plesk6 systems (to a single machine).
This will run the newer versions of Plesk that allow more PHP configuration options, but that also means they run PHP 5.3 at minimum.
The new server has been brought online. Over the next few days we will start the migration process.
The new server has plenty of RAM and disk space to cover consolidation of the two older servers.
The new hostname is "east.lvcs.net".
This forum is now operating on the new server.
