We are running a flow application on an obsolete Ubuntu 12 server. We want to move this application to a Ubuntu 14 server which is in an extended security update program. We want to retire the Ubuntu 12 server.
I am a newbie on this matter. I noticed there is a manual for setting up Flow on Ubuntu but we’re also running Plesk on the Ubuntu 14 server with a large number of small websites. Setting up Flow should not interrupt the other websites.
How should I proceed?
