Hi, I am migrating from an old server running ISPConfig Version: 3.1.15p2 on Debian Stretch. To a new server running ISPConfig Version: 3.2.5 on Ubuntu 20.04. My personal experience on Debian Stretch was fine but Debian lacked the repository for many components to be upgraded. This is why I chose to migrate to Ubuntu 20.04 as Ubuntu tends to be more up to date. The old server will be reinstalled and I will attempt to configure it as a back-up web server. That being said, I have already installed ISPConfig on the new server. And have purchase the migration tool. But before going ahead and start migrating everything, I wanted to ask for some tips. Firstly here is what I have to migrate : 55 Mailboxes 1 Catchall 15 Mail Forwards 13 Websites 7 SQL Databases 7 Databases Users 7 FTP Users ~900GB on /var I am looking for some tips to plan a procedure with minimal down time. I of course already looked up https://www.howtoforge.com/tutorial...-confixx-plesk-to-ispconfig-31-single-server/ which provides a detail explanation on how to migrate from 1 server to another. But it lacks in details about availability of both servers.
