New user to the board, may end up being a new user to Nethserver as well. I've been running SME Server at home since before it was SME Server, and am looking into possibly migrating to another platform. My data, and particularly my emails, go back for at least 15 years, and I don't want to lose them.
I have a number of web apps running on my server (a couple of Joomla! instances, a Nextcloud server, a web page for my home weather station, etc.) that I'll want to migrate. I also have a number of contribs installed, but it looks like there are comparable modules available here, which should make that straightforward enough.
I'm sure I'll have questions, but I'll see what I can find in the docs/wiki/forum first.
