I was wondering what this was about. I hadn't checked out this profile in a while. Updating a server was the thing that looked daunting to me when I considered hosting my own instance. If you blow my account away, it's fine. I'll probably just recreate some other time since I haven't used this much. Hard to get any of my friends/family to leave Facebook.
There's a feature to pack your data, migrate into another server, and send out forwarding addresses to all your people. In the Fediverse, you really only need one account, unless the locals on a server have some special concentration of topics you care about being involved in.
Mostly I'm newly divorced, moving, and overloaded with things to do in life. I'm just dropping down to one server from two in the Fediverse.
I did make some how-tos for going from 0-knowledge and small amounts of money to running your own server... http://ubuntu.wnymathguy.com/ will forward you to a Google Sites page set where I keep my notes on how to do it. I haven't edited in a while, so some of the notes show my struggles in the past.
