@aggrobadger so you can just make an account on the new instance, like you can just do that.
And then on your old one, under preferences I think it is, there's an option to make that old account redirect people to your new one.
@aggrobadger there's a tool for finding instances that'll work for you here https://instances.social/
a lot of the larger and furrier ones are also in https://awoo.space/about/more#whitelist
which is a little easier to look through.
