I just switched to a different instance that is more focused on my interests (Cyber-sec and IT).
The process of creating a new account was as easy as before, but there is not really a migration path like in Mastodon, so I ended up editing my Bio to link the new profile, and adding Old at the end of my Display name. I then had to manually suscribe to all of the communities I was following before by searching for them by !communityname@instance, that part was too manual, too slow and definitely needs streamlining.
Some of the communities I followed before had never been accessed from my new instance, so I'll have to wait a bit to start seeing posts and comments, but that was expected as I am beginning to understand how federation works.
My old comments and posts will not be migrated (there's currently no way to migrate them), but that's ok, I plan on leaving the old account up for about a month.
All in all, not a terrible process, but exporting/importing followed communities/followers/followed users would be a very welcome addition for users looking to migrate to a different instance.
