Hi Kathryn.
Yes, unfortunate news about home.social.
Here's a great write-up on how to transfer and what things you need to be careful about:

@Kathryn934 @admin Basically
* export your data (follows, lists, bookmarks, etc.; in addition export the complete archive, just in case)
* create new account on new server
* create alias on the new server that points to the old server
* go to old account and initiate the migration
