@_astronoMay you can set up your account to kind of forward to the new one. This won't move your posts, but you can leave up this older account while mostly not worrying folks will follow you here.

Also I would download all your posts in an archive and maybe you can recreate a few threads over time... it'll be different, but they might feel relevant again!

Setting the redirect would be in https://mastodon.online/settings/migration
