EDITED: Forget the posts question.
I know I'm opening myself up for an onslaught of responses I won't understand, irrelevant replies, and redundant replies, but I'm asking anyway:
I'm considering switching from Mastodon . social to mstdn . social. Stux is awesome, I need to break from zillions of bots as best I can.
I've never tried to transfer before. I have a good guide, but in real life, do followers get moved reliably?
Tips?
*Bracing for replies*
Posts don't transfer over, but as long as you leave the old account in existence the old posts will also stay in existence, and will redirect people to your new account.
I moved over 200k followers on FediTips and it went okay. If followers get "stuck" you can do another transfer after 30 days, and it usually brings the remaining ones over that are working.
(Some of them stayed "stuck" after several repeated attempts so I did a deep dive on the causes, they were all on broken servers, so they were never actually following me.)
@FediThing I don't care about most followers, but since I have so many, I can't weed them out so... Thank you!
It did take me about two or three passes to get all the genuine followers over to the new account. It was something like 75% in first transfer, 20% in second attempt, a few percent in third pass and the rest were broken anyway.
The reason there's the 30 day mandatory gap between follower transfer attempts is because it can take days or weeks for some followers' servers to acknowledge the transfer, depending on how busy they are. (So, don't panic if it doesn't all work straight away, it takes time for some of the transfers to happen. 
)
@FediThing Oh good, thanks. I really don't care THAT much. People will find me.
But lists? My Mastodon deck interface is all about lists/columns. I lose those?
Moving lets you keep your followers, follows, bookmarks, lists, mutes, block and domain blocks. You can transfer them all.
@FediThing Oh good!!!
