The biggest thing missing from Mastodon remains the ability to *actually* migrate an account between servers.

The follower-migrate feature is not enough. I need to be able to migrate an entire account, including posts. And I should be able to do it without the former server cooperating (because of course servers can go down). I should be able to get some sort of cryptographic cert I can send to a new server with my posts and they'll be like "oh yeah, this is real, migrating u now".

@mcc Migrating posts without cooperation of the orginal instance would require an archive of whatever you want to keep somewhere else - including whatever non-public stuff you want to keep. Not impossible, but tricky for people with sensitive stuff in their archive.
@rst There's already a feature for people to download their own post history isn't there
@mcc There is - and it'll do the job if the user still has access to the former server. But "without cooperation of the former server" seemed meant to cover cases where they don't (perhaps because it just blew up). That could be mostly handled by the user regularly saving archival copies, but that requires planning ahead, and having a secure place to store the archive. Some people won't.
@rst at least give us the option to plan ahead
