[Feature]: Easy Account Migration Wizard/Flow #1062
Description
Description
I'd like to have an app-blessed method by which I can migrate between two accounts I have, in a way that isn't confusing, doesn't require extra documentation or guidance outside of the app, and doesn't require me to go to the web pages of both accounts.
Suggested Solution
Have a setup wizard (like a full-screen popup setup thingie) with which you select a (logged in) account to migrate from, and a (logged in) account to migrate to, get a screen where you select if you want to import/merge your follows, blocks, filters, mutes, etc. (maybe allow the user to select exactly which things to import), and then a disclaimer screen that posts are not migrated, and then a final button to confirm migration.
This will, in the background, do the imports requested, set the alias on the new account, and do the migration on the old account.
Alternatives
Keep the current system as-is, leaving the migration to be web-based, requiring the user to put in the alias on the new account, and push the button manually on the old account, and still manually download mutes/blocks/filters/etc. and import them manually as well.
Additional Context
This will provide a "blessed" method by which users can easily migrate; a user might never (want to) touch the web interface, and only interface with mastodon through their app. As such, migration should also be easily possible through the app, with a flow by which they can migrate everything as they want, without needing to do the dance manually.
