@HeatherMJ @DoubleTreble go looking for @FediTips 's very helpful guide, and do the steps in the right order.

In particular, this: https://fedi.tips/transferring-your-mastodon-account-to-another-server/ .

There are lots of other tips here: https://fedi.tips

@FediTips just moved from there to another server, following your instructions (which I found very clear and easy to follow).
