For anybody interested in migrating to a new server, I followed this guide: https://fedi.tips/transferring-your-mastodon-account-to-another-server/ The process itself was much easier and quicker than expected, most of the work was everything else surrounding it (ie locating a new instance, redesigning my profile, updating my Mastodon links elsewhere). It's not quite as daunting as it seems, I wish I would've done this ages ago!
