Can I Move My Mastodon Username to Another Server?
One of the most common anxieties for users selecting a Mastodon server with a Mastodon username search is the fear of committing to the wrong instance. What if the server goes offline? What if the admin changes the rules or closes registration? What if you later want to move to a more relevant community?
The good news: Mastodon has a built-in account migration system specifically designed to address this. Your choice of instance is not as permanent as it might seem.
How Mastodon Account Migration Works
Mastodon's migration feature allows you to move your account identity from one server to another in a way that preserves your most valuable asset: your followers.
The process involves four steps:
Step 1 — Create your new account: Register on your destination instance with your desired username. Your old and new accounts will exist simultaneously during the transition.
Step 2 — Set an account alias: In your new account's settings, link back to your old account by setting it as an "alias." This creates a cryptographic verification that the two accounts belong to the same person.
Step 3 — Initiate migration from the old account: In your old account's settings, go to "Account" → "Move to a different account" and enter your new account address. Confirm the migration.
Step 4 — The redirect activates: Your old account is converted to a "tombstone" — a locked, read-only profile that displays a banner reading "This user moved to @username@newserver.com" with a button for visitors to follow the new account. All your existing followers are automatically redirected to your new account without any action required from them.
What the Migration Transfers and What It Does Not
What moves with you:
- All of your followers (automatically, without them needing to re-follow)
- Your following list (the accounts you follow)
- Mutes and blocks
- Your bookmarks
What stays behind:
- Your posts (toots) — these remain on the old server and are visible there as long as the server stays online, but they do not appear on your new profile
- Your likes/favorites
- Your media uploads
This means migration is best understood as a follower transfer with a clean start on content. Many creators use this intentionally — migrating to a self-hosted instance after building an audience on a public server, starting fresh with new content on the new home while all their followers follow along automatically.
Why This Changes the Strategic Calculation (Growth Insight)
The ability to migrate followers without losing them is a capability that does not exist on any major centralized social media platform. On Instagram, Twitter, or YouTube, your audience is bound to the platform's database — you cannot export your followers and rebuild on a new account or platform.
Mastodon's migration system enables a growth strategy that is unique to the Fediverse: build on the flagship instance first, migrate to your own infrastructure later.
The practical playbook for brands and creators is:
- Start on
mastodon.social— maximum discoverability, no setup cost, easy onboarding - Grow your follower base through quality content
- When the time is right, deploy your own Mastodon instance (
social.yourbrand.com) - Migrate — your entire follower base transfers automatically
- You now have a brand-owned, self-hosted presence with full namespace control and an established audience
This pattern is impossible on any other major platform.
Frequently Asked Questions (FAQ)
Can I keep my exact username when I migrate?
You can keep the first half — the local username (e.g., john) — provided that name is not already registered on your destination server. The second half (the instance domain) will always change to reflect your new server. If the specific username you want is already taken on the destination instance, you will need to choose a variation or select a different server.
What happens to my old posts after migration? Your old posts remain on the old server, visible to anyone who visits the tombstone profile. They do not transfer to your new account. Your new profile starts with an empty post history. This is a known limitation of the current ActivityPub migration specification and a common point of discussion in Mastodon's development roadmap.
Can I migrate back to the original server after moving? Yes, technically — the migration process can be run in reverse, provided your old account's tombstone is still accessible and the server is still online. However, a "return migration" still does not recover your old posts, and the process requires the same setup steps as the initial migration.
What exactly is a "tombstone" account? A tombstone is the locked state of a migrated-away Mastodon account. It cannot post, follow, or interact. It displays a profile banner pointing to the new account, and it continues to serve as a redirect for anyone who tries to visit the old profile URL. It remains visible as long as the original server remains operational.
Lock in your preferred username now, build your audience, and migrate to your own infrastructure when you're ready.
