FEP-8b32 is designed to be compatible with existing implementations. The upgrade path for Mastodon may look like this:

1. Support multiple public keys per actor
2. Start publishing second Ed25519 key as described in FEP-521a
3. Start adding FEP-8b32 integrity proofs in addition to LD signatures (as specified in "Backward compatibility" section of FEP-8b32)
4. Stop adding LD signatures
