#fedihelp I'm attempting to migrate to New account: @robphippen

I have created an alias on my new account on mastodon.art to this account (@robphippen - see screenshot)

When I attempt to 'Migrate' from my settings on mastodon.world to [email protected] I get told that it is not an alias. (see other screenshot).

Am I doing something wrong, or do I need to ask help from the admins.
