Great plugin but false advertised since it doesn't support bungeecord! It can only be installed on spigot. Once the plugin can be installed to bungee I'll change to 5 stars!

Seems like a good resource, but you would have to add some kind of verification for accounts without the migration cape (accounts created after a specific date for example), can't join the server whilst they are migrated. Hypixel has their own website for this that uses the Microsoft API to verify the account.
