How to convert from a GoDaddy Office 365 Email Essentials account to a full M365 Business Standard?

I am currently supporting a client who is using a GoDaddy Office 365 Email Essentials account, that they purchased along with their domain registration.

They now have need of the full suite of services offered with a Microsoft 365 Business Standard account.  However, it's my understanding that the GoDaddy tenants are a specialized product that isn't truly a native Microsoft 365 account.  Is this true?  If so what would the requirements be to migrate the user's account to a full Microsoft 365 Business Standard account?
