ADFS upgrade database to v4 overwrite configuration

Hello,

I am attempting an upgrade of the ADFS database, after replacing the servers with new Windows 2016 servers.
I have used the script to create the database (new database), as the account I am using does not have permission to create databases (trying to replicate what is in production).
When running the Invoke-AdfsFarmBehaviorLevelRaise I get the following error.
Invoke-AdfsFarmBehaviorLevelRaise : An AD FS configuration database with the same name already exists; specify that the existing database is to be
overwritten.
I can see nothing in the powershell command 'invoke-xxx' to force an overwrite of the database.
I read that you can specify -OverwriteConfiguration, but this just gives me an error this command doesnt exist.

Any help would be appreciated.

Thanks
Matt
