WARNING! WARNING! WARNING! Migration REQUIRES manual intervention! Almost all commands have different parameter signatures that often cannot be automatically converted. Or some commands are split into two commands. Or some commands offer only partial functionality afterwards. Use Read-AzScriptFile to get a list of all places where you need to adjust things. This command really is only there so you don't have to do the part we already can automate, but alone this will not be enough! .PARAMETER Path Path to the script-file(s) to convert. .PARAMETER Type What kind of module to migrate.

You can find the rules used in the module's data folder or on Github: https://github.com/FriedrichWeinmann/PSAzureMigrationAdvisor/tree/master/PSAzureMigrationAdvisor/data With this parameter, you can have the tool use instead your own transform/scanning ruleset.
