In Parallels RAS 19.3 the PowerShell module is named RASAdmin and it supports version 4.0 (latest), version 3.0 and version 2.0.
This version is the one loaded by default by the system or if the RequiredVersion is not specified when importing the module.
This version keeps backward compatibility with the older RASAdmin modules found in previous versions. It allows administrators to use existing scripts with minor modification. To make use of a previous version, one needs to specify the RequiredVersion (eg. 3.0) when importing the module:
Version 3.0 - Parallels RAS 19
Version 2.0 - Parallels RAS 18
