Powershell Module GUID

Question

Can anyone tell me what the recommended practice is for PowerShell Module GUID's. Initially a new Module gets labeled with a GUID. When I later come back to update/extend/change the module, I increment the ModuleVersion value, but should the GUID value also be changed?

The [`GUID` (Globally unique identifier)](https://nl.wikipedia.org/wiki/Globally_unique_identifier) should stay the same. If you e.g. upload your script to the [PowerShell Gallery](https://www.powershellgallery.com/), it identify it as the same script/module and append the new version to the Version History. — iRon, Aug 10 '18 at 11:26

The GUID identifies the module, not the version. Hence the GUID should not be changed.

The module Guid is defined in your module's psd1.

And you and get other module's Guid by runing (Get-Module -Name [moduleName]).Guid
