Obtaining Specific PowerCLI Versions from the PowerShell Gallery
We always recommend how everyone should be on the latest and greatest version of PowerCLI. However, we also recognize that isn't always possible. Whether it be for testing and validation, working around known issues, and so forth, there are reasons and needs to be able to obtain prior versions of PowerCLI from the PowerShell Gallery. The Save-PowerCLI function can streamline the download process of retrieving those specific versions of PowerCLI.
