Upgrading PSU ZIP IIS Installation

I was looking to update to the latest version but I couldn’t find any info on how to do this with the ZIP download. I backed up the appsettings.json and web.config file. Is there anything else I’m missing? A dashboard loaded but got the following error when it loaded. We do have some secret variables saved using the BuiltInLocalVault:

Errors occurred while loading the format data file: …\PowerShellUniversal\Microsoft.PowerShell.SecretManagement\0.2.1\Microsoft.PowerShell.SecretManagement.format.ps1xml, , …\PowerShellUniversal\Microsoft.PowerShell.SecretManagement\0.2.1\Microsoft.PowerShell.SecretManagement.format.ps1xml: The file was skipped because of the following validation exception: AuthorizationManager check failed…

Is there something else I need to do since we’re storing secrets in the BuiltInVault?

Product: PowerShell Universal
Version: 1.5.8
