Syntax

Get-VusInstalledDBVersion
   [-Upgrade]
   [-Downgrade]
   [-SkipCertificateValidation]
   [<CitrixCommonParameters>]
   [<CommonParameters>]

Description

Gets the current version number of the Citrix VdaUpdateService Service database schema when called with no parameters.
When called with the -Upgrade parameter, gets the service schema version numbers to which an upgrade could be performed.
When called with the -Downgrade parameter, gets the service schema version numbers to which a downgrade could be performed.
The SQL scripts to perform schema upgrades and downgrades can be obtained using the Get-VusDBVersionChangeScript cmdlet. Citrix recommends that where possible service schema upgrades are performed using Studio rather than manually via the SDK.
Only one of the -Upgrade or -Downgrade parameters may be supplied at once.
