Citrix Virtual Apps and Desktops SDK

Get-AppLibInstalledDBVersion

Gets a list of all available database schema versions for the AppLibrary Service.

Syntax

Get-AppLibInstalledDBVersion
   [-Upgrade]
   [-Downgrade]
   [<CitrixCommonParameters>]
   [<CommonParameters>]
<!--NeedCopy-->

Description

Gets the current version number of the Citrix AppLibrary 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-AppLibDBVersionChangeScript 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.
