# Get-HypInstalledDBVersion

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

Syntax

Get-HypInstalledDBVersion [-Upgrade] [-Downgrade] [-AdminAddress <String>] [<CommonParameters>]

Detailed Description

Gets the current version number of the Citrix Host 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-HypDBVersionChangeScript 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.

Downgrade Specifies that only schema versions to which the current database version can be reverted should be returned. false false
AdminAddress Specifies the address of a XenDesktop controller the PowerShell snap-in will connect to. You can provide this as a host name or an IP address. false false Localhost. Once a value is provided by any cmdlet, this value becomes the default.
