A site collection can not be upgraded.
Upgrade-SPSite -identity <site collection url> -VersionUpgrade -Unthrottled
When I performed the command above, the exception below was thrown.
Upgrade-SPSite : SPSiteHealthChecker: Microsoft.SharePoint.SPException exception thrown in SPSiteHealthChecker.Test(): Der Vorgang kann nicht erfolgreich beendet werden.

Site collection health check is also broken.
Any help and explaination would be appreciated!
