we have Presentation Server on production and test environtment, both with typical version 4.5 and currently connecting to the same license server (version 4.5). we are trying to migrate to a new license server (v11.5), and shutdown the old license server if everything works ok after migration.
so we installed the license server on a new machine, return and download the license on myctrix.com, and upload the new license (with correct new hostname, with matching case) to the new machine. we then tested by pointing one of the servers from test farm to this new license server, but it didn't work. when logging in from client, we keep getting error:
"Citrix Presentation Server license acquisition error (500): Unable to acquire a license from (server name) server. Please contact your system administrator or open Event Viewer for more details."
