How do I upgrade my existing Silverstack license?

If you decide that you would like to upgrade your Silverstack yearly subscription to a Silverstack XT yearly subscription, please contact us at

Upgrading to Silverstack XT is a process done manually by us via a prorated refund where you will receive a refund for the time not using Silverstack in the current period and billed accordingly for the rest of time using Silverstack XT.

You can upgrade to Silverstack Lab via the automatic upgrade form.
