hi i already have a running VSZ which had X sn on it. I added temporary AP lic bcos my order processing for AP lic got delayed. this resulted in change of Vsz SN from X to Y now i am not to able to upgrade my VSZ and support dept of yours is asking to show me proof of support purchase for SN Y. i only have active support contract of X and i only have 1 Vsz. case no 01164661. VSZ was never reinstalled or upgraded in the past. what to do here?
