New License Keys
Requesting new passwords for existing licenses
If you are an existing Data Protector customer, in order to upgrade your old license passwords to version 9.00 of Data Protector, you must have a valid active support agreement in place, covering the quantity and types of licenses you have in use.
Once you have received the new license keys, you should compare them to the quantity and type of license keys installed in your Data Protector environment. You should upgrade the software the software only after you have verified that you are in possession of enough valid HP Data Protector 9.00-based license keys.
If you have received fewer or different new license keys than there are actually installed in your Data Protector environment, you should not upgrade to Data Protector 9.00. Otherwise you risk that your Data Protector environment is no longer operational due to missing license keys.
Instead, you should contact your HP sales representative or HP partner first to determine what steps are needed to close the gap in the licensed functionality covered by your support contract and the actual licenses currently in use with Data Protector versions earlier than 9.00.
