If you consolidate your QuarkXPress licenses into a Quark License Administrator Multi-Pak ,your old serial number(s) will be voided. You must uninstall those QuarkXPress licenses, including your dual licenses.

Organizations that have 2 or more copies of QuarkXPress® or QuarkXPress Passport® software can consolidate their serial numbers into one parent serial number (Site License). All copies must be at the same version of the software. If all or some copies are not at the same version, you must upgrade them before you can consolidate
