I am going to upgrade the VSS license on WS-C4507R+E . The below Cisco document says to shut down all the non-ISL link, install the license, then shut the VSL link and reboot the primary switch. There will be more down time and might need the console in case the VSL didn't come up. Is this a good idea?

Instead of that, the below plan will work? Please suggest.
4500-X#copy tftp: bootflash:
Upload 2nd license file to Secondary VSS flash file
4500-X#copy tftp: slavebootflash
Install license on primary VSS
4500-X#license install bootflash:LICENSE_FILE_NAME.lic
Confirm image level after reboot.
4500-X#show license image levels
Now we will shift control over to secondary VSS device.
4500-X#redundancy force-switchover
This will reload current switch and shift control over to secondary device.
Repeat the above process by installing 2nd license file and reload this device or forces witch over. Once this device comes up, you can move control over to it in order to double check what image level it booted from.
Thanks,
Manu
