KBOX K1000 Upgrade to 6.0
I've got the following scenario:
Two K1000s both at the same version (5.5.90548). One K1000 is for production, the other is for testing.
I'd like to restore the backup from the production server to the testing server and then upgrade the testing server to 6.0.
Once the upgrade completes, am I OK to change the IP and system name of the restored (testing) server so as to confirm that everything is working OK while still using the production server in production? After confirming that the restored server is good to go, I'll take the production server down and change the IP and system name to what the production server was and begin using it in production.
Make sense? I do understand that any changes to the production server while testing the upgraded server will not be reflected in the upgraded server.
The main reason for doing this is because I have a very large device count (45K+ and growing). In the past upgrades have taken a very long time and I don't want to take the production server down for that period of time. Also, if there is an issue with the upgrade, I'll still have the production server to fall back on.
