Thanks for the recommendations.
Now, using "migrate_server" is 100% mandatory, before executing a version upgrade of your GAIA OS?
In our environment, we have 1 SMS in R80.40 version, and another SMS for another site, in R80.30 version.
We need to bring it urgently, to R81.10 version, but the idea is to use CPUSE to upgrade the MGMTs.
I understand that "migrate_server", is to have a "Backup" of the rule base, in case "something" breaks during the upgrade, is that correct?
Both versions, R80.40 and R80.30, can jump "direct" to R81.10, in the SMS, using CPUSE, right?
Regards.
