I have to upgrade from R77.20 to R80.10.
SMS is virtual in Vcenter
Gateways are openserver fisical.
The procedure for the SMS that i have thought is this:
-Get a migrate export in R77.20 from customer .
-Mount a VM with R77.20 and do "migrate import" of previous step.
-Use the upgrate tools for R80.10. What tool i need to use in order to migrate config R77.20 to R80.10?
-After generate the backup in R80.10, i will create a new VM installing R80.10 iso and will import the backup in R80.10.
-When i have to run the upgrade verify?
Thanks a lot
