Upgrading cluster 6800 from 80.40 to 81.20

[khusant]

Planning to upgrade management VM and 6800 cluster from 80.40 to 81.20. Tech support says I can upgrade directly, no need to install intermediate versions.

Can someone who has done that confirm that I can upgrade directly?

Also TAC suggests upgrading to R81.20 Gaia Fresh Install and upgrade and then install Jumbo hotfix.

And what version is more stable 81.10 or 81.20 ?

You can upgrade directly from R80.40 to R81.20. R81.20 is currently our recommended version and is showing good stability.

For more information on the upgrade procedure, please see the admin guide.
