NOS 7.3.0aa downgrade - is it safe?

[Pawel_Eljasz]

hi everyone

I wonder if any of you have done downgrade from 7.3.0aa?
7.3.0aa is that peculiar release where you loose config after upgrade to 7.3.0aa from previous version.
If you have done downgrade was everything okey? Did you not loose configuration?

many thanks, P.

I learned of it hard way, here: https://community.extremenetworks.com/data-center-slx-vdx-mlx-ces-232983/vdx-6740-firmware-upgrade-fails-issu-is-not-supported-to-the-target-firmware-version-7822836

So downgrade does the same, wipes the config clear, okey.

Maybe it's okey to wait for next average-user release, since config recovery will be need either way, no?

Pawel,

7.3.00aa was designed to only be used by the Federal Sector. In order to upgrade/downgrade to this version you are required to default the config.

If you have moved to this version and have lost your config, this is expected and working as designed.

We recommend the average user to remain on 7.3.0a and bypass this build.

Thank you
