Downgrade FMG Root adom 5.6 to 5.2
Hello :)
Is there any way to downgrade FMG root adom from 5.6 to 5.2 ?
If there no way, how can i put back a cluster in 5.2.X on FMG without activating advaced adom or create a new adom ?
How can i get the policies and objects from 5.6 adom to 5.2
thank you in advance
Have a good day

Even with ADOMs disabled, in FMG 5.6 (starting in 5.6.1 IIRC), there is still an "All ADOMs" under System Settings. So you can still change the version associated with the root ADOM. This is only advisable if there are currently no devices or policy packages in that ADOM. The goal is to essentially reset that ADOM, similar to a fresh reinstall and relearn everything from the FGT through an Import. Not to preserve any objects already in the ADOM.

Yes of course the "all adoms" is still available,

If we have a backup of the FMG with Root adom in 5.2 version, by restoring it could we get back the root adom in 5.2 ? is there any loss of configuration, policy packages, objects, templates ?

Sorry, I was thinking of Global ADOM. Seems in other ADOMs we have this as a safeguard. Since in best practice, you are supposed to use ADOM upgrade.
So it looks like you either need to enable ADOMs and create a new ADOM for 5.2. Or, as you say, restore a previous FMG configuration that has a 5.2 ADOM. Of course, that FMG configuration needs to match the current FMG firmware.

Yes of course, this is the same Firmware, otherwise i will put the right firmware and restore the backup,
I need to downgrade the adom version, since when i upgraded my FGT from 5.2.3 -> 5.2.5 -> ..until 5.6.3, i upgraded also the FMG adom version to 5.6 so i can push policies and so on,
but since i performed a rollback of my upgrades on FGT i need to downgrade the adom version to 5.2
Thank you for your response and have a nice day :)
