SOLVED Downgrade from 9.10 to 9.3

[dreamerns]

I updated freenas to 9.10, but then I realized that my manual jails are not working anymore (can't install new ports). I understand that the only solution is to wipe all my jails and start from scratch, but I have many of them (8) and to configure them all from scratch is going to take lot of time. So, my question is it possible to downgrade back to 9.3 (System->Boot, select last known good configuration with FreeNAS9.3 and activate it)? Did anyone tried that?
Also, if my only options is to wipe jails, I see lot of people are doing it like it's nothing. Am I missing something here, is it possible to somehow backup plugins data and load it back in new jail in some universal way ? I saw couple of suggestions for plex, but what about other plugins like owncloud and etc?

Thanks.

It's certainly possible. Note that the config in that environment will be the one that existed at the time that upgrade was done. If you've done any significant changes since then, you'll have to restore the 9.3 config from a backup.

Seems to be working, only have some issues with transmission plugin, but that one is easy to redo from scratch
Now I have time to create strategy for updating to 9.10
Thanks
