Performing EUD Upgrade

Question

I'm having same issue like https://devcentral.f5.com/questions/bigip-1022-hf3-config-sync-problem and plan to upgrade EUD upgrade from version 12.8 to 12.2. (LTM3900)&nbsp;
I need to confirm few things.&nbsp;
1) Can we upgrade just one unit peer unit ?
2) Can we downgrade back the EUD after we upgrade?&nbsp;

You can upgrade one unit peer only.&nbsp;
EUD is an offline utility run only at appliance startup by choosing "End User Diagnostic" in Grub.&nbsp;
If you want to downgrade EUD, you can install it on a USB stick and boot on it at appliance start.&nbsp;
