  1. Normally downgrading F5 is sort of performing a fresh installation and reverting software back to an older version. And Unless you have a UCS archive file that was generated on the version to which you are downgrading, you must manually rebuild the F5 configuration after you perform a downgrade. 
  2. But in your case, your F5 were already running on older version and it is already present on other boot location. So this will allow you to revert back to older software version and the configuration by rebooting F5 from the partition containing the older version. So you just need to reboot F5 from HD1.1 boot location and you should be good. Still have configuration backup/UCS of current version in place.
  3. As per below article, you may require to reactivate license reactivation. And the version that you're running on are having some changes in licensing behavior. So its better to reactivate license. Otherwise the F5 will not be active/operational until you reactivate license.

Hope it helps!

    Reason i asked Activation question because this box is in lab and nobody has any idea about licensing, Let's assume we don't have active support in that case am i going to be in trouble to switch boot image? I don't care about configuration because its in LAB.
