Did you guys clone your FV2 encrypted HDD to the SDD (or did you decrypt first before cloning)? If you did, did you experience any problem when upgrading the OS? I couldn't boot after trying to install an upgrade. After restoring from Time Machine, I also found that I could not turn off FV2 since "The target disk isn't eligible for reversion because it wasn't created by conversion or it is not part of a simple setup of exactly one logical and one physical volume." I didn't set up any partitions.
