Do all MHOs need to be upgraded before starting the SGM upgrades?

This is the correct answer because it follows the upgrade order and procedure specified in the R81.10 and R81.20 Administration Guides for Maestro environments. The MHOs are responsible for managing and synchronizing the SGMs, so they must be upgraded to the target version before the SGMs. However, the SGMs can be upgraded one by one or in batches, as long as they arecompatible with the MHOs. The upgrade process also supports Multi-Version Clustering, which allows different versions of SGMs to operate in the same Security Group with zero downtime.
