[ovirt-users] Global maintenance and fencing of hosts

I am wondering whether global maintenance inhibits fencing of non-responsive hosts. Is this so? Background: I plan on migrating the engine from one cluster to another. I understand this means to backup/restore the engine. While migrating the engine it is shut down and all VMs will continue running. This is good. When starting the engine in the new location, I really don't want the engine to fence any host on its own, because of reasons I can not yet know. So is global maintenance enough to suppress fencing, or do I have to deactivate fencing on all hosts?
