I've upgraded two of my VMware hosts to vsphere 5.  I have two hosts remaining to upgrade.  E issue is that I don't have sufficient space to move all the virtual servers off of those hosts before upgrading.

Can I shut down the virtual servers and upgrade with them still in place on the host?

What chance am I taking on losing my virtual servers?  I have backups, but restores would take many, many hours.

Yes, you can perform an inplace upgrade, and it will detect existing VMFS partitions, when prompted, select YES to preserve. this will then not delete the VMs.

But always have a backup of your VMs before any server install change.
