Upgrading distributed virtual switch from 4.1 to 5.1 operation mode

VM-Masses,

I'm just about done upgrading one of my clusters to 5.1.  I have a vDS that was created when the cluster was initially installed.  All of my VMs, including my VCenter run under the vDS.

My questions are:

What will break when I click that upgrade link?

Will my cluster experience any network downtime?

Should I build a new vDS and try to migrate?

My environment is 2 Cisco UCS Blade Chassis (13 Hosts)

Each blade has 2 adapters defined and uplinked (10G) in passive/failover to the dVS

Storage is all NFS (netapp)

Have any of you experienced an upgrade of your vDS's?

I'd love to hear your experiences.

Thanks in advance,

Brian

Upgrading vDS is just a 2 step process but beforing upgrading to vDS make sure that all your host are running ESXi 5.1 or later and then proceed to upgrade

My migration did not go so great. I went from 5.0 to 5.1.  Post migration deploying new machines failed to associate to the interfaces properly. I also had issues when starting up pre-installed vms asking if they were moved or copied, as if it was a brand new install.

I decided to build a new VDS from scratch with the same portgroup structure as my previous, and then migrating from the old VDS to the new one. That worked.
