Hi,
My current environment have 6 ESXi 5.1 host in a cluster with HA, DRS and Storage cluster with DRS enabled. I'm planning to move the host to new Vcenter 6 for the host to be upgraded and after host upgrade the distributed switch version will be raise to version 6. I will be switching the DRS to manual before remove from the old vcenter.
What about storage cluster and storage DRS?
Is there any downtime when performing distributed switch upgrade?
