Re: Distributed Switch
If both host make part of the same vDS, I presume they are, the VLAN exist on both hosts, but the problem may be on the physical switch configuration. Please check if the host where the VM has the...

You can use vDS health check to confirm there is no configuration mismatch. It is possible that you have VLAN mismatch or your portgroup vlan tagging is misconfigured.

All,We have 3 exchange servers hosted on 3 ESXi hosts in vCenter_A environment. We have another ESXi hosts in other vCenter_B environment.So there are 2 different vCenter environments. We need to merge...
View ArticleRe: Host migration without downtime
You can disconnect esxi, remove it and add it to another vCenter without downtime to the VMs. This will not impact the VM unless of-course you are using vDS which is dependant on vCenter.
