VMWare standard to distributed switch migration

Hello EE,

We have VMWare 6.5 and were asked to add a VLAN to our distributed switch.
It appears we do not have any distributed switches setup, but only standard network.
What would be the migration process and can a distributed switch be brought up side by side - without any outage?
I am struggling to find anything online to guide me

If you have standard switches, why don't you add the VLAN to your standard switches.

You can create your Distributed Switch design and configuration, without any downtime to existing vSwitches, providing you add new UPLINKS in the host.

There will be downtime, if you re-use existing uplinks attached to current vSwitch.

AND when you disconnect from virtual machine groups, using standard switches, to virtual machine portgroup used by distributed switches, technically there will be downtime, as the traffic learns a new route...

which should be just several pings....

So are they in essence the same other than the standard is a few more steps?
As I understand it is one per host for that and the distributed goes across all.
Thus it doesn't matter which we use if we need to add a VLAN it would work the same to add it to our standard?

Standard vSwitch are per HOST, so same configuration needs to repeated per host.

If you have many hosts, trying to keep network configuration the same across hosts can be tedious.

If you have many hosts, the same network configuration is applied across all hosts, so one networking change applied to many.

If you have the licenses for Distributed Switches, understand networking, and have many hosts - it's worth a look at Distributed Switches, there are better load balancing and network features.

BUT that is not to say you cannot use VLANs with Standard Switches.

At present, it's probably quicker to add this VLAN per Host.... because Distributed Switches, requires some design.
