If there is a incompatible host attached the upgrade will not be allowed to proceed. Prior to upgrading we also need to verify that all hosts have been upgraded to vSphere 6.7 so we do not have any errors. To take these considerations into account, we will make sure to include this in our Upgrading your Virtual Distributed Switch automation. Some of these considerations are making sure to put DRS into partially automated mode since if a vMotion occurs during the upgrade the VDS upgrade will fail.
This KB covers considerations around known issues upgrading to version 6.6. Prior to upgrading our VDS version to 6.6 we definitely want to make sure we review KB52621. A question I get asked quite frequently is why is vSphere 6.7’s VDS version 6.6? The answer is quite simple, VMware on AWS (VMC) shares quite a bit of the same code as vSphere On-Perm and since there were no major changes to the VDS features or functionality the version stayed the same. With vSphere 6.7 and the introduction of VDS version 6.6 there are some known issues and considerations I want to mention prior to getting started upgrading our switch. The VDS upgrade is also something that has no rollback, once it is complete it is permanent unless you have completed a backup. Previously in most vSphere versions it has always been said that upgrading your VDS can be done at anytime and is a non-disruptive upgrade., but we always want to use caution and do this within a maintenance window. If you run any nested virtualization in your environment this is a great enhancement as we no longer require you to enable promiscuous mode on your VM port group.Īnother consideration I like to recommend is that you keep your VDS upgraded to the same version as your ESXi hosts whenever possible. We can see that upgrading to version 6.0 gets us NIOC v3 and IGMP/MLD snooping, version 6.5 gives us port mirroring enhancements and version 6.6 gets us mac learning. Another reason is that we can review the new features that are listed below, we can see this when we click on the (i ) within the VDS GUI. The first consideration we would like to think about is why would I want to upgrade my VDS? Well if you had previously upgraded from vSphere 5.5 your VDS still may be on version 5.5 and this is not compatible with vSphere 6.7. Considerations for Upgrading your Virtual Distributed Switch Please make sure prior to upgrading your VDS to 6.6 all ESXi hosts have been upgraded to ESXi 6.7, if you still have hosts on ESXi 6.5 you will only be able to upgrade to version 6.5.
When upgrading your VDS on vSphere 6.7 the version is actually 6.6 (we will cover the details later). The final step of completing our upgrade will be upgrading our Virtual Distributed Switch (VDS).
