Quick Migration vs dvSwitch

Veeam Logoby YeinYein » Wed Oct 12, 2016 11:40 am

Hello,

I need to migrate VMs between 2 differents vCenter that are not using the same SSO. As vMotion/Storage vMotion will not be usable, I thought to Quick Migration.

The problem is that the destination uses dvSwitch while source use standard vSwitch. On the new vCenter, I created a Port Group in the dvSwitch with the same name as the VM Port group in the source vCenter.

But, in the vmx, the dvSwitch information uses id and not name :
Code: Select all
ethernet0.dvs.switchId = "56 02 2d 50 89 89 7b dc-28 47 81 ab 3c f3 aa 6b"
ethernet0.dvs.portId = "11"
ethernet0.dvs.portgroupId = "dvportgroup-57"
ethernet0.dvs.connectionId = "444344873"


Do you think it is possible to use Quick Migration in this case ?

Thanks in advance for your answer.

If you use Replication, rather than Quick Migration, this will let you change the target network.

Thanks for your answer but replication will generate a downtime bigger than Quick Migration.

In order to reduce to reduce this downtime I initially thought to Planned Failover before thinking to Quick Migration

Haven't tested, but my assumption is that Quick Migration should complete fine and you will be able to change network settings manually right after that.

Yes that's exactly what happened, but in a wonderful world, I (I mean, my customer) would not like to do other than launch QuickMigration and found his VM on the new vCenter

But in definitive, instead of move VM by VM, I will put couple of VM on a host, disconnect this host from the old vCenter and connect it to the new one. Then I will move the VMs by vMotion/Storage vMotion and put back the host in the old vCenter. And I repeat operations with another VMs.

I think it will be the less disruptive way to move VMs for the users

Looks like feature request.

Just so you know, this is exactly the operation I did 3 years ago for a customer to migrate from one vsphere infrastructure to a completely new one. We selected one large host so that it could hold 20-40 VMs at the same time, and within one day we were able to move 300 VMs with zero downtime at all.
