Nexus1000V - Migration to new VCenter

[hleschin]

Hello,

in the past it was always a problem to move ESX-Hosts with n1v to a new vcenter. The only possibility was to migrate all hosts/VMs back to vswitch before, what's a big effort in large environments.

The procedure to do that was already discussed in this community, for example here:

https://supportforums.cisco.com/thread/2119884

However, it was not only a problem with n1v. VMware DVS switch had the same restriction.

But with VCenter version 5.1 VMware had a new feature implemented to avoid using the vswitch for such a migration, see here:

http://www.ivobeerens.nl/2012/10/29/migrate-to-a-new-vcenter-server-with-the-vsphere-distributed-switch-vds-enabled-in-vsphere-5-1/

It's like an Import/Export function for DVS information and it works only for VMware DVS switch.

What's about n1v ? Iwatta wrote in the thread (first link) that cisco is working on a solution for n1v too. What is the current status about that?

Hendrik,

Still no changes in the process for migrating to a new vCenter.

You'll need to migrate to vswitch, move to hosts, reconnect vsm, add hosts back to n1kv.

Louis,

is it planed to implement a solution for n1v ?

It would be very,very helpful. One of our n1v environments has for example 62 host in one DC with ~800vnics. All this have to me migrated to vswitch and , after the move to the new VCenter, back to the n1V. It's really a big effort.

And my VMWare colleagues are not happy about that. Especially because VMWare has now a solution for their own DVS I think there should be also a solution for n1v very soon.
