Hello,

I have an environment with two data centers with some clusters in each one. Each cluster has one or more dedicated FC storage domains.

We have some management problem because adding storage to one cluster means to add it to all nodes of all clusters in the same data center, by the way I found this a little overkill and I think it should be managed like networks.

Anyway, to resolve out problems we would like to create a new datacenter and move a cluster from old data center to the new one, obviously with it's own storage domain.

Is there a way to do this without export/import all vms?

If you allow a downtime, the simplest option is to detach your storage domain (you cannot detach the storage domain if it is the last available cause you always need a master storage domain within your datacenter) from your old data center and attach it to the new one once you created a new cluster and you migrated some hosts here.
 

Thank you.
