vCenter Migration from different SAN's
We are in the process of getting a new SAN installed and are wanting to migrate over the old VMware Hosts to the new vCenter Server.
We have a total of 3 vCenter Servers. One new, one production, one test. We want to Migrate everything off the old vCenter servers and onto the new.
My question is best steps to go about this. I plan on following the guide in the link below.

I believe I'll need to connect the old SAN network to at least one of the Hosts on the new vCenter Server.
I can then Migrate the VM's to that Host once the hosts are added to the new vCenter server from the old vCenter server.
The test is local storage and no SAN, so that should be just a migration over the network once hosts are added, or would there be additional steps?
Thanks in advance!

The problem is we have a 10GBe on the new SAN and 10GBe SAN switch. We don't have any 10GBe cards to install on old Hosts. Is it possible to not connect old hosts to new SAN switch but connect New Hosts to old 1GB SAN and still do the migration?

I was also wondering if Local Storage on test hosts would be a problem for migration?
A host needs to have access to both datastores.
You can migrate from local storage to SAN.
You can migrate from local storage to SAN.

The information provided was not 100% what we needed. Reached out to VMware and there are new features in 5.1 that allow sharing between datastores even if the host isn't connected to them all.
Datastores are connected to Hosts.
vCenter Server is used to manage the hosts, and complete the migration.
Virtual Machines are located on datastores, and registered in the Host Inventory, vCenter Server displays this Inventory.
VMs do, not run on vCenter Server, or migrate to vCenter Server, vCenter Server is just a management tool, for completing functions across hosts in your inventory.
So providing that A host has access to old and new datastores, you can migrate the VMs between datastores.
If you have Storage vMotion you can do this live.
