network core change

[doug_hamp]

We are switching out all of our core switches this weekend (from cisco to HP). The current hosts have no redundancy basically one nic to a common switch. I have added a 4 port network card to each host (4) and pre-configured vSwitches (2 ports for mgmt, 2 for vm network, etc). The 10G iscsi ports & cables to the SAN will not be touched.

My question is when moving to the new core switch can I simply connect a new cable to a new vswitch vm network port - let it sync & then remove the current cable?

As I understood You are replacing core switches, so the access switches (top-of-the-rack) and their configuration is not changing. Right?

If Yes, so You dont have to worry if You taook care to properly configure core switches to interoperate with access switches.
