We are finally getting our 10+ year old 6509 replaced for our main switch. We are doing it in stages and trying to minimize downtime. So right now I have the 6509 up and our new switch connected to it with a 6-1Gb LACP between them tagging vlans. The 6509 still has all of the vlans with the ips (gateways). The main thing connected to the new switch are our servers with Iscsi drives and our NetApp San. Correct me if I'm wrong but if a server on our vlan 4 is going to talk to a different server on vlan 5 or storage on vlan 6 the traffic would start on the new switch, go out the 6 port lag and then back up the lag to its destination on the new switch? I want to fix that as my next step so I think I need to move the gateways for the vlans and put those ips on the vlans on the new switch. My question is how would I do this? The 6509 is still the main hub and I'm trying to figure out how user traffic would know about the gateway move. Is it easy as moving the ip on the vlan? Would I leave the vlan on the 6509 or just get rid of it if I have no more servers connected on the 6509 and remove that from being tagged on the lag between switches? Sorry if I'm asking a stupid question... Running on 4 hours of sleep after a large project last night! Thought I'd ping the community to make sure I'm not crazy.
