Migrate esx cluster with multiple EQL from Force10 stack to N2000 lagged setup W/O downtime

We currently have 5 servers connected to a S25 Force10 stack with 2 PS6100 and a PS4000. We will purchase a PS6210 (prepare for future 10GB) and want to add it to the cluster (on 2 x 1GB)

Since the S25 withes are 24 ports and in a stack, we will also purchase 2 N2048 switches and put them in a lagged configuration (with the 10GB twinax on the dedicated ports).

I am wondering what the best course of action would be to migrate the 3 Equallogics and 5 servers to the new switches.

My first idea, is to connect the S25 stack and the N2048 lagged setup with 4 or 2 1GB cables and put these in a lag as well. Then I can simply switch cables one by one.

Not sure if this can be easily configured on the S25 though. Anyone any ideas or tips?
