6509 Upgrade

[xdxml12]

We are purchasing a second core switch and want to have them in a VSS cluster. Both 6509. However- the old 6509 has an older sup and we are upgrading the sup as well to the sup2t. Can we upgrade to sup2t without restating the 6509?

To minimize downtime as much as possible. This is what I had in mind and would appreciate any input.

1.Setup new switch with hsrp and vss.
2.Ensure root bridge is still the old 6509, and using rspt.
3. Connect switches together
4. Remove old switch, should fail over to new switch
5.Upgrade old switch
6. Turn off hsrp on new switch
7.Turn off hsrp on old switch
8. Enable vss on second switch
9. Connect old switch back in

Any advise or comments or pitfalls I need to watch out for?

Thanks in advance.

Hi,

I have never tried to upgrade the supervisors while running so you can give that a shot and let us know how it goes. Alternatively, since you are taking it out of production you can save the config, power it down, replace supervisors, power up, copy config to new sups without any issues.

I would also check to make sure all line cards will be compatible with the new sups.
