Hi,
As I have an existing 6500 which needs to migrate the existing Sup720 to a new sup2t supverisor engine on the same chassis running VSS; I was wondering if there may be any suggested/recommended approach besides backing up the Sup720 configuration and rebuilding it on the Sup2T from scratch.

Any suggestion is appreciated.

Can you just backup the config to your 2T with the compact flash card? I believe the 2T has a compact flash type II drive.

Hi,
Apreciate for the information. As I am new to migration using the config to copy to the flash card; will the sup2t be able to migrate the config on the existing Sup720 to the new sup2T? I would understand that the sup2T would run a different version than  the sup720 (the configuration may be different on sup720 and sup2T such as the default class-maps and copp/etc...) and the port configuration on the supervisor engine is different on the sup2t.

Appreciate in advance for the reply :)

I tftp the config of the 720B to my PC. Then tftp it to the Sup2T. I had some static routes and the SUP 2T added some new ones that causes a few errors. But if you understand your config very well. Then, tftp the config to the Sup 2 T should not be a problem. I did the stand alone migration though, not VSS.

Hi,
Thank you for the weblink on the cases scenarios. That has really been very helpful (I was intending to open a TAC case and have them on standby, but now I can do it myself instead as I know the expected behavior).

Appreciate for the great help :)

I strongly advise that you still open a TAC case and have them on the standby. With those high end switches, you always schedule a Cisco TAC engineer when you do an upgrade because you never know. Weird things can pop up, especially the 2T. Thx
