I'm currenty upgrading a cat4506 switch

and I'm trying to remove the old vlan files. The delete command but it's still there. Basically, I'm upgrading the sup mod from a production switch with a spare. I was able to get the IOS and config over via removeable flash.

However, the spare sup was a used moduled and it has old config.

can anyone please assist if they know how? thx

Change the vtp mode to transparent then do a write erase on the switch and reload the box and it should wipe out those vlans.
