Check out the following link; it talks about "high availability" and "versioning."
I've not had a chance personally to try the "versioning" support to perform an upgrade but I think this might be what you're after... http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_6_2/confg _gd/redund.htm#23097 If you have a chance to go through this procedure, let us know how well it works.

[7:51508] I have a 6513 with redundant sup modules and I'd like to update the IOS image. Is it possible to do this while remaining mostlly transparent to users on the switch? I've read the instructions on CCO and according to them I'd still have to reload the entire switch. Is it possible to do one engine at a time while the other is running as primary?
