Can anyone tell me the correct way to upgrade the dual supervisors on my cat 6500, and will I have to have some downtime to do this ?

I have this problem too.

Definitely, you need to schedule a maintenance window, this is a major change.

The best way for you to upgrade the IOS is to have the standby chassis upgraded first and once it is completely done shift the traffic to this chassis. Upgrade the other chassis afterwards the same way as was done on the other chassis.
