I need to replace a couple of SUP1As with SUP2s and could use some advice on the best method to proceed. From what I have read here and elsewhere, it seems the best method is to stage a SUP2 in a spare chassis and apply the configs beforehand. Then, the migration would simply consist of swapping SUPs. I would like to know if this is the best course of action. Also, as to copy configs, would it be preferable to copy the configs to a flash card in my test SUP2 and then just insert that flash card into my new production SUP2. Or, is it better just to use the actual SUP2 I built in the lab. Is there a difference?
Your help is greatly appreciated.
