Quick question on firmware upgrades. I'm mainly a cisco data guy but have some nortel switches I end up helping with as well.
When upgrading firmware and diags on 5520 switches specifically I was told by another tech you have to go though installing all the releases/diags in order one at a time until you get to the latest you intend to use. In the cisco world you just push the IOS verion you want with no in between updates. Is the above steps required or can I just upgrade to the latest firmware/diags in one shot?
Thanks!
