I have three Extreme Network Summit 48si switches and I was able to upgrade two of them because they were running an extremeware release newer than 6.2.2b56. I have one switch that is running 6.2.2b27. It is just barely too old to be upgraded without an intermediary update. Does anyone have version 6.2.2b56 or one that would work as an intermediary update for me? Your help would be greatly appreciated!
