Hi all, is there a difference between physicly unplugging a switch and using the reload command ? By difference I mean maybe some important pre-reload process that occur when I issue the reload command.
I ask this question because I have to upgrade many many 3550 (critical production switch) from 12.1.13 to 12.1.22. There's a scheduled blackout in our building so my strategie is to erase current ios version from flash, download ios 12.1.22 on all switch flash couple days before the blackout, configure boot system and wait the blackout. When power will return, all of my 3550 will run 12.1.22.
Should I espect some problems ?
