Hi,
The upgrade should work fine from a browser, i recently upgraded one of my switches.
Configuration should remain the same after the upgrade.
However, SRW series tend to have some problems, so:
- backup your configuration before upgrade (it's best practice to always backup all configs before any upgrade on any switch)
- have a serial console ready with Xmodem software, in case the upgrade goes bad...
Cheers,
Tamas
