Hello!

I have a TL-SG2008P jetstream switch and would like to perform a firmware upgrade on it.

However, I have a few quick questions as I need to verify the following:

- Can I upgrade directly from original firmware to the latest one (https://www.tp-link.com/de/support/download/tl-sg2008p/v3/#Firmware) ?

- In case I've created vlans and acls already on the switch, should I first reset everything before I make the firmware upgrade? I ask coz I've read somewhere on the forum that someone had issues with the new firmware showing weird characters (like dashes) for settings it couldn't take..

- will my settings be erased?

- lastly, my switch GUI has a section called "Controller". I have it disabled by default. What is this controller setting? I assume it is an option to link up with some other device which probably is the "controller" I guess. Or is my switch the controller? The confusion comes from the fact the device page online has a "Controller Software" updates section separate from the firmware updates section.

Excuse me, I'll get there! Have a good one:)
