Upgrading Duet2 Wifi from v1.19 to 3.5.2... questions

vbtalent2

So, I've been out of the 3D printing scene for a while. I want to get back into it and I'm looking for a little insight into upgrading my Duet2 Wifi with firmware 1.19.

I've been trying to read up on the migration path for upgrading to the latest firmware version and it seems quite complicated... to say the least.

Is there a path for exporting the data from my current config file, which I have to find, installing the latest version 3.5.2 and then modifying that config file for my current setup?

Is there a better opportunity to just start fresh but be able to glean my setup information and migrate/update that into the 3.5.2 config files?

Any insight would be appreciated.

exporting your current config is easy, just take the micro sd card and make a copy of that on your computer.
the most direct way to go from venerable 1.19 to 3.5.2 is to reflash the board using BOSSA. https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#fallback-procedure-2
if I were in your shoes, Id use the reprapfirmware configurator to create a new config from scratch, using the old config as reference for the printer information https://configurator.reprapfirmware.org/

Asking a followup to the creation of a new config file using the tool... looking through my current config file and I notice there are a number of items that are listed there but not identified in the config tool, is this because they have been deprecated and only the relevant items are in the tool now?

For instance...

I have a line in my config "G21; Work in millimeters" but in the config tool I do not see and option in the general section to set that.

@vbtalent2 it's set to mm by default so G21 can be omitted. You can also manually edit the config afterwards using notepad. The config tool isn't designed to create a perfect config, just something near enough
