Updating from VERY old build

What is the problem?

I turned on my printer for the first time in 3.5 years and my OctoPrint 1.4.0 using an RPi 3 booted just fine. It's (obviously) just incredibly out of date. I tried updating through the update function in OctoPrint, and it was failing. I decided to make a backup, replace the board with a RPi 4 and started with a fresh image from the Raspberry Pi Imager (as suggested) and then tried to restore the 250MB backup I made and it keeps failing with the below errors:

Error while running restore

    data = self._decompressor.decompress(data, n)

Restore failed! Check the above output and octoprint.log for reasons as to why.

What did you already try to solve it?

I have researched and it looks like someone in another thread suggested upgrading to 1.7 and creating a new backup and starting from there. I found instructions and used the following command:

~/oprint/bin/pip install --force-reinstall OctoPrint==1.7.0 --no-cache-dir

but after a little bit, I get the following error:

Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

I'm Sorry but it looks like this started in 1.6.0 and I'm trying to get there. :slight_smile:

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

Working version:
Raspberry Pi 3B running Buster
Octoprint: 1.4.0
OctoPi: 0.17.0

Trying to install the image from Raspberry Pi Imager (1.9.3) on a Raspberry Pi 4 and then restore the backup from the above
