Updating Debian Jessie to Buster

[tarob...@gmail.com]

Hello,

When I initially setup weewx, I was very new to raspberry pi OS and so I used what I had currently had on hand, a RPi I got a couple years ago which was running Jessie. Recently, I've realized there are some issues, mainly Python2.7 and Python3.8, that basically boiled down to running Jessie vice the new Buster. If anyone is wondering, the SSL module was having issues installing updates via pip command and it came down to the OS.

Anyway, I plan to create a new SD card with Debian 10 (Buster) and then install weewx. I've read upgrading OS from Jessie to Stretch to Buster could take quite a bit of time and there is a risk to losing data. My question comes, what's the quickest way to get weewx running, as it is configured now, on the new OS? Ensure I backup my weewx.conf, weewx.sdb, and skins? Is there anything else I should be conscience of when moving? Is there an "easier" way to do this? Just worried I'll be down for a while trying to configure and get everything up and running as it is now.

Thanks,

Troy

Set it all up on spare hardware. If you don't have spare hardware use a vm. That way you won't be down while you work out any issues.

Good idea, I don't have spare hardware so I'll have to setup a virtual machine. Although this maybe an excuse to go ahead and pickup another RPi.

Always easiest on a pi to just swap in a new SD card, install the os, and reinstall/reconfigure weewx+skins based on a 'copy' of your original working setup with the earlier version.

I wouldn't think you should be down too long unless you have a lot of manual customizations that you don't remember having done any more....

But you're on the right track for sure...

HI Troy

I did something very similar awhile ago and didn't have any issues.

As Vince said "use a new sd card to build the new system"

What made my transition easy was the weather console has a memory that holds approx several days of data.

If I stop weewx for some reason and for some hours, then restart it, weewx appears to retrieve the missing time interval.

This helped by keeping the original database intact.

The new sd build database would be discarded when the new sd card was finished.

So over a few days I just swapped between old and new until I was happy with the new setup.

Then just copied over the files I wanted .......just mounted the old sd card on another pi and copied the files over.

regards ian p

Thanks for the advice. I am running weewx with SDR, so no console to store data. Although I have an acurite access which is still collecting data so I can use that data to fill in any gaps I have while transitioning. I think if I just back up my weewx.conf, my skins, and weewx.sdb I should have everything I need. Plus getting the BME280 pressure/temp running on the new pi and all the weewx extensions I have (BME280, forecast, and SDR).

So I've finally got around to getting a new Pi loaded with Buster and installed Weewx using python3, all the extensions, and skins. The final part is moving my weewx.sdb and I want to ensure I do this properly. Would I just be able to stop weewx, copy over weewx.sbd (all historical data), and move it to the new Pi? Then start weewx on the new Pi? Or is there something else I'll need to do? Thanks.

Sigh - doesn't anybody read the 'years' of the 'many' times people have asked the same questions ?

No, there's nothing else you need to do.

Thank you Vince.

I do... did... was skeptical... got over it.... Verbatim copy
worked for me. Hours of painful research confirmed!
