Upgrade Domoticz 2.5 (Pi B+) to 3.8. (Pi 3 B)

[amercat37]

I would like to upgrade my Domoticz server from version 2.5 on a Pi B+ to the latest version on a Pi 3 B.
I've read a bunch of forum post and it seems that i could go about this three different ways.

1) Take out the micros SD and place it in the Pi 3
This will not update my OS and I just don't like this idea.

2) Install Stretch and Domoticz on the new Pi and copy over the domoticz folder from the old Pi.
I like that fact that this will copy over all of my scripts and floor plans.
However, does this mean that when I start Domoticz on the new Pi that I will be on version 2.5 again because I copied everything over?
Are there any other incompatibility issues with copying everything over?

3) Install Stretch and Domoticz on the new Pi and then use the GUI to backup/restore from the old Pi to the new Pi and copy over scripts and floorplans.
This seems like the most common way, but is the backup/restore fully compatible between versions? It seems too simple.

Just looking to see if the are any pro's or con's to each way and if there is an officially approved way to upgrade like this.

Thanks.

What os version are you on?

My old Pi B+ is on Wheezy.

Hi,
I had similar issue too:
I tried several times to upload my backup made on beta 3.87XX running on Jessie onto fresh stable install made on Stretch with no success. Is there an compatibility problem?

They say you should NOT go from beta back to stable. I've done that, however, the result after some time was database malfunction. Stil working, but there were some issues cleaning the db, for example.

I've couple of times changed Raspbian version, Raspberry Pi, etc. and my thoughts are:
- backup Domoticz db
- copy whole Domoticz folder
- upgrade/ change the card/ change the Raspbian version/ change Raspberry
- restore db
- copy missing files (scripts, floorplans)

Should work.

But, to be honest, why don't you just try? The only thing backup does is copying whole db to your computer, restore just puts it back and restarts Domoticz. THE ONLY issue I had were plugins. They are generally not stable in Domoticz. After switching them off, all the backups, restarts, are fine.

Thats the point - plugin. Im trying to get back broadlink plugin to life (tried everything, stable, beta...), but no way to keep it alive on jessie. As soon I enable it Im loosing connection to domoticz via browser after first reboot.
I was able to run it on stable stretch, but no success to upload db
And I did even this - fresh install on jessie and downgraded to stable - backup and then tried to upload ion stretch. But after upload domoticz stays always empty

I've quit using plugins because of stability issues. Great loss, as there are some interesting plugins that improve Domoticz a lot! E.g. Polish Airly or Storm report.

So after much reading, pondering, and debating with myself, I decided to do a fresh build and import the database.

Pi 3 model B running Stretch
Fresh install of Domoticz
Imported DB and copied floor plans and scripts.

The only think that I couldn't get working was Mochad for my X10.
So I left my CM19a and my Aeon ZStick on the old server.
I've decides to just replace all my old X10 and maybe ZWave with Hue, Sonoff, and TPlink, etc.

So I temporarily have two Domoticz servers running which reference each other with json calls and both are 100% stable and functional.
Now I just need to decide on cheap switches, lights, relays, outlets, etc and slowly transition.
I did purchase some Hue bulbs and switches and they are awesome. Thinking about TPLink for wall switches and plugs and Sonoff for relays.
