Raspberry pi model b rev 2 (OLD MODEL)

Hello, I have a question, and I would like opinions…

I currently have a second zigbee2mqtt server running on a raspberry pi model b rev 2, with version 1.16.1 and it works great for me, it is my second server and it is installed in the storage room and it perfectly manages 5 sensors, 2 door, 1 bulb one for vibration and one for temperature and humidity, now I want to add a plug of those that measure consumption version and surely it will not be recognized, my question is the following… will this hardware support the update to the most recent server, if so How should I do it so as not to lose what I currently have configured… THANK YOU!!!

Sorry, I forgot to comment that I obviously have it integrated into HA with a different topic so that the two servers work separately and each one manages its sensors. The other server is at home on another more modern raspberry 3B+

You are way behind on the versions. The current version is 1.32.1 - you are not on the new repository.

I know, I have another one updated without problem on a Pi3b+ but my question is, will the new versions work on the old raspberry??? You can do a clean installation for the new version and keep the old one in case it is not good to go back to the one I currently have, which is perfect for the 5/6 devices that I use

It should handle the update fine - Z2M is not particularly hard on the CPU/RAM.

Ok, and to do it? Would the manual on the developer’s website be followed? How can I know which option I have installed? I think I installed it on Linux, not in a virtual environment or anything strange. Thank you!
