Updating PHP for an older version of cacti?

[jtzako]

I have a fairly old cacti server that I need to do a few updates on, including updating PHP. The server is on php 5.5.38 and cacti version 1.2.12. I need to update php to at least 7.3.24 but am not sure if this older version of cacti will work properly. Anyone know if it will be ok?

On https://github.com/Cacti/cacti is table with supported versions.

It should work. We recommend update cacti to 1.2.26. It was released few days ago
