Hello,

first of all, you have to check the release notes to see if any changes could broke your config.

After that maybe you can try your config in docker env.

Regarding the build, i would test in preprod or dev env before trying to do it in prod. I’m not really into building from source, but you should be able to build in a build directory before replacing the current bin with the new one.
