Migrate from 1.8.17 to the latest stable version


Tell me the best migration path. How to do it right? Is it possible to fix the configuration file immediately for the new version?


To upgrade to a newer version you can test your config in a preprod or dev env. If it’s not possible, you can try to deploy your config within a docker.

Otherwise, you have to upgrade, make a config check ( haproxy -t -c ) and debug/update your config.

Before all all this, you can have a look on the deprecated feature/config on the release notes for each intermediate version.

Thanks! I will try.
