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