The cmk-migrate-http command-line tool is removed in Checkmk 3.0. If you haven't migrated your 'Check HTTP service (deprecated)' rules to the new 'Check HTTP web service' ruleset, you need to do so before upgrading to Checkmk 3.0. The details can be found in our blog.

Background

The cmk-migrate-http tool (introduced in Werk #17725) helped users migrate from the legacy 'Check HTTP service (deprecated)' active check to the modern 'Check HTTP web service' check. The check_http active check binary will remain in Checkmk 3.0, only the migration tooling is removed.
