Description

We need tests that check that mixed-version X-Pack clusters are working correctly, in particular now that they're becoming the default distribution. Having such tests can uncover X-Pack BWC issues such as found in #30859.

Research direction
Review the existing test infrastructure in Elasticsearch, focusing on the 'test' directory and cluster test harnesses. Examine the referenced issue #30859 for details on X Pack BWC issues. Consider creating integration tests that simulate mixed version clusters using tools like 'vagrant' or Docker containers. Check comments in this issue for any prior attempts or guidance.
