@drodriguez-305 This builds locally fine, but is timing out on GitHub. We can try a re-run in the morning.

Hi Folks - there are typos in the file name that might be causing the weirdness we are seeing with the build. Since it looks like this is present on the main branch, it's indexed with the typo. We'll need to have a redirect with the typo'd URL and correct the file names before merging this PR. Since there is a mismatch in the filename/id, please look at the URLs in this branch and prod to confirm what needs to be in the redirects.

docs/self-managed/setup/guides/configure-elastcisearch-opensearch-prefix-indices.md needs to be docs/self-managed/setup/guides/configure-elasticsearch-opensearch-prefix-indices.md

So I ran a little test with #5687 -- I changed each of the files and their text only, but GitHub is saying we actually moved the file in next and placed it in the 8.5 docs, and then created a brand new dow for next -- we didn't do this.

I think this is contributing to the wonkiness here, I'm unsure why GitHub is registering that the next file was moved into 8.5, when I only edited the text in each and every file.
