Describe the solution you'd like

Essentially, I think we just need to delete the distribution/tools/upgrade-cli directory. It may be referenced in some Gradle files that need to be cleaned up too.

Also distribution/src/bin/opensearch-upgrade[.bat], both of which can be deleted as well.

% git grep 'upgrade-cli'
.github/dependabot.yml:  - directory: /distribution/tools/upgrade-cli/
distribution/build.gradle:    libsUpgradeCli project(path: ':distribution:tools:upgrade-cli')
distribution/build.gradle:        into('tools/upgrade-cli') {
distribution/src/bin/opensearch-upgrade:  OPENSEARCH_ADDITIONAL_CLASSPATH_DIRECTORIES=lib/tools/upgrade-cli \
Binary file distribution/src/bin/opensearch-upgrade.bat matches
distribution/tools/upgrade-cli/build.gradle:  archivesName = 'opensearch-upgrade-cli'
settings.gradle:  'distribution:tools:upgrade-cli',

@msfroh Thanks for creating this - looks save to remove. Didn't see any dangling references elsewhere in the project that need to be updated. I only see refs to build manifests where this was included.

Thanks @andrross I stand corrected, it looks like there are references in the docs website https://github.com/opensearch-project/documentation-website/blob/main/_upgrade-to/upgrade-to.md#upgrade-tool

• Markdown - https://github.com/opensearch-project/documentation-website/blob/main/_upgrade-to/upgrade-to.md#upgrade-tool

@peternied I don't believe that "update-to" section is still accessible. It seems to redirect to the migration assistant now:
