Did you read the on-boarding document

OpenSearch Migrations

What is the link to your GitHub repo?

https://github.com/opensearch-project/opensearch-migrations

Targeted release date

04/13/2026

Where should we publish this component?

ECR

• opensearchproject/opensearch-migrations-migration-companion
• opensearchproject/opensearch-migrations-transformation-shim

We have provided README documentation here for the images in their associated markdown files.

This is a follow-up to opensearch-project/.github#330 which created the initial 4 ECR repos for opensearch-migrations. We are now adding two additional images:

1. opensearch-migrations-migration-companion — An AI-powered migration guide that helps users through their entire migration journey, from assessment through cutover. See RFC #2444 and PR #2681.

2. opensearch-migrations-transformation-shim — A multi-target HTTP proxy that provides request/response transformation and parallel dispatch to support phased migrations from Solr to OpenSearch. See PR #2676.

What type of artifact(s) will be generated for this component?

Docker images for the Migration Companion (AI advisor container) and Transformation Shim (HTTP proxy), published alongside the existing opensearch-migrations images.

Have you completed the required reviews including security reviews, UX reviews?

• Security Review: Existing security reviews cover the solution code.
• UX Review: Not needed — these are command-line/container-based tools.

Have you on-boarded automated security scanning for the GitHub repo associated with this component?

Yes

Additional context

The existing 4 ECR repos were created via opensearch-project/.github#330 and opensearch-build#4857. The build infrastructure (build.gradle publishedRepoByImageName and buildKitProjects) is being updated in the linked PRs to support publishing these two new images.
