Enterprise Live Migrations is now in public preview

Introduces Enterprise Live Migrations (ELM) for Azure DevOps repositories to GitHub Enterprise Cloud with data residency. ELM supports continuous synchronization of repository data, commit history, branches, tags, branch policies (converted to GitHub rulesets), and pull request metadata, comments, and user history. It allows for coordinated multi-repository migrations with a final cutover typically under 30 minutes. ELM is available via Azure DevOps CLI and web UI. It does not migrate work items, pipeline definitions, releases, wikis, test artifacts, or Azure Artifacts. It also details how Azure Pipelines can be rewired to GitHub repositories and how Azure Boards can continue to be used.
