Over the last several years, we’ve encouraged customers to move their repositories from Azure Repos to GitHub to take advantage of the latest AI-powered and agentic development experiences.
For many enterprise teams, however, migrating at scale comes with real constraints. Traditional approaches can require extended downtime – sometimes days – which isn’t acceptable for teams running critical workloads.
To address this, we’re introducing Enterprise Live Migrations (ELM), in limited public preview.
Migrations begin without locking the Azure DevOps repository, with changes continuously synchronized to GitHub while developers keep working. When ready, teams can schedule a cutover to complete the transition – with only a brief downtime window, typically under 30 minutes. This means no extended freeze periods, no multi-day outages – just a controlled, predictable transition that fits into your operations. Teams can migrate at their own pace, without coordinating complex, high-risk “all-at-once” migrations.
🪧 Sign up for the Preview
ELM currently supports migrations to GitHub Enterprise Cloud with data residency. A script-based migration experience is available today, with a UI-based experience coming soon to provide a more streamlined end-to-end workflow. We expect to remain in limited public preview over the next couple of months as we continue refining the experience, adding new features, and incorporating customer feedback. Your input is vital to making this experience successful.
If you are interested in participating in the preview, you can sign up today. We will follow up with all the information you need to get started.
🤖 How ELM works
ELM follows a simple, staged workflow:
- Start and validate — ensure the repository is migration-ready
- Continuous sync — keep GitHub up to date while development continues
- Cutover — perform a final sync and transition GitHub to the system of record
During most of the process, Azure DevOps remains fully writable, so teams can keep working without interruption.

💬 Conclusion and key takeaways
Enterprise Live Migrations provides a practical path for organizations moving to GitHub Enterprise Cloud with data residency:
- Minimize disruption with continuous synchronization and a short cutover window
- Reduce risk by migrating without pausing active development
- Adopt flexibly with support for hybrid Azure DevOps and GitHub workflows
Hello
Is there a plan to support this on GitHub Enterprise Cloud?
We are starting with GitHub Enterprise Cloud with data residency and plan to expand to support additional migration paths over time as the experience matures.
Didn’t you know? Microsoft is run by Microsoft haters now. Every great tech they invented they are now on a quest to destroy.
I had a Microsoft rep berate me once for targeting my cloud app to Windows Server and not Linux. Argued with me. I kid you not.
The inmates are running the asylum.
You’re “encouraging” us to switch from a superior, more secure product – a Microsoft product that dates back to when Microsoft was actually the gold standard – to an inferior, less secure one, that Microsoft didn’t create but only bought and made worse. The way Microsoft now always does.
I will never move us to GitHub. Or VS Code. Or the new Outlook for that matter.
If you try to force us you can kiss us goodbye entirely.
Announced half a year too late – we migrated hundreds of repos with our own tooling build around git-tfs. 🥹
