GitHub introduces continuous-sync Enterprise Live Migrations for GHES-to-cloud moves
GitHub Enterprise Live Migrations entered public preview as an additional migration path for repositories moving from GitHub Enterprise Server to GitHub Enterprise Cloud with data residency, using continuous synchronisation to reduce final cutover time.
Previous state
Repository migrations relying on tools and cutover patterns that may require a longer code freeze.
Current state
An optional continuous-sync service designed for high-activity repositories and short final cutovers.
Affected users
Who needs to care
Enterprise administrators planning migrations from supported GitHub Enterprise Server versions to GitHub Enterprise Cloud with data residency.
Required response
What to do
Evaluate ELM for repositories where downtime or large monorepo scale makes a traditional cutover difficult; confirm the supported GHES patch level and keep GitHub Enterprise Importer in the tool-selection decision.
Evidence boundary
What the source does not prove
The announcement establishes public-preview availability and supported GHES patch families. It does not retire GitHub Enterprise Importer, mandate ELM, guarantee zero downtime, or state a general-availability date.
