git-refs - Low-level access to refs
git refs migrate --ref-format=<format> [--dry-run]
This command provides low-level access to refs.
migrate
Migrate ref store between different formats.
The following options are specific to git refs migrate:
--ref-format=<format>
The ref format to migrate the ref store to. Can be one
of:
•files for loose files with packed-refs.
This is the default.
•reftable for the reftable format. This
format is experimental and its internals are subject to change.
--dry-run
Perform the migration, but do not modify the repository.
The migrated refs will be written into a separate directory that can be
inspected separately. The name of the directory will be reported on stdout.
This can be used to double check that the migration works as expected before
performing the actual migration.
The ref format migration has several known limitations in its
current form:
•It is not possible to migrate repositories that
have reflogs.
•It is not possible to migrate repositories that
have worktrees.
•There is no way to block concurrent writes to the
repository during an ongoing migration. Concurrent writes can lead to an
inconsistent migrated state. Users are expected to block writes on a higher
level. If your repository is registered for scheduled maintenance, it is
recommended to unregister it first with git-maintenance(1).
These limitations may eventually be lifted.
