# git-refs(1) Manual Page

## NAME

git-refs - Low-level access to refs

## SYNOPSIS

    git refs migrate --ref-format=<format> [--dry-run]
    git refs verify [--strict] [--verbose]

## DESCRIPTION

This command provides low-level access to refs.

## COMMANDS

migrate

  Migrate ref store between different formats.

verify

  Verify reference database consistency.

## OPTIONS

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 following options are specific to git refs verify:

--strict

  Enable stricter error checking. This will cause warnings to be reported as errors. See git-fsck(1).

--verbose

  When verifying the reference database consistency, be chatty.

## KNOWN LIMITATIONS

The ref format migration has several known limitations in its current form:

- 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.
