# NAME
|
|
|
|
git-annex migrate - switch data to different backend
|
|
|
|
# SYNOPSIS
|
|
|
|
git annex migrate `[path ...]`
|
|
|
|
# DESCRIPTION
|
|
|
|
Changes the specified annexed files to use the default key-value backend
|
|
(or the one specified with `--backend`). Only files whose content
|
|
is currently available are migrated.
|
|
|
|
Note that the content is also still available using the old key after
|
|
migration. Use `git annex unused` to find and remove the old key.
|
|
|
|
Normally, nothing will be done to files already using the new backend.
|
|
However, if a backend changes the information it uses to construct a key,
|
|
this can also be used to migrate files to use the new key format.
|
|
|
|
When you have multiple repositories that each contain a copy of a file,
|
|
it's best to run migrate in all of them.
|
|
|
|
# OPTIONS
|
|
|
|
* `--backend`
|
|
|
|
Specify the new key-value backend to use for migrated data.
|
|
|
|
* `--force`
|
|
|
|
Force migration of keys that are already using the new backend.
|
|
|
|
* file matching options
|
|
|
|
The [[git-annex-matching-options]](1)
|
|
can be used to specify files to migrate.
|
|
|
|
* Also the [[git-annex-common-options]](1) can be used.
|
|
|
|
* `--remove-size`
|
|
|
|
Keys often include the size of their content, which is generally a useful
|
|
thing. In fact, this command defaults to adding missing size information
|
|
to keys. With this option, the size information is removed instead.
|
|
|
|
One use of this option is to convert URL keys that were added
|
|
by `git-annex addurl --fast` to ones that would have been added if
|
|
that command was run with the `--relaxed` option. Eg:
|
|
|
|
git-annex migrate --remove-size --backend=URL somefile
|
|
|
|
* `--json`
|
|
|
|
Enable JSON output. This is intended to be parsed by programs that use
|
|
git-annex. Each line of output is a JSON object.
|
|
|
|
* `--json-error-messages`
|
|
|
|
Messages that would normally be output to standard error are included in
|
|
the JSON instead.
