[[migrate-tool]]
==== Migrating File-based Users and Roles to the Native Realm
From 5.0 onward, you should use the `native` realm to manage roles and local
users. To migrate existing file-based users and roles to the native realm, use
the `migrate` tool that's included with the X-Pack plugin.
NOTE: When migrating from Shield 2.x, the `migrate` tool should be run prior
to upgrading to ensure all roles can be migrated as some may be in a deprecated
format that {xpack} cannot read. The `migrate` tool is available in Shield
2.4.0 and higher.
The `migrate` tool loads the existing file-based users and roles and calls the
user and roles APIs to add them to the native realm. You can migrate all users
and roles, or specify the ones you want to migrate. Users and roles that
already exist in the `native` realm are not replaced or overridden. If
the names you specify with the `--users` and `--roles` options don't
exist in the `file` realm, they are skipped.
Run the migrate tool after you install the X-Pack plugin. For example:
[source, sh]
----------------------------------------------------------------------
$ bin/x-pack/migrate native -U http://localhost:9200 -u elastic -p changeme
-n lee,foo -r role1,role2,role3,role4,foo
starting migration of users and roles...
importing users from [/home/es/config/shield/users]...
found existing users: [test_user, joe3, joe2]
migrating user [lee]
{"user":{"created":true}}
no user [foo] found, skipping
importing roles from [/home/es/config/shield/roles.yml]...
found existing roles: [marvel_user, role_query_fields, admin_role, role3, admin,
remote_marvel_agent, power_user, role_new_format_name_array, role_run_as,
logstash, role_fields, role_run_as1, role_new_format, kibana4_server, user,
transport_client, role1.ab, role_query]
migrating role [role1]
{"role":{"created":true}}
migrating role [role2]
{"role":{"created":true}}
role [role3] already exists, skipping
no role [foo] found, skipping
users and roles imported.

[[migrate-tool-options]]
The `native` subcommand supports the following options:
`-U`, `--url`::
Endpoint URL of the Elasticsearch cluster to which you want to migrate the
file-based users and roles. Required.
`-u`, `--username`::
Username to use for authentication.
`-p`, `--password`::
Password to use for authentication.
`-n`, `--users`::
Comma-separated list of the users you want to migrate. If not specified, all
users are migrated.
`-r`, `--roles`::
Comma-separated list of the roles you want to migrate. If not specified, all
roles are migrated.
Additionally, the `-E` flag can be used to specify additional settings. For example
to specify a different configuration directory, the command would look like:
[source, sh]
----------------------------------------------------------------------
$ bin/x-pack/migrate native -U http://localhost:9200 -u elastic -p changeme -Epath.conf=/etc/elasticsearch
----------------------------------------------------------------------
