Migrating from WordPress to Grav

Migrating from WordPress to Grav

Requirements

  • PHP v7.1 or above for the composer dependencies.
  • WP-CLI installed on the WordPress host
  • Working WordPress site from which content will be exported.
  • R/W access to wp-content/uploads on the WordPress site.
  • Composer installed on the Grav host.

Installation

  1. Download the latest release of the wp2grav_exporter plugin and upload it to your WordPress's wp-content/plugins directory.
  2. Run composer install --no-dev within the wp2grav_exporter directory to install dependencies.
  3. Enable the new plugin:
    • Using wp-cli: wp plugin activate wp2grav_exporter, or - Via the admin GUI.
  4. Run wp wp2grav-all to export all items. See other options below.
  5. Exported files are located at WP_ROOT/wp-content/uploads/wp2grav-exports/DATE
  6. For Grav v1.6 sites, https://github.com/david-szabo97/grav-plugin-admin-addon-user-manager is recommended to view and manage users. This is not required for Grav 1.7+ sites.

Notes

Running wp wp2grav-all will run each of the following export steps at once. Afterwards, follow each section below on how to import the new data to a Grav install.

Exporting Users from WordPress

WordPress users exported to Grav

WordPress users on left exported to Grav on the right.

Command

wp wp2grav-users will generate Grav user account files.

Results

  • User accounts in the export directory under EXPORT/accounts/.
    • Usernames will be padded to a minimum of 3 characters, maximum of 16.
    • If a username is truncated or padded, the username will also have the WordPress uid to avoid collisions.
    • Passwords in each account are randomly generated, and have no connection with the respective WordPress account. The plaintext password automatically converts to a hashed_password once the account authenticates for the first time.

Importing Users to Grav

Copy the EXPORT/accounts directory to your user directory (e.g. username.yaml files should be placed at user/accounts).

Exporting User Roles from WordPress

WordPress roles exported to Grav groups

WordPress users with roles on left exported to Grav groups on the right.

Command

wp wp2grav-roles will generate a Grav groups.yaml file.

Results

WordPress user roles export as Grav groups in a groups.yaml file at config/groups.yaml. Some notes about the role exporting:

  • Each WordPress role is converted to the Grav group wp_<ROLE_WITH_UNDERSCORES> (e.g. subscriber becomes wp_subscriber).
  • WordPress users with administrator roles receive the wp_administrator group.
  • The wp_administrator group receives admin.super access along with admin.login access. Accounts with these permissions are full admins on the site!
  • A new Grav group called wp_authenticated_user group receives admin.login access.
  • All accounts receive the "wp_authenticated_user" group.

Importing User Roles

Copy the EXPORT/config directory to users/config.

Exported post types

WordPress post types are converte to Grav page types, with a pre-pended "WP" in front of each type (highlighted in yellow here).
