Note that Pantheon's recent changes to search-replace functionality for multisites should make this script unnecessary. If possible, use the platform functionality instead. You'll have a better time. This is intended as a backup if that method fails.

Quicksilver Script - WPMU Database Clone

Pantheon Quicksilver script designed to be run when a database is cloned from live to a lower environment.

The script will update the wp_blogs and wp_site table to match the new environment's base url.

It will also update the respective wp_options table for each subsite. Note a full search and replace is not done - this can hang on large networks (200+). Those can be run on a per-site basis via terminus.

Installation

1. Copy the code to your site repo at /private/scripts

2. Run composer install inside the script folder to install its dependencies.

3. Update your pantheon.yml file to include a snippet like below. This will enable the quicksilver hook.

   workflows:
       clone_database:
           after:
           - type: webphp
               description: Convert blog urls
               script: private/scripts/quicksilver-wpms-sr/multisite.php
   

4. Edit the $domains array in multisite.php to match your site's configuration.
