Introduction
Learn how to migrate a site to the latest version of Drupal using Multidev
This guide will show you how to migrate a site that meets the following criteria to the latest version of Drupal:
| Current Host | How Site Was Created | Additional Requirements |
|---|---|---|
| Pantheon | Dashboard | Multidev |
If this is not your scenario, see Drupal Migration Guides for additional upgrade paths.
This upgrade will not maintain your site’s commit history.
Requirements
To maintain best practices and to avoid difficult, time-consuming repairs to the site, this doc is written for users with access to Pantheon's Multidev feature.
Pantheon support is not available to users who avoid the Multidev steps.
Confirm that your site meets the following requirements before you continue:
The site cannot be set to use an empty upstream.
The site does not use another package and library manager like Ludwig.
