Migrate

Learn how to use the Platform.sh migration path.


Pantheon provides a Platform.sh path for migrating existing sites to the platform. This process begins by clicking the Migrate Existing Site button on either the workspace Home Page or Sites tab.

The recommended way to migrate WordPress sites from another host is to use the Pantheon Migration plugin, developed by BlogVault.
