Drupal Migration (External to Pantheon)

Drupal 7

Step 1: Click Migrate Existing Site

Step 2: Specify the existing URL and choose existing site CMS

Step 3: Create a tar (of the site you want to migrate). SSH to your site server and run this command.

drush ard --destination=sites/default/files/P0zG8ohjLKFBI6Y.tgz

If you have site alias you can skip the SSH part and run the command locally.

drush SITE.ENV ard --destination=sites/default/files/P0zG8ohjLKFBI6Y.tgz

Where:

P0zG8ohjLKFBI6Y.tgz - is the filename of the compressed codebase from the dashboard migration page

SITE - is the site name you specified in your Drush alias (see PROJECT.drush.aliases.php)

ENV - remote environment (dev, test, live) (see PROJECT.drush.aliases.php)

Step 4: Migrate the site:

Option 1: Via Terminus

terminus import:site gv-d7-migration-test http://yourdomain.com/sites/default/files/J0x1hKz8ULQCC7V.tgz

Where:

gv-d7-migration-test - is the site name of the destination server

http://yourdomain.com/sites/default/files/J0x1hKz8ULQCC7V.tgz - is the URL of the generated archive from step 3

Note: Be cautious with the URL it contains // before sites/default.

Here is the typical error when you forgot to remove the extra /.

[error]  Unable to download archive from "http://yourdomain.com//sites/default/files/J0x1hKz8ULQCC7V.tgz", encountered HTTP Error 404: Not Found. 

Answer the question:

Are you sure you overwrite the code, database and files for dev on gv-d7-migration-test? (yes/no) [no]:

And watch the dashboard progress….

Output when migration is done:

[notice] Imported site onto Pantheon

Option 2: Via URL. Just click the Import Archive button.

Step 5: Once migration is done you will be able to see the Visit the Site Dashboard button.

Drupal 8
