Why Migrate? (Why not migrate?)

Drupal 6->7 migration

• Works well for many sites where you can just clone the db and roll.
• Might be a problem for high-content or high-complexity sites.

Migration with Migrate

• Gives the ability to import new content throughout the dev cycle.
• Allows easy refactoring of content.
• Enables migration from non-Drupal sites.
• Has full drush integration.
• Will prepare you for Drupal 8.

Prepare yourself

After you've gone through your usual planning, prototyping, and design processes...

Build out your nodes (or entities)

Make a rough field mapping from the old site to new

Install your modules

• Migrate: https://www.drupal.org/project/migrate
• Migrate d2d: https://www.drupal.org/project/migrate_d2d

Enable your modules

• Migrate (& UI)
• Drupal-to-Drupal migration (& UI)

Let's begin

From your Migrate dashboard (admin/content/migrate) click “Import from Drupal”

Enter your old db information

This could be cloned to a dev environment, or live (if you dare).

Step through initial migration steps

But don't worry, we're not committing anything just yet.

“Save Import Settings” but don’t run yet

We still have some more work to do.

Review your settings

Get your mappings

Click on each "Task" and then "Edit" to view the mappings

Each task has dependencies, but they’re in roughly the correct order:

• Pictures
• Roles
• Taxonomies
• Users
• Files
• Nodes

Pictures

Should be straightforward.

Roles

Should also be easy.

Taxonomies

Get the right source for the term parents.

Users

Maybe some text fields you've added? Set the mappings.

Files

Probably not much to change here.

Nodes

This might get tricky...

Eventually...

When at first you don't succeed...

Rollback and try again

Feeds to the rescue

Feeds pro tip: You can load data into Google Sheets and publish as CSV, then consume with Feeds URL. No more Excel saves & uploads!
