Migrating Contacts

The obvious way to migrate contacts is using the web UI and 'Export contacts as Google csv".

While this does, of course, work, it will not copy the contact pictures over. Plus, there is a much easier way, provided you have an Android phone with both accounts configured:

• Open the Contacs app, make sure only the contacts from Google Apps are visible (select in the left hamburger menu).
• Select one contact with a long press, then use the three dots menu in the upper right corner to select all
• In the same menu, select "move contacts to another account"

Done.
