Switch from Google Workspace to GroupOffice

You can take the following steps to migrate all your data from Google Workspace to GroupOffice.

Assessment & Prerequisites

Determine what you need to migrate. The data can be mapped like this:

Google Workspace

GroupOffice

Gmail

E-mail (You need to install the GroupOffice mailserver or another IMAP server)

Drive

Files

Calendar

Calendar

Contacts

Addressbook

Make sure you have the required modules installed. To replace the google docs editors you can install Collabora office.

Sign up or install

Decide if you want to self host GroupOffice or use our cloud service. You can sign up here.

Users

Before creating users, setup groups and module permissions.

Start by creating users manually or import them via a csv or file in GroupOffice. Here you can find how to export Google Workspace users.

Note

Also consider if you want to use an SSO solution with OpenID connect, IMAP authentication or LDAP authentication.

Gmail

When migrating mail we use imapsync <https://imapsync.lamiral.info/>.

The steps to take are:

  1. Setup mailserver

    1. When self hosting then install the GroupOffice mailserver or use any IMAP compliant server.

    2. When using our cloud service and you have signed up for a mail domain you will get access to the management where you can create mailboxes

  2. Prepare your domain. Do not switch yet but determine all DNS records (MX, SPF, DMARC and DKIM) to set after migrating mail. For our cloud service we will provide them to you.

  3. Create all the mailboxes on the GroupOffice mailserver

  4. Create a list of imapsync commands using the imapsync documentation. Also read the google specific parts.

  5. Run the sync and test. You can repeat the sync at any time to update the new mailserver.

  6. Put the migration live by setting the DNS domains.

  7. Finally, run the sync again after 24 hours because some mail might still have arrived at Google.

Calendar
