How to request your data move


Applies to: Office 365

Topic Last Modified: 2018-03-20

The information on this page only applies to customers who had existing Office 365 tenants before the new datacenters in their geo launched.

Existing Office 365 customers will need to submit a request before the deadline for their country in order to have the customer data of their participating Office 365 services moved to their new geo.

We are unable to accept requests to be moved after the deadline in each geo.

This option is only available on the Office 365 admin center Preview. For instructions on how to access this, see Office 365 for business – Admin Help. All requests for moves need to be done through the Office 365 admin center. Support will not be able to make this selection for you or override your selection.

Eligible customers will see a page in their Office 365 Admin Center, which will allow them to request to have their core customer data moved to their new datacenter geo.

To access the page in the Office 365 admin center, in the navigation pane on the left, expand Settings, and then click Organization Profile.

Settings menu with Organzational Profile highlighted

On the Organization Profile page, scroll down to the Data Residency Option section.

Data residency card
You may not see this section if one of the following apply:
  • Your tenant is not eligible for the move program.

  • All of your data is already located in the new geo (see Data Location section of the page).

You are about to make an important choice for your organization. After confirming the option below, you cannot undo it. Support is unable to reverse this decision as well.

If your organization has data residency requirements, and you need to request a move, click Edit on the top right of the section. A new section will appear on the right side of your screen explaining the details of the move program. Select the toggle button next to the text that says Yes, my organization has data residency requirements. Then, click Save.

Datacenter opt-in action screen

You should see the text on the Data Residency Option section change to indicate Your organization has requested to move its core customer data. You'll also have a confirmation message in your message center. This confirms that you have successfully requested a move.

After requesting a move, we will plan to move you as quickly as our operational constraints allow for. Due to the unpredictable nature of many of the constraints, we cannot share a specific date or timeframe for the moves. You will see a notification after the move has completed.

Moves may take up to 24 months from the request deadline for your country to complete.

After requesting a move, it is not possible to change your selection as we begin to process the moves once you have made the request.

Perform the following steps as appropriate.

We recommend using DNS filtering for firewalls instead of IP addresses. There are no new DNS entries required.

If you use an IP-based firewall for Internet connectivity, you must add allow rules for the new IP addresses for the destination datacenter geo. IP addresses for new datacenter geos in addition to new servers are continuously added to Office 365 URLs and IP Address Ranges.

Consult your firewall documentation for information about how to add allow rules (also known as whitelisting.)

After adding IP addresses, you may want to test connectivity to the new datacenter geo. To do this, we recommend creating a new free 30-day trial tenant as soon as the new datacenter geo is available.

If you'd like to test connectivity prior to the move, you can set up a new free 30-day trial tenant after the new datacenter geo is available, and use it to experience Office 365 hosted in the new datacenter geo.

The trial tenant can’t be combined with your existing tenant:

  • Users must use a separate trial account for their testing.

  • There is no way to move data between tenants.

If users have a mobile device with the Exchange Server set to m.outlook.com or podxxxxx.outlook.com, recommend that they switch to outlook.office365.com, following the instructions in  Set up a mobile device to synchronize with your account.
