Cutover Guidance

The Power Platform cutover

The Power Platform environment cutover is required to create a new NHSmail Default environment with an updated data residency in the United Kingdom.

Please note that as part of this activity, the current NHSmail Default Environment (Europe) will no longer be the Default Environment and will eventually be decommissioned.

The default environment cutover is scheduled to take place in June 2021. Closer to the time we will confirm the cutover date. Please check this page again for any updates on the cutover schedule.

What do I need to do?

The cutover will only affect those who are currently using the NHSmail Power Platform Default Environment, and the impact is limited to the functionality detailed in the table below.

Before the cutover:

Please ensure that you take the necessary steps to save any relevant work as explained in the pre-cutover column.

After the cutover:

Where applicable, instructions on what you need to do after the cutover have also been included in the table in the post-cutover column. Please make sure that you only complete them after the cutover has taken place.

IMPORTANT: You will receive communications prior to the cutover and when the cutover is complete. Completing the post-cutover activities in advance may mean your work will not be saved.

Functionality Outcome Pre-cutover
Action to take before the cutover
Post-cutover
Action to take after the cutover
SharePoint Form App Unfortunately, due to Microsoft limitation, SharePoint lists or document libraries that have had their forms customised via Power Apps will lose all customisations. Take screenshots and notes of your customised forms and its functions as soon as possible so it can be re-customised after the cutover. You need to re-customise the SharePoint lists or document libraries forms that were customised prior to the cutover.

Visit the Customise a SharePoint list or library form using Power Apps guidance and check your screenshots and notes for reference on what you need to recreate.

Standalone Project for the Web Projects All projects created before the temporary switch off of Project for the Web prior to the cutover will no longer be accessible and will need to be recreated after the cutover. You may export your project as an Excel file, as well as take screenshots and notes of your projects and its details as soon as possible so it can be recreated after the cutover. Projects created in Project for the Web before the cutover need to be recreated.

Visit the Create a project page for instructions and refer to your Excel export, as well as screenshots and notes for details.

Apps & Flows using Common Data Service (CDS) tables from the NHSmail Default environment Apps and flows that use the CDS tables from the NHSmail Default environment (i.e. Project for the Web entities) will need to be reconnected after the cutover. Take note of your apps and flows affected and inform users about the expected downtime until a reconnection is completed after the cutover.

Please note that for apps and flows using CDS custom tables, the tables and the data should be migrated to your organisation’s dedicated environment before the cutover.

Visit Migrating Common Data Service (CDS) custom tables for instructions.

You need to reconnect your apps and flows to the NHSmail Default environment for data source.

Visit the Reconnecting to Common Data Service (CDS) tables in the NHSmail Default environment page for instructions.

Power Automate Instant Flows (cloud flows) Instant Flows hosted in the Default Environment will no longer work after the cutover. Any instant flows should be migrated to your organisation’s dedicated environment before the cutover. Visit Migrating Power Automate for instructions.
