Dynamics 365

Updating FieldOne organizations to Field Service

Thank you for your continued loyalty and support as a FieldOne customer as Microsoft transitioned the capabilities of the legacy FieldOne product into Dynamics 365 for Field Service. As part of this transition, Microsoft made significant investments in new features, as well as updating compliance and security functionality to the Dynamics 365 for Field Service application.

Support for legacy FieldOne ended on April 1, 2018, which includes security hotfixes. Future updates to Dynamics 365 will no longer benefit FieldOne, which could cause the latter to malfunction. We recommend you upgrade to Field Service no later than February 28, 2019, to maintain optimal business operations.

In order to gain access to the most current functionality, you need to move from the legacy FieldOne software you are using to Dynamics 365 for Field Service.We are excited about how Dynamics 365 for Field Service and the other applications within the Dynamics 365 product suite help you transform your business.


Detailed information about the transition

Customer environment:  Dynamics 365 for Customer Engagement (online) + FieldOne software  Or Dynamics 365 for Customer Engagement (on-premises) + FieldOne software

What to expect: Support for legacy FieldOne software has ended. In order to access new features, upgraded compliance and security functionality, as well as on-going updates, you will need to migrate to Dynamics 365 for Field Service.
