Beginning February 2019, Dynamics 365 for Talent customers based in the United Kingdom will be able to provision Talent in the United Kingdom region and all Talent data will be maintained solely within United Kingdom.
New environments can be created and deployed using LCS.
Also very important: Data migration of existing projects from other regions to the United Kingdom region is not supported. Only new projects can be provisioned to the United Kingdom region.
