Plan and execute domain consolidation and rebranding with identity, DNS and user impact insights
Domain Consolidation & Rebranding is for organisations undergoing mergers, acquisitions or corporate renaming that need to rationalise multiple domains into a unified identity and naming structure. This service helps IT teams align domain names, identity systems and communications to reduce administrative complexity and improve email, directory and authentication consistency.
We assess current domains and identity infrastructure, create a consolidation plan covering cutover sequencing, DNS and branding changes, execute the migration and domain cutover with minimal disruption, and provide post-migration support and documentation. Communications, testing and rollback plans are included to manage user impact and dependencies across Microsoft 365, Azure AD, Active Directory and DNS.
Talk through your requirements and leave with a clear next-step plan.
