Turning a Three-Way Merger Into One Governed Environment
After three companies combined, the new business was operating across overlapping domains, user directories, and software with no single inventory of what it owned. The visible brand change was only one part of the transition. The DORIAN Group assessed 26 core applications, sequenced identity and access work, and drove 74 of 87 integration workstreams to completion while employees continued working through the change.

The Outcome
The Challenge
Three companies had become one, but their technology environments had not. Multiple domains, several user directories, overlapping business systems, and an undocumented software estate made it difficult to see what should be consolidated, migrated, retired, or left in place.
The combined workforce still needed access to Salesforce, NetSuite, Slack, Zoom, Google Workspace, Microsoft 365, Atlassian, OneLogin, AWS, Marketo, Tableau, and other daily systems. Identities, email addresses, and access controls had to change without locking people out. The program needed a sequence that protected business continuity while making the new organization feel like one company.
Our Approach
Turn The Unknown Into A Managed Program
The DORIAN Group opened with an inventory and merger strategy covering all 26 core applications. Each system received a decision, an owner, dependencies, and a place in the sequence. That gave the integration a working control surface instead of a collection of disconnected migration requests.
Put Identity At The Center
Identity and access came next because the rest of the environment depended on it. The work covered SSO evaluation, OneLogin enablement, user provisioning, domain changes, and access controls, followed by the collaboration tools employees notice immediately when they fail: Slack, Google Groups, Microsoft 365, Zoom, and phone service.
Coordinate Business Systems And Brand
Salesforce and NetSuite consolidation ran alongside an Atlassian migration and the rebranding work across employee-facing systems. Every workstream carried an owner, status, and dependency chain. Blocked or deferred work was escalated openly so remaining decisions stayed visible rather than becoming hidden integration risk.
Inventory
Catalogued 26 core applications and set a consolidate, migrate, retire, or defer decision for each.
Identity
Planned and enabled SSO, provisioning, domain changes, and access controls for the combined workforce.
Migrate
Moved users, email addresses, and data across collaboration, finance, CRM, and operational platforms.
The Outcome
74 of 87 workstreams are complete. Employee-facing systems carry the new brand, user identities and email addresses have moved across Microsoft 365, Salesforce, Tableau, Adobe, Asana, Dropbox, and the rest of the estate, and identity connections are configured for the systems that needed them.
More importantly, the post-merger environment is now a governed program. The technology landscape that began as an unknown has visible ownership, dependencies, and sequence. What remains is in the open, with a path to completion rather than waiting to be discovered during the next operational change.
