Active Directory and Microsoft 365 Migration Specialists

What we do

LeadThem Consulting is a Quest Software partner since 2005, specializing in Active Directory, Entra ID (formerly Azure AD), and Microsoft 365 migrations. Our consultants use Quest On Demand Migration (ODM) and Quest Migrator Pro for Active Directory to plan and execute complex migrations for organizations across the United States. All of our resources are Quest Certified.

Most of our clients come to us with a deadline behind a merger, an acquisition, a compliance requirement, or infrastructure they have been deferring. We have seen every variation. Migrations that look routine on paper rarely are in practice, and that is exactly where our project experience since 2005 matters. See our migration services for the full list of supported workloads.

ODM and Migrator Pro for Active Directory are part of Quest Secure Migration, one of two solutions in the Quest Security Management Platform. The other, Quest Identity Security and Resilience, covers the recovery and threat-detection products LeadThem operates for clients who want continuous protection of the environments we migrate.

What does LeadThem Consulting do?

LeadThem Consulting (LTC) is a US-based IT consulting firm specializing in Active Directory consolidations, Entra ID transitions, and Microsoft 365 tenant-to-tenant migrations. The firm has been a Quest Software partner since 2005 and runs migration and managed-services engagements for enterprises across the United States.

When was LeadThem Consulting founded?

LeadThem Consulting was founded in 2005 by Scott Leadham. The firm has operated continuously as a Quest Software partner since that year.

What is LeadThem Consulting's relationship with Quest Software?

LeadThem is a long-standing Quest Software channel partner, working primarily with Quest Migrator Pro for Active Directory and the Quest On Demand Migration (ODM) family. Consultants are Quest-trained on the migration and identity-security product lines.

Where is LeadThem Consulting based?

LeadThem Consulting is headquartered in the United States and delivers engagements nationwide. The team works remotely from client sites or from secure remote workstations, with travel to client sites when an engagement requires it.

Who are LeadThem's typical clients?

Typical clients are mid-market and enterprise IT organizations running mergers, divestitures, or modernization programs that touch Active Directory, Microsoft 365, or both. Many engagements come from companies that have just acquired another business and need to consolidate two Microsoft estates onto one.

How do LeadThem engagements work?

LeadThem runs two engagement shapes. Enablement engagements run two or more weeks: LTC architects stand up the Quest tooling, validate the migration approach, run a pilot wave, then teach the customer team to finish the work on their own. Micros are shorter training-led engagements with optional consulting hours bundled in.
