Migrations, mergers, cutovers, assessments. Project-based expertise for the work that has to go right the first time. Standalone, or alongside any Athencia service.
A migration. A merger. A cutover to a new system. These aren't routine tickets. They're one-time events where the whole organization is watching, the date can't move, and getting it wrong takes everyone down at once.
Most IT shops treat a project like that as a checklist and hope for the best. That works right up until the one thing that goes wrong is the thing that couldn't.
A migration is the hardest version of high-stakes IT: replacing an organization's systems while it keeps running full speed. It's like changing all four tires on a car doing 60 down the freeway, and the driver never slows down.
We have done it before, at a scale most shops never touch. The experience behind this work runs deep: more than a million mailboxes migrated, hundreds of environments supported, post-merger and acquisition migrations up to and including the Fortune 5. We know what good looks like because we have done it, and we know exactly where these projects go wrong because we have seen it.

Project work with clear scope and a clean handoff. The ones we do most:
Microsoft 365 migrations, tenant-to-tenant consolidation after a merger, Google Workspace to Microsoft 365, VMware to Hyper-V, and Azure migrations. Minimal disruption, a clean cutover, nothing left behind.
Find the gaps before someone else does. Clear findings, plain-language recommendations, no fear-selling.
Modern architecture built for performance and security, on-premises or cloud.
Standardize how devices are procured, deployed, and managed, end to end.
Technical due diligence on the systems you depend on. Objective, no vendor bias.
Readiness assessments, Copilot deployment, governance, and hands-on workshops. Full detail on the AI Services page.
Three ways to engage, depending on the shape of the project:
For defined deliverables, quoted upfront.
Best for migrations and assessments where you want a known number.
For flexible scope, pay as you go. $150 to $200 per hour.
Best for ongoing consulting.
For reserved hours at a preferred rate.
Best for an ongoing partnership.
However we bill it, every engagement runs the same way. Discovery to understand your environment and what you're trying to do. A clear scope with a timeline and a price before we start. Execution with regular updates, no going dark. And a handoff with real documentation, so nothing that matters lives only in one person's head.
Professional Services works on its own, and it works next to any managed service. Plenty of organizations start with a project and add Athencia One or One Complete afterward, so the environment we just built stays run the way it was built. The same goes for the cloud: move to Azure with us, and we can keep running it for you through Managed Cloud. There's no requirement to bundle anything.
