Microsoft 365 Migration & Management for Orange County Businesses

Microsoft 365 is where your email, files and Teams live, so moving to it — or between tenants — should be invisible to your staff. We plan and run the migration, then secure, back up and administer Microsoft 365 for you as part of Managed Care.

Migrations we run

Exchange Server to Microsoft 365

Cutover and hybrid migrations from on-premises Exchange, including complex hybrid setups — a long-time specialty of our senior engineers.

Google Workspace to Microsoft 365

Gmail, Calendar, Contacts and Drive moved to Exchange Online, OneDrive and SharePoint, with Outlook set up on every computer and phone.

Tenant-to-tenant

Acquisitions, mergers, divestitures and rebrands: mailboxes, OneDrive, Teams and SharePoint moved between Microsoft 365 tenants, including domain changes.

File servers to SharePoint and OneDrive

Shared drives reorganized into SharePoint sites and Teams with the right permissions, so the cloud doesn’t inherit years of clutter.

How a migration goes

  • 01 · Plan

    Inventory and plan

    Mailboxes, shared mailboxes, licenses, DNS, devices and the apps that send email, with a written cutover plan and date.

    Cutover plan
  • 02 · Pilot

    Move a pilot group

    A few users go first, so surprises are found on a small group instead of the whole company.

    Pilot users
  • 03 · Migrate

    Copy, then cut over

    Data is copied ahead of time; mail delivery switches outside business hours, followed by a final sync.

    Exchange Online
  • 04 · Day one

    Support on day one

    Outlook, Teams and phones set up and checked, with our help desk ready and on-site help when you need it.

    On-site support
  • 05 · Secure

    Lock it down

    MFA and conditional access, device management, SPF, DKIM and DMARC, and the old system retired cleanly.

    Intune · DMARC
  • 06 · Manage

    Day-to-day administration

    After the move, we manage users, licenses, security settings and backups as part of Managed Care.

    Managed Care

Protecting Microsoft 365 sign-ins starts with strong, unique passwords and MFA. We add Keeper Password Manager with Microsoft 365 sign-in, so staff get shared team vaults without reusing passwords.

After the move: managed for you

  • Administration: users, licenses, groups, shared mailboxes, Teams and SharePoint permissions, handled by our help desk.
  • Security: MFA and conditional access, managed devices, email security on top of Microsoft’s filtering, and alerts on risky sign-ins and suspicious inbox rules.
  • Backup: cloud backup for Microsoft 365 email and files, included in Managed Care with no storage charge.
  • Licensing reviews: your vCIO checks licenses every quarter so you aren’t paying for unused or oversized plans.
  • Training: security awareness training and simulated phishing for every user.

On-site included, no trip fees

Engineers who come to you

Areas we serve →

We re-earn your business on every ticket. No contract ever replaces doing the work well. Every user who opens a ticket gets a satisfaction survey when it closes, and every score is visible to our whole team and leadership — the averages are published live for anyone to see.

Best-of-breed, by design

Industry-leading tools, chosen and run by engineers

We’re technology agnostic: we don’t resell a single vendor’s bundle or push the platform with the best margin. Every tool we recommend is a best-of-breed industry leader — selected, tested and configured by our own engineers because it’s right for your business.

Our leadership team is highly technical. Our co-founders, Kevin Nichols and Joe Kemp, are hands-on engineers, not just managers, and they constantly re-evaluate our tools and service offering — retiring what falls behind and adding what keeps clients ahead.

Microsoft 365 FAQs

Will we lose email during the migration?

It shouldn’t happen. Mail, calendars and contacts are copied ahead of time, and mail delivery switches over at a planned time outside business hours. Staff open Outlook the next morning and their mail is there.

Is Microsoft 365 administration included in Managed Care?

Yes. Day-to-day Microsoft 365 administration — users, licenses, shared mailboxes, Teams and SharePoint permissions — is included. Microsoft licensing is billed separately, and migrations are fixed-fee projects for Managed Care clients.

Do we need to back up Microsoft 365?

Yes. Microsoft keeps the service running, but deleted and overwritten data, ransomware and departed employees’ mailboxes are your responsibility. Managed Care includes cloud backup for Microsoft 365 and Google Workspace email and files, with no storage charge.

Do you support Google Workspace too?

Yes. We support both Microsoft 365 and Google Workspace, and we move companies in either direction.

Can you help us get ready for Copilot?

Yes. Copilot can surface anything a user has access to, so we clean up sharing and permissions first. See our AI and Copilot readiness assessment.
