Google Workspace to Microsoft 365 Migration: What Charleston Businesses Need to Know

A lot of Charleston businesses start out on Google Workspace because it’s cheap, familiar, and easy to set up with a handful of employees. Then the business grows, starts working with clients or vendors who standardize on Word and Excel, or needs the kind of security and document control that Google Drive folders were never really built for — and suddenly Workspace feels like something the business has outgrown rather than something that’s working for it.

Moving to Microsoft 365 is the right call for a lot of growing businesses, but it’s a real migration, not a settings toggle. Here’s what actually moves, where these projects tend to go wrong, and how we handle it so a business doesn’t lose a day of email or a folder of client files in the process.

Why Charleston Businesses Move From Google Workspace to Microsoft 365

We hear a few reasons consistently:

• Client and vendor expectations. A lot of industries — legal, financial services, construction, real estate — run on Word and Excel by default, and constant format conversion between Google Docs and Office files creates friction that adds up.
• Real document management, not folder sprawl. SharePoint gives a business actual structure, permissions, and version history instead of a Google Drive that’s grown organically for years with no consistent organization.
• Stronger built-in security. Microsoft’s security and compliance tooling (conditional access, data loss prevention, sensitivity labels) is deeper than what most small businesses ever configure in Workspace.
• Teams becomes the hub. Once a business is using Teams for calls and meetings anyway, having chat, files, and calendar in the same ecosystem removes a lot of app-switching.

We saw this firsthand with New Leaf Landscaping, one of our managed IT clients. They were running on Google Workspace with no real backup strategy and no cybersecurity in place — not even MFA on their email. We migrated them to Microsoft 365 Business Standard, built out a proper SharePoint site for their team data, and layered in real security on top. It’s a good example of what this move actually looks like in practice.

What Actually Has to Move (It’s Not Just Email)

A Google Workspace to Microsoft 365 migration touches more than most business owners expect:

• Mail: every mailbox, folder structure, and message history moving from Gmail to Exchange Online/Outlook
• Calendars and contacts: including shared and resource calendars, which don’t always map over cleanly
• Files: Google Drive and Shared Drives moving to OneDrive and SharePoint, with Google Docs, Sheets, and Slides converted to Word, Excel, and PowerPoint format
• Groups and distribution lists: rebuilt in Microsoft 365 so nothing silently stops forwarding mail
• Mobile devices: every phone and tablet needs its mail and calendar profile reconfigured
• Third-party app connections: anything using “Sign in with Google” — accounting software, CRMs, scheduling tools — needs to be re-authenticated against the new environment

Where These Migrations Go Wrong

Most of the migration horror stories we hear about come down to a handful of avoidable mistakes:

• DNS and MX record cutover timing. Switch too early or too late and mail gets lost or delayed during the transition window.
• Shared Drive permissions that don’t map 1:1. Google’s sharing model and SharePoint’s permission structure aren’t the same, and a lazy migration just dumps files into one folder with no access control.
• Calendar invites breaking. Recurring meetings and shared calendars are notorious for not surviving a sloppy migration intact.
• No end-user training. The data moves fine, but nobody told the team how to find their files in OneDrive instead of Drive, so productivity tanks for weeks anyway.

How We Handle a Migration

We treat this as a project with a plan, not a weekend cutover:

1. Discovery: we audit what’s actually in use — mailboxes, shared drives, groups, connected apps — so nothing gets missed or migrated that didn’t need to be.
2. Staged migration: mail and files get migrated ahead of the cutover wherever possible, so the actual switchover window is as short as possible.
3. Verification: we check mail flow, file counts, and permissions after the move, not just that the migration tool reported success.
4. Team onboarding: a short walkthrough so your team knows where things live in Microsoft 365 from day one.
5. Security hardening: once you’re in Microsoft 365, we turn on MFA, conditional access, and the cybersecurity monitoring most businesses never had configured in Workspace to begin with.

FAQs

How long does a Google Workspace to Microsoft 365 migration take?

It depends on how much data and how many mailboxes are involved, but most small-to-midsize business migrations are planned around a single weekend cutover after data has already been pre-staged, so day-to-day disruption is minimal.

Will we lose any data during the migration?

Not if it’s planned correctly. We verify mail, files, and permissions after the migration completes rather than assuming the migration tool did everything correctly on its own.

Do we need to migrate everything at once?

No. Mailboxes and files can often be staged ahead of the actual cutover date, which is part of how we keep the real disruption window short.

What happens to our shared Google Drive folders?

They get rebuilt as SharePoint sites or shared document libraries in Microsoft 365, with permissions mapped as closely as possible to how your team already shares files — and cleaned up where the old structure had grown messy.

Can our team keep working during the migration?

Yes. Most of the heavy lifting happens in the background before the cutover, so the actual switch is designed to happen outside business hours whenever possible.
