Microsoft 365 & SharePoint Migration for Long Island and NYC Businesses

Moving your email, files and phone system to Microsoft 365 shouldn’t mean lost data, days of downtime or a confused team. TCI plans every step, does the switch after hours, and trains your staff, so on Monday morning everyone just logs in and gets to work.

What We Move

Whatever you’re using today, we’ll bring it into Microsoft 365 safely and in one piece.

Files & Shared Drives → SharePoint & OneDrive

Your old file server or shared drives, moved into SharePoint and OneDrive with folders and permissions set up so the right people see the right files, from anywhere.

Email → Microsoft 365

Mailboxes, calendars and contacts from Google Workspace, an older Exchange server or another provider, moved into Outlook with nothing left behind.

Company-to-Company Moves

Merging with or acquiring another business? We combine two Microsoft 365 environments into one, so everyone shares one email domain, one directory and one set of files.

Microsoft Teams & Phones

We set up Teams for chat, meetings and file sharing, and can move your phone system onto Teams so calls reach your people on any device.

How the Move Works

A clear, four-step process, with no surprises along the way.

1. Plan & Clean Up

We review what you have, archive what you no longer need, and map out where everything will go. Less clutter means a faster, smoother move.

2. Move in the Background

Your data is copied over while your team keeps working as usual, and we check that everything arrived intact.

3. Switch Over After Hours

The final switch happens in the evening or over a weekend, so your business keeps running during the workday.

4. Train & Support

We show your team how to find files, share documents and use Teams, then stay on for ongoing support and help you back up your Microsoft 365 data.

Common Questions

How long does a migration take?

It depends on how much data you have and how many people are moving. After your free assessment, we’ll give you a clear timeline before any work begins.

Will we lose any email or files?

Our process is built so nothing gets lost: we copy everything first, verify it, and only switch over once it checks out. Your old system stays available until you’re comfortable.

Will my team have downtime?

Very little. Most of the work happens in the background, and the final switch is done after hours, so people usually just log in to the new system the next morning.

Do we need new Microsoft 365 licenses?

We’ll review what you have now and recommend the right Microsoft 365 plan for each person, so you’re not paying for more than you need.
