Email and data migration

Move your email and files from any platform, without losing a message.

Microsoft 365, Google Workspace, Exchange, cPanel and IMAP hosting, Zoho, Dropbox, Box, OneDrive and SharePoint. We move mail, calendars, contacts, files and shared drives while your team keeps working, switch over in a window you choose, and close only when the counts match on both sides.

Product names and logos belong to their respective owners. Guanacos Tech is an independent consultancy; we run each vendor's own migration tools as a service.

The routes we run

From where you are to where you are going.

Most moves we run end in Google Workspace or Microsoft 365. Each route has its own tools, limits and losses, so each has its own page.

What we move

Not just the inbox. Everything your team works from.

A migration that moves mail and forgets the shared drive is half a migration. This is what goes where on the two most common destinations.

WhatInto Google WorkspaceInto Microsoft 365
MailFull history; Outlook folders become Gmail labelsFull history; Gmail labels become folders
CalendarsEvents including recurring ones; Teams meeting links kept as linksEvents and attendees; room bookings and shared calendars rebuilt by hand
Contacts and tasksContacts, and Microsoft To Do tasks from Exchange OnlineContacts (up to three addresses each)
Shared mailboxes and groupsShared mailboxes become Collaborative Inboxes; distribution lists become Google GroupsGoogle Groups become distribution lists or Microsoft 365 groups
Personal filesOneDrive and Dropbox to each user's My Drive, in their existing formatMy Drive to OneDrive; Docs, Sheets and Slides converted to Word, Excel and PowerPoint
Team filesSharePoint sites, Dropbox team folders and Box to shared drivesShared drives to SharePoint sites or Teams
Sharing and permissionsMapped by user and group from an identity mapShared drive permissions mapped; file-level sharing on request

Based on Google's and Microsoft's own migration documentation, checked October 2026. Limits change; we confirm them for your tenant during discovery.

What usually does not survive

The losses, named before we start.

Every vendor tool leaves something behind. Knowing it up front is the difference between a plan and a surprise on Monday morning.

  • Previous file versionsGoogle's tools import the current version of OneDrive, SharePoint and Dropbox files. If a version history matters, we export it first.
  • Outlook rules and calendar permissionsThey need Google's advanced import method, or we rebuild the ones that still matter as Gmail filters and sharing.
  • Dropbox Paper and SharePoint listsNot migrated by the vendor tools. We export them to documents or sheets your team can keep.
  • Very large messages and long folder pathsMessages over the destination's size limit and very deep folder paths are listed per user, so nobody wonders where they went.
  • Files owned by outsidersItems shared with you by people outside the company stay with their owner. We list them so they can be re-shared.
  • Rules arriving switched offMicrosoft's Gmail import brings filters across as Outlook rules that start disabled. We switch on the ones you still use.

Every route, the same order.

The tool changes with the route. The sequence does not, and it is what keeps mail flowing.

  1. Inventory

    Every user, alias, shared mailbox, group, calendar resource, file library and integration that sends mail, with sizes, and the losses list for your route.

  2. Identity first

    Accounts, aliases and groups created and licensed on the destination before any data moves. The vendor tools need them to exist.

  3. Authentication before the switch

    The destination's SPF and DKIM published while the old system is still authorized, so receivers trust the new platform from its first message.

  4. Pilot, then seed

    A few users first, then the bulk of the history copied in the background while everyone keeps working on the old system.

  5. Cutover in your window

    MX changed at the hour you choose, both sides receiving during the switch, and a final sync of whatever arrived in the last hours.

  6. Reconcile and hand off

    Message and file counts compared per user on both sides, the old system kept read-only for a period you set, and a one-page runbook for your next admin.

Timeline and pricing

How long it takes, and how the price is set.

Typical calendar time from kickoff to reconciled hand-off for mail, calendars and contacts. Large file libraries add seeding time in the background, not downtime.

5users

Two to three working days

A founder, a few staff and a shared inbox. Cutover on an evening, everyone signed in the next morning.

25users

About one week

Groups, shared mailboxes and a file library come into play. One seeding pass, one evening or weekend cutover.

100users

Two to three weeks

Seeded in waves by department with a pilot group first. The MX change still happens once, in one window.

  • One fixed price per migration. Set after the discovery call from the number of users, the sources and the file volume. It changes only if the scope does.
  • Licences are yours. You buy Google Workspace or Microsoft 365 directly on the plan that fits. We advise on the tier; we do not resell it.
  • Included. Planning, data migration, DNS and email authentication, the cutover window, reconciliation, a sign-in session for your team and thirty days of questions afterwards.

How we scope, quote and invoice is on how we work.

Before you decide

Straight answers.

Which platforms do you migrate?

Microsoft 365, Exchange Online and on-premises, Google Workspace, personal Gmail, cPanel, GoDaddy, Hostinger and Zoho mail, and OneDrive, SharePoint, Google Drive, Dropbox and Box files.

Will we lose email?

No. The old system keeps receiving until MX changes, both sides receive during the switch, a final sync catches the last hours, and counts are compared before we close.

Do people need to do anything?

Sign in once, set up 2-step verification, and attend a short session. Their mail, folders, calendar and files are already there.

Is anything deleted on the old system?

Not by us. Google's import tools and Microsoft's Migration Manager copy the data. The old system stays read-only for a period you choose, then we help you close it.

What about our email reputation?

SPF, DKIM and DMARC go live on the destination as part of the move. Our email deliverability service continues from there if you want it.

Are you a reseller?

No. Guanacos Tech is an independent consultancy with Google-certified engineers. You buy the licences, we do the work, and we answer to you.
