The migrations we handle

From single mailboxes to a full provider switch — we plan and carry out the move for you.

Email & mailbox migration

Gmail, Outlook/Exchange and IMAP/POP — complete mailboxes including folder structure, labels and attachments.

Cloud storage migration

Google Drive, OneDrive and other storage — files, folder structure and shares are preserved.

Google Workspace move

A complete switch to or from Google Workspace — users, groups, shared drives and permissions included.

Microsoft 365 move

Mailboxes, OneDrive, groups and mailbox settings — cleanly transferred to the new Microsoft 365 tenant.

Calendars & contacts

Events including recurring series and exceptions, shared calendars plus personal contacts and groups.

Tenant & domain migration

Entire tenants including identities, groups, aliases and permissions — coordinated and predictable.

Archive & file import

Email archives (mbox/EML) plus mailboxes from Zimbra, Exchange and other servers — and files from Nextcloud, ownCloud, Dropbox or S3. Including legacy systems and backups.

SharePoint & Teams migration

Entire SharePoint sites, document libraries and lists from one Microsoft 365 tenant to another — including permissions, metadata and versions. Optionally all sites automatically.

Upfront compatibility check & planning

Before the move we check exactly what transfers 1:1 and what does not — you get a clear plan in advance and no surprises on migration day.

FAQ

Frequently asked questions

What do you carry out the migration with?

With our own, self-developed migration software. We have full control over every step and move your data exclusively via our own servers in Germany and the EU — GDPR-compliant, with no third-party cloud services.

Between which providers do you migrate?

Between Google Workspace, Microsoft 365, Microsoft Exchange, IMAP/POP servers and other providers — in virtually any combination, including cross-platform.

Does anything get lost during the migration?

No. Every email, calendar entry and file is transferred and then checked against the source per object. You receive proof of completeness.

Does our business keep running during the migration?

Yes. The bulk of the data is transferred ahead of time in the background. The actual switch-over happens in a short, planned window with minimal downtime.

Where is my data processed?

Exclusively on our servers in Germany and the EU. Processing is carried out under the GDPR, with a data processing agreement on request.

What does a migration cost?

After a free initial analysis you receive a transparent quote — at a fixed price on request, depending on the number of mailboxes and data volume.

Do you also migrate from Microsoft 365 to Google Workspace (and vice versa)?

Yes. We migrate cross-platform in both directions — from Google Workspace to Microsoft 365 and the other way round — as well as between two tenants of the same provider.

How long does a migration take?

It depends on the data volume and the number of mailboxes. The bulk runs ahead of time in the background; the actual switch-over happens in a short, planned window. After the free initial analysis we give you a concrete time frame.

What gets migrated — and what do I need to recreate on the target?

Emails, calendars, contacts, files and groups are transferred and verified per object. A few platform-specific items — such as mailbox delegation, inbox rules or SharePoint site-level permissions on Microsoft 365 — are listed in the completion report so they can be recreated on the target.
