What is Google Workspace to Google Workspace Migration?

Google Workspace to Google Workspace migration (also called Google tenant-to-tenant or G Suite to G Suite migration) is the process of moving users, mailboxes, files and collaboration data from one Google Workspace tenant to another. It is commonly required during mergers and acquisitions, divestitures, domain consolidation or rebranding projects.

Cloudiway migrates Gmail, Google Drive, Shared Drives, Google Calendar, contacts, Google Groups and Google Chat from a single console. Because both ends are Google, native Docs, Sheets and Slides are migrated as native files, labels stay labels, and sharing permissions are recreated for the mapped target users.

Use Cases

Google Workspace Migration Scenarios

Common business situations that call for a tenant-to-tenant migration

Mergers & Acquisitions

Bring an acquired company running Google Workspace into your own domain without losing mail, files or calendars.

Divestitures

Carve out a business unit into its own Google Workspace tenant with only the users and data that belong to it.

Domain Consolidation

Merge several Google Workspace domains into a single tenant for simpler administration and licensing.

Rebranding

G Suite to G Suite Migration

Google rebranded G Suite to Google Workspace in 2020. Tenants created under G Suite Basic, Business or Enterprise editions migrate exactly the same way as Google Workspace tenants: Cloudiway connects to both domains through the Google APIs, so the licensing generation of either tenant makes no difference to the migration.

FAQ

Google Workspace to Google Workspace Migration FAQ

Common questions about migrating between Google Workspace tenants

What is a Google Workspace to Google Workspace migration?

It is the process of moving users and their data from one Google Workspace tenant (domain) to another. Cloudiway migrates Gmail, Google Drive, Shared Drives, calendars, contacts, Google Groups and Google Chat between the two tenants. This is typically needed after a merger, an acquisition, a divestiture, a domain consolidation or a rebranding.

Which data is migrated between the two Google Workspace tenants?

Gmail messages with labels, attachments, read status and stars; My Drive files and folders with sharing permissions; Shared Drives with member roles; Google Calendar events, recurring meetings and attendees; personal contacts; Google Groups with members and conversations; and Google Chat spaces with messages and files.

Are Google Docs, Sheets and Slides converted during the migration?

No. Because both source and target are Google Workspace, native Google files are migrated as native Google files. Formatting, comments and revision history behaviour follow Google API capabilities, and no Office conversion takes place.

Do Gmail labels survive the migration?

Yes. Gmail to Gmail migration keeps labels as labels, including nested labels, and preserves read/unread status, starred messages and attachments.

How are Drive sharing permissions handled?

Cloudiway maps every source user to a target user, then recreates file and folder permissions in the target tenant. Ownership is transferred to the mapped target account, and Shared Drive roles (manager, content manager, contributor, commenter, viewer) are reapplied.

Can users keep working during the migration?

Yes. Cloudiway runs an initial full pass, then delta passes that pick up new emails, calendar changes and Drive changes. Users stay in the source tenant until cutover, which usually takes place outside business hours with no downtime.

How long does a Google Workspace tenant-to-tenant migration take?

It depends on data volume, the number of users and Google API quotas. Cloudiway migrates users in parallel; a typical mailbox migrates in a few hours and Drive throughput is governed by Google API limits. Projects with thousands of users are usually delivered in weeks, planned in waves.

What happens to the primary domain and email addresses?

You can either move the domain to the target tenant at cutover, or keep both domains and add the source domain as an alias in the target tenant. Cloudiway supports both approaches and can migrate to renamed accounts using a user mapping file.

Is the migration secure?

Yes. Cloudiway authenticates with OAuth 2.0 service accounts using domain-wide delegation, encrypts all data in transit, and does not keep a persistent copy of your content. Cloudiway is ISO 27001 certified and GDPR compliant.

How much does a Google Workspace to Google Workspace migration cost?

Pricing is per migrated user, based on the workloads you select (mail, Drive, Shared Drives, Groups, Chat). Volume discounts apply. Use the instant quote form or contact sales for a scoped quote.

Do you provide planning and support for the migration?

Yes. Cloudiway offers migration assessment, planning, pilot execution and 24x5 support during production migrations, plus step-by-step guides for Gmail, Google Drive and Google Groups migrations.
