A controlled cutover
Sequence account preparation, data movement, DNS changes, validation, and communication around a defined change window.
Plan the cutover before changing the records
Email and workspace migration support with a verified rollback path.
ATS supports Microsoft 365, Google Workspace, domain email, mailbox cutovers, DNS changes, user setup, testing, documentation, and post-migration troubleshooting.
What the work needs to accomplish
A migration succeeds when people can keep working.
Moving business email affects identity, access, DNS, devices, shared resources, applications, security, and day-to-day communication. The migration plan must account for the current provider, users, aliases, groups, shared mailboxes, historical data, domain records, applications, and support needs.
ATS uses an inventory, documented target configuration, pre-change backup where supported, staged preparation, explicit cutover steps, and verification. Provider limitations and responsibilities are identified before the change rather than discovered during a live mail outage.
Users who can sign in and work
Plan identities, licenses, passwords, multi-factor setup, devices, shared resources, and first-day support.
Documented DNS and ownership
Record the provider, domain controls, mail records, aliases, administrators, verification checks, and rollback conditions.
Capabilities and deliverables
What ATS can help plan, build, connect, or improve.
Scope follows the verified business need. A project can use one capability or combine several where the customer journey and technical system genuinely connect.
Microsoft 365 migration support
Tenant and user preparation, licenses, mailboxes, aliases, shared resources, domain setup, DNS, and validation.
Google Workspace migration support
Workspace account preparation, users, groups, aliases, domain verification, mail routing, DNS, and checks.
Domain email cutovers
Current-state inventory, DNS TTL planning, MX and supporting mail records, transition sequence, and rollback documentation.
Mailbox and user setup
Supported data-migration paths, account provisioning, sign-in checks, multi-factor planning, and device guidance.
Application and form email review
Website forms, SMTP services, scanners, notifications, and other systems that may rely on the old mail configuration.
Post-migration support
Delivery checks, aliases, permissions, client configuration, DNS verification, troubleshooting, and documentation updates.
Typical project outputs
Useful artifacts, not mystery work.
Exact deliverables depend on scope, access, current systems, platform limitations, and the agreed release plan.
- Provider and account inventory
- User/mailbox/resource map
- DNS and application dependency review
- Migration and cutover plan
- Backup/rollback procedure
- Verification checklist
- Admin and user handoff notes
A practical delivery path
Understand the system. Make the change. Verify the result.
Material production work is backed up first, released with a documented rollback path, and tested on the live experience immediately.
- 01
Inventory
Record providers, users, mailboxes, aliases, groups, domains, DNS, applications, devices, and access.
- 02
Prepare
Configure the destination, verify prerequisites, lower DNS risk where appropriate, and document rollback.
- 03
Cut over
Execute the approved sequence, move supported data, change required records, and communicate status.
- 04
Verify
Test inbound/outbound mail, users, aliases, shared resources, applications, DNS, security, and support needs.
Frequently asked
Questions to clarify before the work begins.
Can ATS migrate between Google Workspace and Microsoft 365?
ATS can support migrations involving these platforms when the source, destination, licenses, data scope, access, and supported migration path are defined.
Will email stop during the migration?
The plan aims to minimize disruption, but DNS propagation, provider behavior, account changes, and data volume can affect timing. Cutover and rollback conditions are documented in advance.
What else can break when mail records change?
Website forms, SMTP services, scanners, applications, aliases, forwarding, calendars, devices, and authentication settings may depend on the old environment and should be inventoried.
Can ATS help users after the cutover?
Yes. Post-migration support can cover sign-in, client configuration, aliases, shared resources, delivery checks, permissions, and documented escalation.
