Rollout & Migrations

Windows 11 Migration.

Structured migration from Windows 10 (or earlier) to Windows 11, covering readiness assessment, image build, pilot, and enterprise-wide deployment.

Overview

What is Windows 11 Migration?

Windows 11 migration services encompass compatibility assessment, application testing, image engineering, and phased deployment of Windows 11 across your endpoint estate. We ensure hardware readiness (TPM 2.0, Secure Boot), resolve application compatibility issues, and execute the upgrade with minimal user downtime.

WHY IT MATTERS

Why Windows 11 Migration matters.

Staying on an older Windows release raises security exposure over time, but the move to Windows 11 is rarely a single switch. Some machines fail the hardware requirements, a few business applications behave differently after the upgrade, and users notice interface changes that nobody warned them about. Without a plan, the work becomes a string of surprise tickets and half-upgraded departments. The teams that struggle are usually the ones that learned about incompatible models and fragile applications only after the first wave had already started.

Good looks like a sorted estate before any upgrade begins. Devices are grouped into ready, ready after a firmware or driver change, and needs replacement. Critical applications have been tested by the people who actually use them. A small pilot group runs on the new build first, and its findings change the runbook before larger waves go out. Users get notice, a booked time and a place to ask questions. Deploris provides the field engineers who run the sessions and the coordination around them, working with your policies, images and management tooling.

SCOPE

Scope of service.

  • 01Hardware compatibility audit against Windows 11 requirements
  • 02Application compatibility testing and remediation
  • 03Windows 11 gold image engineering and GPO configuration
  • 04Phased in-place upgrade or wipe-and-reload execution
  • 05User communication, scheduling, and appointment booking
  • 06Driver and firmware update validation across device models

CHOOSING

Choosing this service.

What to decide before you order, and what sits outside the scope.

In-place upgrade or fresh build

In-place upgrades keep user settings and suit healthy, well managed devices. A wipe-and-reload gives a clean baseline and suits older or cluttered machines, but it needs a reliable data backup step. Many estates use both, decided per device group after the readiness check.

Migration alone or with refresh

If a meaningful share of devices cannot run Windows 11, upgrading the rest and replacing the others as a combined effort can save second visits. Ask for the readiness results first, then decide whether to link this project to a hardware refresh.

Who owns the application risk

Field engineers can test and report, but fixing a vendor application is a different job. Decide who contacts software vendors, who signs off a workaround, and who accepts the risk for applications that cannot be changed before the first wave.

Pick a pilot that is honest

A pilot made only of friendly IT staff hides problems. Include a mix of device models, locations and job roles, including at least one team that depends on specialist software. Tell us who can approve changes to the runbook after the pilot.

Not included

  • Buying Windows licenses, subscriptions or volume agreements is handled between you and your licensing provider.
  • Rewriting or vendor patching of line-of-business software that fails testing is outside field migration scope.
  • Redesigning your device management platform, security policies or identity architecture needs a separate engagement.
  • Repairing hardware that fails for reasons unrelated to the upgrade is quoted separately from the migration itself.

USE CASES

Typical scenarios.

Scenario 01

An insurance company migrating 5,000 endpoints from Windows 10 to Windows 11 before end-of-support, with zero tolerance for claims-processing downtime.

Scenario 02

A hospital network upgrading clinical workstations to Windows 11 while maintaining compliance with medical device software regulations.

Scenario 03

A law firm moving 600 solicitor laptops to Windows 11 with full application compatibility testing for document management and practice management software.

PROCESS

How the work runs.

  1. 1

    Run the readiness check

    We collect hardware and software data from your devices, sort them into readiness groups, and list applications that need testing so you can approve the wave plan before any user is scheduled.

  2. 2

    Prepare and pilot

    The image, settings and runbook are tested on a mixed pilot group. Findings, user feedback and any rollback needs are recorded and the runbook is revised. Pilot users are asked what felt different so the briefing can be improved.

  3. 3

    Upgrade in scheduled waves

    Engineers work through booked sessions by site or team, confirm backups where needed, run the upgrade path chosen for each device group and verify sign-in and key applications.

  4. 4

    Verify and report

    We check completed devices against your target configuration, log any exceptions and deliver a report listing upgraded, deferred and replaced devices with the reason for each. Open items are assigned to a named owner.

FAQ

Frequently asked questions.

What if some of our hardware is not Windows 11 compatible?
We identify incompatible devices during the readiness assessment and recommend whether to upgrade hardware, extend Windows 10 support, or replace the device as part of a concurrent refresh.
Do you test line-of-business applications before migration?
Yes. We build a representative test environment, validate every critical application, and document any issues with recommended fixes before the pilot phase begins.
Can you perform in-place upgrades to reduce downtime?
Where hardware and software compatibility allows, in-place upgrades are our preferred method. Each upgrade typically completes within 60 to 90 minutes per device.
How do you handle user files during the migration?
User data is backed up to a network share or cloud storage prior to migration. After the upgrade, we verify file integrity and restore any data that was not preserved in place.
How do you decide the order of the upgrade waves?
We work with you to balance risk and workload. Low risk groups with common device models often go first after the pilot, while teams with specialist software or tight deadlines go later. Sites that are hard to revisit may be grouped to reduce travel. The wave plan is yours to approve.
What happens to devices that fail the hardware check?
They are listed with the reason for failure, such as the processor, security chip or firmware state. Some can be fixed with a firmware setting, and others need replacement. You choose between replacing them in the same program, deferring them or using a different arrangement. This keeps the schedule realistic and avoids rework.
Will users lose their settings or shortcuts?
In-place upgrades usually keep many user settings, but the interface and some defaults change, so a short briefing is useful. With a fresh build, personalization depends on the profile tooling you use. We agree what must be preserved in writing and test it during the pilot.
