End-to-end Windows Server migrations from planning and scoping to execution and post-migration support — with zero data loss, minimal downtime, and full role and application continuity.
Windows Server migrations are high-stakes projects. A failed migration means business downtime, potential data loss, and hours of emergency remediation. Most failures happen because migrations are under-planned — the applications, dependencies, and data flows that rely on the server aren't fully mapped before a single change is made.
HAZON UNITY takes a structured approach: thorough pre-migration assessment, documented migration plan, staged execution with validation checkpoints, and a clear rollback path at every step. Our track record includes migrating environments from Windows Server 2007 through to 2019 and 2022 — including Active Directory, IIS, SQL Server, Crystal Reports environments, VoIP, and line-of-business applications.
We don't just migrate the OS — we migrate everything that depends on it. Every role, every application, every integration point is identified, tested on the new environment, and validated before the old server is decommissioned. Then we monitor and support the new environment for 30 days post-migration.
Structured, tested, documented — every migration step managed end to end.
Thorough pre-migration assessment covering all server roles, installed applications, services, scheduled tasks, and dependencies — before a single change is made.
AD forest and domain migrations, trust configurations, user and group migrations, and permission structure preservation with full validation before cutover.
Migrate IIS websites, application pools, web.config, SSL certificates, and web configurations to the new environment — tested and validated for every deployed application.
SQL Server upgrades and migrations with compatibility level testing, job and agent migration, linked server reconfiguration, and application connectivity validation.
Test, remediate, and validate all business-critical applications against the new server environment before cutover — no surprises on go-live day.
Managed cutover with documented rollback plan, post-migration monitoring, issue resolution, and 30-day support period to ensure a stable, well-bedded environment.
Windows Server 2008 R2 and 2012 are end-of-life — no more security patches. We migrate your workloads before the risk becomes critical, with a clear plan and timeline.
Combine your hardware refresh with a server OS upgrade for a complete infrastructure overhaul — minimising disruption by doing both at once with careful planning.
Outgrown your original server setup? We right-size and modernise your infrastructure to match your current workload and give you room to grow.
Industry compliance frameworks often require current server OS versions. We make the upgrade process structured, documented, and auditable.
