Cloud Migration
Services
Move your workloads, applications, and data to the cloud with zero downtime and zero surprises — whether you are migrating from on-premises, co-location, or between cloud providers.
Move your workloads, applications, and data to the cloud with zero downtime and zero surprises — whether you are migrating from on-premises, co-location, or between cloud providers.
IDC research shows that 70% of cloud migration projects exceed their original timeline and budget, often due to inadequate discovery, underestimated dependencies, and insufficient testing — turning a 3-month project into a 12-month ordeal.
Poorly planned cutovers result in extended outages that damage customer trust and revenue. A single hour of downtime for an e-commerce platform can cost over £100,000 — and the reputational damage is often far greater.
Migrating terabytes of data across networks introduces risks of corruption, partial transfers, and synchronisation failures. Without proper validation checksums and delta-sync strategies, critical data can be lost or compromised during the transition.
Legacy applications often have undocumented dependencies on specific OS versions, network configurations, or hardware. Discovering these mid-migration causes cascading delays and forces difficult decisions about refactoring versus workarounds.
We do not believe in one-size-fits-all migrations. Every workload is assessed individually and matched to the optimal migration strategy — whether that is a straightforward lift-and-shift, a re-platform to managed services, a full modernisation to cloud-native architecture, or a hybrid approach. Our methodology has been refined across dozens of enterprise migrations, ensuring predictable timelines, minimal disruption, and a clear path to cloud-native excellence.
Comprehensive inventory of servers, applications, databases, and dependencies using automated discovery tools (Azure Migrate, AWS Application Discovery, CloudSphere) with TCO analysis and risk scoring.
Rapid migration of workloads to cloud VMs with minimal changes, ideal for time-sensitive migrations where speed matters more than optimisation. Includes automated server replication and orchestrated cutovers.
Move workloads to managed cloud services (e.g., Azure SQL, RDS, App Service) for reduced operational overhead without rewriting application code. Balances modernisation benefit with migration speed.
Transform monolithic applications into cloud-native microservices using containers, serverless functions, and managed APIs. Maximises cloud benefits but requires deeper investment in development.
Design and implement hybrid environments connecting on-premises data centres with cloud platforms via secure VPN or dedicated connections (ExpressRoute, Direct Connect) for workloads that cannot fully migrate.
Migrate SQL Server, Oracle, MySQL, PostgreSQL, and NoSQL databases to cloud-managed equivalents with minimal downtime using Azure DMS, AWS DMS, or GCP Database Migration Service with continuous replication.
We deploy automated discovery agents to catalogue your entire IT estate — servers, applications, databases, network flows, and dependencies. This produces a complete migration inventory with TCO comparison, risk assessment, and a recommended migration strategy for each workload.
Each workload is assigned to a migration wave based on complexity, dependencies, and business priority. We produce detailed runbooks for each wave covering target architecture, migration method, cutover procedure, rollback plan, and success criteria with sign-off checkpoints.
We provision the target cloud environment using Infrastructure as Code — networking, identity, security policies, monitoring, and governance guardrails. The landing zone follows Well-Architected principles and is validated through automated compliance checks before any workloads land.
Workloads are migrated in planned waves, starting with low-risk, non-critical systems. Each migration includes pre-migration testing, data synchronisation verification, performance benchmarking, and user acceptance testing before the final cutover.
Production cutovers are executed during pre-agreed maintenance windows with dedicated war-room support. DNS switchovers, load balancer updates, and connection string changes are orchestrated in sequence with automated health checks validating each step.
Post-migration, we conduct a hypercare period of 2-4 weeks with enhanced monitoring and rapid response. We then optimise the cloud environment (rightsizing, reserved instances, performance tuning) and coordinate the secure decommissioning of legacy infrastructure.
Organisations migrating to the cloud achieve 20-30% total cost of ownership reduction by eliminating data centre costs, reducing hardware refresh cycles, and leveraging pay-as-you-go pricing models.
Post-migration, organisations accelerate their release velocity by up to 65% by leveraging managed services, serverless computing, and automated CI/CD pipelines that were impossible on legacy infrastructure.
94% of organisations report improved security after migrating to the cloud, benefiting from cloud-native security tools, automated patching, encryption by default, and centralised identity management.
By migrating to managed services and platform-as-a-service offerings, organisations reduce operational overhead by 55% — freeing engineering teams from patching, scaling, and infrastructure maintenance.
A UK private healthcare group operating 12 clinics was running 45 physical servers across two ageing data centres with end-of-life hardware, escalating maintenance contracts (over £180,000/year), and growing NHS DSPT compliance requirements they could not meet with their current infrastructure. Their patient records system, booking platform, and clinical reporting tools needed to migrate without any disruption to patient care.
TotalCloudAI conducted a 3-week discovery using Azure Migrate, identifying all 45 servers, 8 SQL Server databases, and 200+ application dependencies. We designed a phased migration across 4 waves over 10 weeks. Non-critical systems (intranet, file shares, development environments) were migrated first via lift-and-shift. The patient records system was re-platformed to Azure SQL Managed Instance with continuous data sync. The booking platform was modernised to Azure App Service with Azure Front Door. All data was encrypted with customer-managed keys, and we implemented Azure Policy to enforce NHS DSPT controls.
