Cloud Migration Services in the UK for Telecommunications
Move your telecoms provider to Azure with a proven migration methodology that eliminates risk.
Structured Methodology
Every migration follows a proven framework — assess, plan, migrate, optimise — eliminating guesswork and reducing risk at every stage.
Minimal Downtime
We design migration waves and cutover plans that keep your business running, with most workloads migrated outside business hours.
Optimised from Day One
We do not just lift and shift. Every workload is right-sized and configured for Azure to ensure performance and cost efficiency from launch.
Many telecoms remain tied to ageing on-premise servers that increase operational risk and limit growth. Migrating subscriber records, CDRs, and network telemetry to Azure requires careful planning to avoid disruption, data loss, and extended downtime. A structured migration approach is essential for any telecoms provider making the move to the cloud.
Cloudswitched provides cloud migration services for UK telecoms. We assess your existing infrastructure, map dependencies for OSS/BSS, network monitoring, and billing platforms, and execute a phased migration that minimises risk. Our methodology ensures subscriber records, CDRs, and network telemetry arrives in Azure intact, with rollback plans at every stage and full Ofcom, data retention, and GDPR documentation.
How it works for Telecoms businesses
A clear, structured process from consultation to ongoing support.
1
Discovery & Assessment
We map your entire on-premises estate — servers, dependencies, performance profiles, and compliance requirements — to build a complete picture before designing the migration plan.
2
Wave Planning
Workloads are grouped into migration waves based on complexity, dependencies, and business criticality. Each wave has its own timeline, testing plan, and rollback procedure.
3
Post-Migration Optimisation
After cutover, we monitor performance and costs closely, tuning configurations, right-sizing resources, and addressing any issues that emerge in the live environment.

Zero-Downtime Migration
Phased migration methodology ensures OSS/BSS, network monitoring, and billing platforms and subscriber records, CDRs, and network telemetry move to Azure without disrupting day-to-day operations across your telecoms provider.
Pre-Migration Assessment
Comprehensive discovery of your existing infrastructure, application dependencies, and Ofcom, data retention, and GDPR requirements ensures nothing is missed during planning.
Data Integrity Validation
Automated checksums and validation scripts confirm subscriber records, CDRs, and network telemetry arrives in Azure complete and uncorrupted, with full audit trails for Ofcom, data retention, and GDPR purposes.
Rollback Protection
Every migration phase includes documented rollback procedures, ensuring your telecoms provider can revert to previous state if any unexpected issues arise.

Frequently Asked Questions
Timeline depends on the number of workloads and complexity of OSS/BSS, network monitoring, and billing platforms integrations. Typical telecoms provider migrations run between four and twelve weeks. We provide a detailed timeline during the assessment phase before any commitment.
We design migrations specifically to minimise disruption to OSS/BSS, network monitoring, and billing platforms. Critical telecoms provider systems are migrated during evenings or weekends, with rollback plans at every stage. Most clients experience zero perceptible downtime.
Subscriber records, CDRs, and network telemetry is transferred using encrypted connections with integrity validation at every stage. We maintain parallel environments during cutover, ensuring data is verified in Azure before decommissioning source systems.
Ofcom, data retention, and GDPR compliance is maintained throughout the migration. We document the chain of custody for subscriber records, CDRs, and network telemetry, configure Azure environments to meet regulatory standards before migration begins, and provide compliance evidence for auditors.
We provide a hypercare period of enhanced monitoring and rapid support following migration. This covers performance tuning, user issue resolution, and optimisation of your new Azure environment for telecoms provider workloads.
