Move to the Cloud With Confidence and Minimal Downtime

Migrating to the cloud is one of the most impactful infrastructure decisions a business can make — but it's also one of the riskiest if not planned and executed properly. Renux Technologies provides end-to-end cloud migration services that move your applications, databases, and data from on-premise servers, legacy hosting providers, or other cloud platforms to modern cloud infrastructure. We handle every stage of the migration — from initial assessment and strategy through execution and post-migration optimisation — ensuring minimal downtime, zero data loss, and immediate performance benefits.

Every migration begins with a thorough assessment of your current infrastructure, application dependencies, data volumes, and business requirements. We map every component — servers, databases, storage, networking, DNS, email, cron jobs, background workers, and third-party integrations — to ensure nothing is missed. Based on this assessment, we recommend the most appropriate migration strategy: lift-and-shift for straightforward moves, re-platforming for applications that can benefit from managed cloud services, refactoring for applications that need architectural improvements, or a complete rebuild for legacy systems that won't translate well to cloud environments.

Data migration is the most critical and sensitive phase of any cloud migration. We implement comprehensive data migration plans that include full database exports, incremental synchronisation during the transition period, data integrity validation at every step, and automated comparison tools that verify every row and file has been transferred correctly. DNS cutover is carefully planned and executed during low-traffic windows, with TTL values pre-reduced to minimise propagation delays. We maintain the legacy environment in parallel for an agreed period after migration, providing an immediate rollback path if any issues are discovered.

Post-migration, we don't just walk away. We perform thorough optimisation of your new cloud environment — right-sizing instances based on actual usage data, implementing auto-scaling to handle traffic variations, configuring CDN and caching layers, and establishing monitoring and alerting. We also provide a detailed cost analysis comparing your pre-migration and post-migration infrastructure costs, with recommendations for further savings through reserved instances, spot instances, or architectural optimisations.

What's Included

  • Migration Assessment: Comprehensive audit of your existing infrastructure, application architecture, dependencies, data volumes, compliance requirements, and performance baselines
  • Strategy Selection: Expert recommendation on the optimal migration approach — lift-and-shift, re-platform, refactor, or rebuild — based on your application, timeline, and budget
  • Data Migration Planning: Detailed data migration plan covering databases, file systems, object storage, and application state with integrity verification at every step
  • Application Migration: Server provisioning, application deployment, configuration migration, and environment variable transfer to the target cloud platform
  • Database Migration: Full and incremental database migration with schema compatibility validation, data integrity checks, and replication during the transition period
  • DNS Cutover: Carefully planned DNS transition with pre-reduced TTL values, staged cutover, and monitoring to verify traffic is routing correctly to the new infrastructure
  • Testing & Validation: Comprehensive post-migration testing including functional testing, performance benchmarking, load testing, and data integrity verification
  • Rollback Planning: Documented rollback procedures with the legacy environment maintained in parallel for an agreed period, ensuring immediate recovery if issues arise
  • Post-Migration Optimisation: Instance right-sizing, auto-scaling configuration, caching implementation, and cost optimisation based on actual usage patterns
  • Cost Analysis: Detailed comparison of pre-migration and post-migration costs with recommendations for reserved instances, savings plans, and architectural optimisations

Migration Types We Handle

  • VPS to Cloud: Moving from traditional VPS providers (Hostgator, GoDaddy, Bluehost) to scalable cloud infrastructure on AWS, GCP, or Azure
  • On-Premise to Cloud: Migrating physical servers and local infrastructure to cloud environments, including hybrid cloud configurations
  • Cloud-to-Cloud: Moving between cloud providers (e.g., AWS to GCP, Azure to AWS) for cost, performance, or compliance reasons
  • Monolith to Microservices: Decomposing monolithic applications into containerised microservices during migration, leveraging Kubernetes or managed container services
  • Shared Hosting to Cloud: Upgrading from shared hosting environments to dedicated cloud infrastructure with proper isolation, security, and scalability
  • Legacy Platform Migration: Moving from end-of-life platforms (Windows Server 2012, PHP 5.x, Python 2.x) to modern, supported environments

Tools & Platforms

We leverage cloud-native migration tools and proven methodologies to ensure efficient, reliable migrations:

  • Cloud Platforms: AWS, Google Cloud Platform, Microsoft Azure, DigitalOcean, Hetzner Cloud
  • Migration Tools: AWS Migration Hub, AWS DMS (Database Migration Service), Google Migrate, Azure Migrate, rsync, pg_dump/pg_restore
  • Infrastructure as Code: Terraform, CloudFormation, Ansible for provisioning target environments
  • Containerisation: Docker, Kubernetes for containerising applications during migration
  • Data Transfer: AWS DataSync, Google Transfer Service, rclone, custom migration scripts
  • Monitoring: CloudWatch, Stackdriver, Datadog for post-migration monitoring and validation

Our Migration Process

1. Discovery & Assessment

We audit your entire infrastructure — servers, databases, storage, networking, cron jobs, background processes, third-party integrations, and DNS. We document dependencies, measure performance baselines, and calculate data volumes to build a comprehensive migration plan.

2. Strategy & Planning

Based on the assessment, we recommend a migration strategy, select the target cloud platform and services, design the target architecture, and create a detailed migration timeline with clearly defined milestones, testing checkpoints, and rollback criteria.

3. Execution & Testing

We execute the migration in phases — starting with non-critical systems, then databases and data, and finally production applications. Each phase includes thorough testing and validation before proceeding to the next. DNS cutover is performed during a planned maintenance window.

4. Optimisation & Handover

After migration, we monitor the new environment closely for two to four weeks, optimise resource allocation based on actual usage, implement auto-scaling and caching, and hand over full documentation of the new infrastructure to your team.
