Cloud Migration · Zero Downtime

Cloud Migration & Workload Modernization Services

Aging on-premise servers expose your business to hardware failures, power outages, and catastrophic ransomware loss. Exelon Circuits migrates legacy desktop applications, database servers, and corporate IT workloads into secure AWS and Azure cloud environments.

We orchestrate smooth, phased cutovers with continuous real-time data replication, ensuring your staff and customer-facing portals experience zero operational disruption during migration.

Cloud migration capabilities

Comprehensive technical solutions engineered for security, reliability and measurable business outcomes.

On-Premise to Cloud Re-hosting (Lift & Shift)

Rapidly migrating physical VMware or Hyper-V virtual machines directly to cloud instances with minimal code changes.

Live Database Migration & Replication

Replicating SQL Server, Oracle, and PostgreSQL databases to the cloud with real-time sync until the final cutover.

Legacy ERP & Accounting Cloudification

Migrating desktop Tally, custom accounting, and manufacturing inventory into secure, multi-branch accessible cloud environments.

Application Containerization (Docker)

Refactoring legacy monolithic server applications into lightweight, containerized microservices running on cloud nodes.

File Server & NAS Cloud Synchronization

Transferring terabytes of local engineering CAD files, scans, and documents to AWS S3 and Azure Blob with tiered archiving.

Zero-Downtime Weekend Cutover

Scheduling DNS updates and final delta synchronizations during off-hours so business resumes seamlessly on Monday.

Post-Migration Performance Tuning

Optimizing cloud compute sizes, database query indexes, and caching layers to guarantee superior speed post-migration.

Migration Security & Access Control

Locking down cloud network perimeters with multi-factor authentication, VPNs, and encrypted storage volume baselines.

On-Premise Server to AWS & Azure Migration Pipeline

Who needs professional cloud migration

Organizations looking to eliminate fragile on-premise hardware dependencies:

Multi-Branch Retailers & Distributors

Centralizing branch inventory and billing onto cloud-hosted databases for real-time visibility

Manufacturing Facilities

Moving production planning and dispatch servers off vulnerable physical factory floor machines

Professional Services & Accounting Firms

Providing remote, highly secure work-from-anywhere access to tax and client bookkeeping records

Hospitals & Medical Laboratories

Migrating aging PACS servers and historical lab records to durable cloud archival storage

Our 5-phase migration framework

A disciplined, transparent delivery sequence ensuring predictable timelines and verified deliverables.

1

Infrastructure Discovery & Dependency Mapping

Cataloging all server applications, database sizes, network ports, and vendor software licenses.

2

Target Cloud Architecture Design

Configuring secure target VPCs, compute instances, database engines, and storage volumes in AWS or Azure.

3

Pilot Migration & Dry-Run Testing

Performing an initial test migration in an isolated cloud staging sandbox to validate application performance.

4

Delta Sync & Production Cutover

Streaming live database changes and switching production traffic during an approved weekend maintenance window.

5

Post-Cutover Hypercare

Providing dedicated 24/7 on-call engineers for 14 days post-migration to resolve any immediate user issues.

What Cloud Migration Costs

Migration projects are quoted as a transparent, fixed-price milestone engagement:

Total volume of data (gigabytes or terabytes) requiring cloud transfer
Number of server operating systems and database instances being migrated
Level of application refactoring required (simple lift-and-shift vs containerization)
We provide an itemized migration plan with a guaranteed fixed-price estimate following our discovery audit.

We build software, networks, and databases ourselves, enabling us to fix complex database driver incompatibilities on the fly

Frequently Asked Questions

Clear answers regarding deployment timelines, technical scope, and ongoing support.

No. During the initial data copy, your existing on-premise systems remain 100% active. We stream incremental changes in the background and execute the final cutover during a scheduled weekend maintenance window.
