1.8 Million user AgriTech Platform migrates from GCP to AWS with Zero Downtime

DeHaat is a fast-growing Agri-Tech start-up offering AI-enabled, end-to-end farming solutions across 12 states, connecting 1.8M+ farmers through 11,000+ centers and 503 FPOs with crop advisory for 30+ crops.

The Problem Statement

Following the acquisition of Agricentre, DeHaat faced a complex infrastructure challenge. Agricentre operated on Google Cloud Platform (GCP) while DeHaat's core infrastructure was on Amazon Web Services (AWS). The organization needed to migrate the entire Agricentre workload from GCP to AWS in a live production environment without losing any database records, disrupting active users, or causing downtime.  

Challenges

Live Environment Migration

Migrating production workloads with thousands of active users without any service interruption or downtime.

Database Migration Complexity

Transferring large-scale databases while handling incoming GCP traffic and maintaining real-time data consistency.

User Session Preservation

Applications had logged-in user base that needed to remain intact during migration without forcing re-authentication.

AWS DMS Restoration Issues

Configured and optimized Database Migration Service (DMS) for seamless replication with minimal lag, ensuring uninterrupted data flow and improved system reliability.

Rollback Strategy

Developing fail-safe rollback mechanisms in case of migration failure while ensuring data consistency.

User Base Maintenance

Maintaining active user sessions and preventing any disruption to the logged-in user experience during cutover.

Architecture from Scratch

Designing and implementing complete AWS architecture from ground up to match GCP functionality. 

Application Dependencies

Managing complex microservices with interdependencies while preserving all integrations.

Solutions

Comprehensive Planning & Multiple Dry Runs

Created detailed migration plans and conducted multiple dry runs to identify what could work and what couldn’t before production migration. 

Architecture Design from Scratch

Designed complete AWS infrastructure architecture from ground up, ensuring all GCP functionalities were replicated. 

Infrastructure as Code (IaC) Implementation

Leveraged IaC for automated infrastructure provisioning, enabling consistent deployments and rapid rollback capability. 

CI/CD Pipeline Automation

Implemented automated CI/CD pipelines for seamless migration.

AWS DMS Configuration

Configured Database Migration Service with continuous replication to maintain data consistency between GCP and AWS. 

Continuous Monitoring Setup

Established detailed monitoring systems providing better visibility into migration progress and system health. 

User Session Management

Implemented strategies to preserve logged-in user sessions during migration with modifications to handle active users.  

Real-time Replication

Set up continuous data replication ensuring databases remained synchronized during migration period.

Outcomes

100% uptime maintained – complete migration achieved without any service interruption

99%+ data migration rate with 100% integrity and zero data loss

100% user base preserved – seamless migration with active user sessions intact

Immediate issue resolution capability with 24/7 monitoring

Fail-safe mechanisms in place throughout migration period ensuring business continuity
