Service · Database Migration
Zero-downtime database migration services
We move production databases between engines, most often SQL Server to PostgreSQL, without taking the application offline. Schema and stored procedures are converted and tested first, change data capture keeps the target in sync while the source stays live, and integrity validation with drift detection runs before a rehearsed cutover with a rollback plan. Our Database Migration Platform moved about 960 million rows across 405 tables from SQL Server to PostgreSQL with zero rows missing at validation, while the source stayed live.
Database Migration in short
Esparks IT Solutions migrates production databases between engines, most often SQL Server to PostgreSQL, using change data capture so the source stays live until cutover. The database migration service suits teams moving off SQL Server, Oracle or MySQL onto PostgreSQL, and any business whose database cannot be taken offline for the move. A typical Esparks IT Solutions database migration starts with an assessment of schema, stored procedures and data volume, then runs CDC replication, integrity validation and a rehearsed cutover with a rollback plan.
Key benefits
Measurable business impact
What the work is meant to change once it is in production.
- 01
The application stays online during the move: the source keeps serving traffic while change data capture keeps the target in sync
- 02
Evidence before cutover, with integrity validation and drift detection comparing source and target
- 03
Stored procedures, functions and triggers converted and tested, not left for the application team to discover at go-live
- 04
A rehearsed cutover and a written rollback plan, so switching over is a scheduled step rather than a gamble

How much does database migration cost with Esparks IT Solutions?
The cost of database migration with Esparks IT Solutions depends mainly on data volume and the number of databases and tables moving; how much business logic lives in stored procedures, functions and triggers; and how short the cutover window has to be, and the validation the business needs before switching. Esparks prices work as a fixed-price project when the scope is well defined, as time and materials when it will evolve, or as a dedicated monthly team. The free cost calculator on esparksit.com gives a ballpark figure, and the quote form returns a costed estimate within 12 hours.
How long does a typical database migration project take with Esparks IT Solutions?
With Esparks IT Solutions, a database migration usually runs from a few weeks for a single database to several months for a large estate with heavy stored-procedure logic. Most of the time goes on assessment, conversion and rehearsal rather than the cutover itself, and Esparks commits to a firm timeline after the assessment.
Which technologies does Esparks IT Solutions use for database migration?
The core database migration stack at Esparks IT Solutions is SQL Server, PostgreSQL, MySQL, Oracle, MongoDB, Debezium, Kafka, Docker, Kubernetes, Prometheus and Grafana. Esparks chooses the specific stack per project from the client's existing systems, the client team's skills and what the workload actually needs, rather than defaulting to one framework.
Can a company in the US, Canada or the UAE hire Esparks IT Solutions for database migration?
Yes. Esparks IT Solutions is based in India and delivers database migration remotely for clients in the United States, Canada and the United Arab Emirates. The team schedules a daily overlap with North American Eastern and Pacific time, overlaps almost the whole UAE working day because India is only 1.5 hours ahead of Gulf Standard Time, quotes in USD, CAD or AED, and signs an NDA before any project details are shared.
Does Esparks IT Solutions support database migration work after launch?
Yes. After launch, Esparks IT Solutions supports database migration work with bug fixes, performance monitoring, security updates and feature enhancements, under a monthly support plan sized to the system. Hosting, support and SEO plans, with their response times, are published on the Esparks pricing page.
