Database Migration Services — Upgrades, Cross-Platform & Cloud Migrations

Quick answer

What does Hurain Technologies build for database migration services?

Hurain Technologies migrates databases with minimal downtime: version upgrades, cross-platform moves (Oracle or SQL Server to PostgreSQL, MySQL to Aurora), on-premise to AWS, Azure or Google Cloud, and consolidations — with schema conversion, replication-based cutover, full data validation and a tested rollback plan.

Overview

What database migration services with Hurain Technologies looks like

A database migration is the riskiest change most companies make to their systems: data can be lost or silently corrupted, applications can break on subtle SQL differences, and a cutover that overruns becomes an outage. We treat migration as an engineering project with rehearsals, not a weekend task.

We assess compatibility first, convert schemas and code, then use continuous replication (native replication, AWS DMS, GoldenGate-style CDC or logical replication) so the new database stays in sync until cutover. That keeps the final switch to minutes rather than hours.

Every migration ends with row counts, checksums and application testing against the new platform — and a rollback path you've actually rehearsed.

Capabilities

Database Migration Services features we deliver

Compatibility assessment

Schema, stored procedures, data types and application SQL reviewed for the target platform.

Schema & code conversion

Tables, indexes, procedures, triggers and functions converted and tested.

Continuous replication

CDC-based sync so source and target stay aligned until cutover.

Data validation

Row counts, checksums and business-rule checks to prove nothing was lost.

Rehearsed cutover

Dry runs, timed runbooks and a tested rollback plan.

Post-migration tuning

Performance tuning on the new platform and 24/7 hypercare.

Use cases

Version upgrades

End-of-life Oracle, SQL Server, PostgreSQL or MySQL versions upgraded safely.

Commercial to open source

Oracle or SQL Server to PostgreSQL to cut licence costs.

On-premise to cloud

Move to RDS, Aurora, Azure SQL or Cloud SQL.

Consolidation

Merge many small databases or servers into fewer, managed ones.

Cost & timeline

How much does database migration services cost and how long does it take?

A first production release typically takes 4–12 weeks depending on size, and a full-featured platform with 2–4 weeks hypercare. Price is driven by scope rather than a fixed rate card — these are the factors that move it most:

Database size and number of schemas
Source and target platforms
Amount of stored procedures and application SQL
Downtime tolerance
Data-validation depth
Number of environments

Our Approach

Our approach to development methodologies

Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your database migration services project.

Agile Scrum

Best for: Evolving products

Two-week sprints with a working demo at the end of each, so database migration services priorities can change as you learn from users.

Kanban

Best for: Continuous delivery & support

A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.

Fixed-scope (Waterfall-style)

Best for: Well-specified builds

Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.

Lean MVP

Best for: New ventures

Build the smallest database migration services release that proves demand, measure it with real users, then invest where the data points.

DevOps & CI/CD

Best for: Every project

Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.

Security-by-design (DevSecOps)

Best for: Regulated & high-value systems

Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.

Why we're different

Hurain Technologies apart: what makes us different

Plenty of agencies can build database migration services. Here is what sets us apart for clients worldwide.

Engineering depth, not a reseller

Your database migration services project is designed and built by our own in-house engineers — no hidden subcontracting chain between you and the people writing code.

Built for your market, not a template

Payments, tax, language and data-protection requirements for your target market are part of the design from day one instead of retrofitted after launch.

Transparent, senior-led delivery

A named project lead, a shared backlog, fortnightly demos and direct Slack access to the engineers — you always know what is being built and why.

Cost advantage without cutting corners

Delivering from India gives clients worldwide senior engineering at a fraction of typical onshore agency rates, with the same code-review, testing and security standards.

You own everything

Source code lives in your repository from the first commit; IP, infrastructure accounts and documentation transfer to you in full.

We stay after launch

Monitoring, updates and a support SLA mean the team that built your product is the team that keeps it running.

Flexible engagement models

How we work with database migration services clients worldwide

Ways to work together, depending on how your team and roadmap are set up.

Model 01

Dedicated Development Team

An extended team of database migration services engineers, QA and architects working exclusively on your product, managed day-to-day by you with our engineering leadership behind them.

Best for: Long-term products and evolving roadmaps

Model 02

Fixed-Cost Delivery

A clearly scoped database migration services build with a defined timeline and price — ideal for a well-specified MVP, integration or launch product.

FAQ

Database Migration Services: frequently asked questions

What is database migration services?

How long does database migration services take?

A first production release typically takes 4–12 weeks depending on size; a full-featured platform with 2–4 weeks hypercare, depending on scope and integrations.

How much does database migration services cost?

Cost depends mainly on database size and number of schemas, source and target platforms, amount of stored procedures and application SQL. Share your requirements and we return a fixed-scope estimate within 5 business days.

How much downtime does a database migration need?

With replication-based migration, usually minutes: the target is kept in sync while you keep working, and only the final switch-over needs a short window.

Can you migrate Oracle to PostgreSQL?

Yes. We convert schemas, PL/SQL and data types, test the application against PostgreSQL, and use replication for a short, rehearsed cutover.

How do you make sure no data is lost?

We validate with row counts, checksums and business-rule checks on every table, and keep a tested rollback path until you sign off.

Do you offer ongoing database support?

Yes. Most clients use a monthly retainer with 24/7 monitoring and on-call response, routine maintenance, patching, tuning and monthly health reports. Coverage scales from a single instance to large multi-platform estates.
