Cloud Migration and Modernization Services for Indian Enterprises
Cloud migration and modernization is the work of physically moving servers, databases, files and applications into AWS, Azure or Google Cloud, and making the changes needed for them to run well there. NTSPL builds the landing zone, runs migrations in planned waves with rehearsed cutovers in Indian regions, and closes each programme with a 90-day optimization phase against the business case.

Cloud Migration & Modernization at a Glance
This family covers the build phase of a cloud programme: the period after the decision to move has been made and before steady-state operations begin. It spans 12 capabilities, from emptying a colocation cage and converting VMware clusters to switching a multi-terabyte Oracle database in a minutes-long window or refactoring an app off MSMQ. Each page is a distinct engagement with its own method, tools and measures, and most programmes use four to six of them together.
NTSPL's migration work follows three rules across all of them. The foundation is built before production workloads arrive. Every move is rehearsed and has a named rollback point. And a migration is not closed until source systems are decommissioned and the first cloud bills match the business case. We deliver on AWS Mumbai and Hyderabad, Azure Central India, South India and West India, and Google Cloud Mumbai and Delhi.
Four Workstreams in a Cloud Migration Programme
Move the estate
Facility exits, hypervisor conversions, workload-led rehosts, file and archive moves, and switches between hyperscalers. These engagements carry servers and data across with rack-aligned or cluster-aligned waves, preserved permissions and tested rollbacks, and they end with hardware wiped, contracts released and source accounts closed.
Data Centre to Cloud Migration
Exit your data centre or colo on a fixed date: rack-by-rack waves, interim links, contract release and decommissioning on AWS, Azure or Google Cloud.
VMware & Hyper V Migration
Move vSphere and Hyper-V VMs to native cloud instances or hosted VMware: driver remediation, boot conversion, licence choices and per-cluster waves.
Server & Workload Migration
Rehost physical and virtual servers per workload: agent-based replication, app-aware cutover, OS fixes and test scripts on AWS, Azure or Google Cloud.
Storage & File Migration
Move NAS, Windows file servers and archives to cloud file and object storage with ACLs kept, delta syncs, tiering and a short final cutover in India.
Cloud to Cloud Migration
Move workloads between AWS, Azure and Google Cloud: service mapping, egress waivers, IAM and IaC rewrites, data transfer and dual-run cutover in India.
Move and adapt applications
Same-engine database moves with change data capture, replatforming onto managed runtimes with configuration-only changes, and bounded refactoring for apps whose code blocks cloud hosting. Each has a strict scope rule so migration-time change does not grow into a rewrite that belongs in a modernization programme.
Database Migration
Move SQL Server, Oracle, MySQL and PostgreSQL to managed cloud databases on the same engine, using CDC replication, validation and short cutover windows.
Application Replatforming
Move apps from VMs to managed runtimes during migration with config-only changes: app services, containers without rewrites, managed caches and databases.
Application Refactoring
Make the targeted code changes an app needs to move: stateless sessions, storage SDKs, managed queues, health checks and identity, without a full rewrite.
Run the programme
The landing zone that workloads land in, the migration factory that sets wave cadence and throughput, and the cutover and hypercare discipline for business-critical go-lives. These are the mechanics that decide whether a 400-server programme takes six months or three years.
Landing Zone Implementation
Build a migration-ready landing zone: account and subscription structure, identity, hub network, guardrails, logging and IaC in Indian regions for CERT-In.
Migration Factory & Waves
Run large migrations as a factory: wave planning, squads, intake gates, runbook templates and weekly throughput tracking on AWS, Azure and Google Cloud.
Cutover & Hypercare
Plan and run migration go-lives: minute-level runbooks, go/no-go gates, rollback points, dress rehearsals and 2-4 weeks of hypercare with exit criteria.
Close the gap to the business case
A fixed 90-day phase after the last wave that removes migration residue such as replication servers and staging disks, right-sizes VMs copied from on-prem, corrects disk tiers, applies licence benefits and sizes the first commitments, then hands a clean cost and performance baseline to operations.
What a Finished Migration Should Show
How NTSPL Migrates onto AWS, Azure and Google Cloud
On AWS, NTSPL uses Control Tower with Landing Zone Accelerator for the foundation, Application Migration Service for server and VMware moves, AWS Transform for VMware wave planning, Database Migration Service with native backup seeding, and DataSync for file data, with Mumbai as primary and Hyderabad for in-country recovery.
On Azure, NTSPL builds on Azure Landing Zones, uses Azure Migrate for VMware, Hyper-V and physical servers, Azure Database Migration Service and Managed Instance link for SQL Server, Azure File Sync for branch file shares, and Azure Hybrid Benefit to carry existing Windows Server and SQL Server licences into Central India and South India.
On Google Cloud, NTSPL starts from the Terraform foundation blueprint with organisation policies and VPC Service Controls, uses Migration Center for inventory, Migrate to Virtual Machines for VMware, AWS and Azure sources, Database Migration Service for MySQL, PostgreSQL and SQL Server, and Storage Transfer Service for file archives into Mumbai and Delhi.

Cloud Migration & Modernization: Frequently Asked Questions
Which migration services does a typical programme need?
A mid-size programme of 150-400 servers usually combines a landing zone, server or VMware migration, database migration, a migration factory for wave cadence, cutover planning for the five or six critical systems, and post-migration optimization. Replatforming or refactoring is added for the 10-20% of apps that justify it.
How is migration different from cloud assessment?
Assessment decides what should move, where and why, and produces reports, scores and a roadmap. Migration builds and executes: it creates the landing zone, replicates servers and data, runs cutovers and decommissions sources. If you do not yet know your target cloud or 6R treatment per app, start with assessment.
Do you migrate onto one cloud or several?
Most clients migrate to one primary cloud, chosen on commercial and skills grounds. We also run cloud-to-cloud moves and support deliberate multi-cloud setups where each workload has a home cloud. We avoid accidental multi-cloud, where two half-used landing zones double the operating effort.
How long does a full migration programme take?
For 100-300 servers, 5-8 months from landing zone to last wave is typical, followed by a 90-day optimization phase. Larger estates run longer, but velocity, not size, sets the end date, which is why we track throughput weekly once the factory is running.
How do you keep migrations compliant with Indian regulations?
Workloads land in Indian regions, logs are kept 180 days in India for CERT-In, and incident paths support its 6-hour reporting rule. We map personal data for DPDP Act 2023 accountability, and for RBI, SEBI or IRDAI regulated entities we align controls and outsourcing records to the relevant framework.
What happens after the migration ends?
We hand over a clean estate: IaC repositories, runbooks, a cost baseline per application and remaining recommendations. Ongoing operations, such as monitoring, patching, backup and cost management, move to your team or to a managed cloud service, which NTSPL also offers.
