Microsoft Azure Migration India — On-Premises to Azure Cloud

Ogma plans and executes Microsoft Azure cloud migrations for Indian enterprises — from server lift-and-shift using Azure Migrate and ASR, to database migration to Azure SQL, and application modernisation to AKS or App Service. Defined RTO, minimal downtime, and full post-migration managed service.

Azure Migration Services

Ogma's Azure migration practice covers every phase — from initial discovery through production cutover and post-migration operations.

Azure Migration Assessment

Azure Migrate assessment: discover on-premises servers, storage, and SQL instances, calculate Azure readiness, estimate right-sized VM/PaaS equivalents, and produce a total cost of ownership (TCO) comparison.

Lift & Shift (Rehost)

Server rehost to Azure VMs using Azure Site Recovery (ASR) — replicate on-premises VMs (VMware, Hyper-V, physical) to Azure with continuous replication and minimal cutover downtime. Zero application changes required.

Database Migration

SQL Server to Azure SQL Managed Instance, Azure SQL Database, or Azure SQL on VMs using Azure Database Migration Service (DMS). Ogma handles schema assessment, data migration, and application connection string changes.

Application Modernisation

Containerise .NET and Java applications for Azure Kubernetes Service (AKS) or Azure App Service. Ogma refactors stateful applications to stateless microservices — enabling autoscaling and PaaS-managed infrastructure.

Security & Compliance Post-Migration

Post-migration security: Defender for Cloud CSPM setup, network security group review, Azure Policy assignment, Key Vault for secrets management, and compliance baseline (CIS Azure, NIST).

Azure Cost Governance

Post-migration: implement Azure Cost Management budgets and alerts, Reserved Instance purchasing for stable workloads, tagging policy for cost allocation, and monthly cost review with Ogma.

Why Ogma for Azure Migration

Azure-Certified Migration Team

Ogma's engineers hold AZ-104, AZ-305, and AZ-500 certifications. Every migration follows Microsoft's Cloud Adoption Framework (CAF) and Well-Architected Framework (WAF) principles.

Minimal Downtime Approach

ASR continuous replication keeps cutover windows under 10 minutes per VM. Database migrations use online DMS with near-zero downtime. Ogma batches cutovers to avoid business-hours impact.

Full Post-Migration MSP

Most migration customers transition to Ogma's Azure Managed Service at go-live — covering monitoring, patching, backups, cost optimization, and 24x7 incident response.

How It Works

1
Discovery & Assessment

Azure Migrate agents deployed on-premises. Full inventory of VMs, dependencies, storage, and SQL instances. Azure readiness report with right-sized recommendations and TCO estimate.

2
Migration Design

Ogma produces a migration wave plan — grouping workloads by dependency, priority, and business criticality. Azure network design, security baseline, and rollback procedures documented.

3
Test Migration

Non-disruptive test failover to an isolated Azure VNet. Application and database validation against production data snapshot. Sign-off before production cutover.

4
Production Cutover

Planned failover during agreed maintenance window. Final delta replication, cutover, DNS update, and validation. On-premises VMs placed in powered-off state (not deleted) for parallel-run period.

5
MSP Handover

Ogma transitions to Azure Managed Service: monitoring dashboards, alerting, patch schedules, backup policies, Reserved Instance purchasing, and regular cost reviews.

Migration Approach Reference

Migration Approach Suitable For Downtime Azure Target Timeline
Lift & Shift (ASR) Most server workloads Minutes (cutover) Azure VMs 2–4 weeks
Database DMS SQL Server, PostgreSQL, MySQL Hours–minutes Azure SQL MI / DB 1–3 weeks
Re-platform IIS/.NET apps, Java apps Hours Azure App Service / AKS 4–8 weeks
Refactor/Modernise Custom apps, microservices Varies AKS, Functions, Cosmos DB 2–6 months
Azure Virtual Desktop Remote desktop workloads None (parallel) AVD host pools 1–2 weeks

Frequently Asked Questions

Discovery — using Azure Migrate, Ogma installs lightweight discovery agents on your on-premises VMware/Hyper-V or physical servers. The tool inventories all VMs, dependencies, storage, and SQL instances, then produces an Azure readiness report with right-sized VM recommendations and cost estimates.

ASR continuously replicates your on-premises VM to Azure — changes (delta replication) sync every few minutes. When you're ready to cut over, you initiate a planned failover — Azure starts the replicated VM in seconds. Total cutover downtime is typically under 10 minutes per VM.

Azure SQL Managed Instance is a PaaS service — Microsoft manages patching, backups, and HA automatically. Azure SQL on VM is IaaS — you manage the OS and SQL Server. Managed Instance is better for most SQL Server workloads (especially those using SQL Agent, CLR, or linked servers) but requires verifying application compatibility. Ogma's assessment identifies any blockers.

A 50-server ASR-based lift-and-shift migration typically takes 4–6 weeks: 1 week assessment, 1 week Azure environment setup, 2 weeks replication and test failover, 1 week production cutover (batched by dependency group). Ogma provides a detailed project plan after the assessment.

Yes — Ogma designs Azure network topology: VNet design (hub-and-spoke or flat), site-to-site VPN to your on-premises DC, ExpressRoute circuit procurement and peering configuration, network security groups, and Azure Firewall for internet egress.

Ogma recommends a parallel-run period (typically 2–4 weeks) where both on-premises and Azure run simultaneously before decommissioning on-premises servers. Ogma provides a decommissioning checklist and can assist with data archiving before physical server disposal.

Yes — Ogma's Azure Managed Service (AMS) covers post-migration operations: VM monitoring, patching, backup management, cost optimization, security posture, and 24x7 incident response. Most migration customers transition to AMS at go-live.
