Everything you need to know about migrating to Google Cloud and how PrecisionTech delivers end-to-end migration services
.
1
What is the Google Cloud ADAPT migration methodology?
ADAPT is Google Cloud's structured migration framework with four phases: Assess (discover workloads, map dependencies, build TCO business case using Migration Center and Pricing Calculator); Design (architect target Landing Zone, assign migration strategies per workload, plan waves); Deploy (execute migrations using M2VM, DMS, Transfer Service, and Transfer Appliance); Troubleshoot & Optimize (validate cutovers, right-size Compute Engine, procure Committed Use Discounts, modernize where beneficial). PrecisionTech aligns every GCP migration engagement to ADAPT, producing audit-ready documentation at each phase gate.
2
What is Migrate to Virtual Machines (M2VM) and how does lift-and-shift work on GCP?
Migrate to Virtual Machines (formerly Velostrata / Migrate for Compute Engine) is Google Cloud's primary lift-and-shift tool. A lightweight replication agent installs on source servers (physical, VMware, Hyper-V, AWS, Azure). It continuously replicates block-level data to a staging area in your GCP project while production stays live. When ready: run a test clone in Compute Engine, validate, then cut over during a maintenance window — typical downtime under 30 minutes. Supported OS: Windows Server, RHEL, CentOS, Ubuntu, SUSE. PrecisionTech has migrated hundreds of servers via M2VM with zero data loss.
3
How does Google Cloud Database Migration Service (DMS) work?
GCP Database Migration Service migrates databases to Cloud SQL, AlloyDB, or Spanner with minimal downtime using continuous replication. Homogeneous migrations (MySQL→Cloud SQL MySQL, PostgreSQL→Cloud SQL PostgreSQL) use native replication. Heterogeneous migrations (Oracle→PostgreSQL, SQL Server→PostgreSQL) use automated schema conversion plus manual refinement for complex objects. CDC keeps source and target synchronized until cutover. PrecisionTech handles endpoint configuration, schema conversion, data validation, and application connection string updates for every DMS engagement.
4
When should I use Transfer Service vs Transfer Appliance for data migration?
Transfer Service (formerly Transfer Service for on-premises data) moves data over the network from NFS, HDFS, or S3-compatible sources to Cloud Storage at speeds up to 10 Gbps — ideal when you have adequate bandwidth and data volumes under ~100 TB. Transfer Appliance is a ruggedized physical device (up to 480 TB usable) shipped to your data centre — you load data locally, ship it back, and Google ingests into Cloud Storage. Use the appliance when network transfer would exceed 1–2 weeks or bandwidth is limited. PrecisionTech calculates the break-even point during assessment and coordinates appliance logistics end-to-end.
5
What is a GCP Landing Zone and why is it needed before migration?
A GCP Landing Zone is a secure, well-architected multi-project foundation built before workloads migrate. It includes: GCP Organization with folder hierarchy (production, non-production, shared services, security); VPC with subnets, Cloud NAT, and firewall rules; centralized IAM with least-privilege roles; Cloud Logging and Cloud Audit Logs aggregation; Security Command Center activation; billing account structure with budgets and alerts; and Organization Policy constraints (e.g., restrict resource locations to asia-south1 and asia-south2 for India data residency). PrecisionTech deploys Landing Zones using the Google Cloud Foundation Toolkit (Terraform modules) — governance from day one, not bolted on after migration.
6
How does Organization Policy enforce India data residency on GCP?
Organization Policy constraints restrict where GCP resources can be created. For DPDP Act 2023 and RBI compliance, PrecisionTech configures constraints/gcp.resourceLocations to allow only in:asia-south1-locations (Mumbai) and in:asia-south2-locations (Delhi). Additional constraints can enforce: CMEK for Cloud Storage and BigQuery; disable service account key creation; require OS Login for SSH; restrict public IP assignment; and block cross-project service account usage. These policies inherit down the Organization → folder → project hierarchy and cannot be overridden by project admins without org-level permission.
7
How long does a typical GCP cloud migration take?
Timelines vary by scope: SMB (5–20 servers, 1–3 databases) — 2 to 6 weeks including Landing Zone and first-wave cutover. Mid-market (20–100 servers, multiple databases) — 2 to 4 months with phased waves of 15–30 servers each. Enterprise (100+ servers, complex ERP/SAP landscapes) — 6 to 18 months with dedicated program management. Accelerators: M2VM continuous replication (no big-bang), pre-built Landing Zone Terraform modules, and Transfer Appliance for bulk data. PrecisionTech provides detailed timeline estimates during the free Cloud Readiness Assessment.
8
How does PrecisionTech minimize downtime during GCP migration?
PrecisionTech uses: (1) Continuous replication — M2VM keeps source servers live while data streams to GCP; (2) CDC for databases — DMS synchronizes source and Cloud SQL until the final cutover; (3) Test cutovers — full validation clones in Compute Engine before production switch; (4) Blue-green architecture — parallel environments with DNS/load balancer switch; (5) Rollback window — source systems retained 7–14 days post-cutover; (6) Maintenance window scheduling — final switch during agreed off-peak hours. Typical cutover: under 30 minutes per server, under 5 minutes write freeze for databases.
9
Is GCP cloud migration compliant with the DPDP Act 2023?
Yes, when architected correctly. The DPDP Act 2023 requires reasonable security safeguards and, for significant data fiduciaries, data localization for certain categories. PrecisionTech architects GCP migrations with: India-region-only resource constraints (asia-south1, asia-south2); encryption at rest (Google-managed or CMEK via Cloud KMS); encryption in transit (TLS 1.2+); VPC Service Controls for data exfiltration prevention; Cloud Audit Logs for access trails; and documented data processing records. We deliver a DPDP compliance mapping report at migration sign-off, mapping each control to GCP service configurations.
10
Can I migrate from AWS or Azure to Google Cloud?
Yes. M2VM supports source servers running on AWS EC2 and Azure VMs — install the replication agent, replicate to GCP Compute Engine, and cut over. Database Migration Service supports cross-cloud database migrations (AWS RDS, Azure Database → Cloud SQL). Transfer Service can pull from S3-compatible endpoints (including AWS S3) directly into Google Cloud Storage. PrecisionTech has executed AWS-to-GCP and Azure-to-GCP migrations for Indian enterprises seeking BigQuery analytics, GKE Kubernetes leadership, or Vertex AI capabilities unavailable on their current cloud.
11
What migration strategies does Google Cloud recommend besides lift-and-shift?
Beyond rehost (M2VM lift-and-shift), Google Cloud supports: Replatform — move databases to Cloud SQL or AlloyDB, containers to GKE or Cloud Run; Refactor — rebuild as cloud-native microservices on Cloud Run, Cloud Functions, or GKE; Repurchase — replace legacy software with Google Workspace, Chrome Enterprise, or SaaS from Google Cloud Marketplace; Retire — decommission redundant applications identified during Migration Center discovery; Retain — keep workloads on-premises connected via Cloud Interconnect or VPN. PrecisionTech assigns the optimal strategy per workload during the ADAPT Assess phase.
12
What is Google Cloud Migration Center?
Migration Center (formerly StratoZone) is Google's unified discovery and assessment platform. It inventories on-premises and cloud servers — CPU, memory, storage, OS, and utilization — via agentless scanning or CSV import. It generates: right-sized Compute Engine recommendations; TCO comparison (on-premises vs GCP); carbon footprint reduction estimates; and migration wave planning. Migration Center integrates with M2VM for seamless transition from assessment to execution. PrecisionTech uses Migration Center as the discovery backbone for every GCP migration assessment.
13
How does GCP migration compare to AWS migration for Indian businesses?
Both clouds offer mature migration toolsets. Server migration: GCP M2VM vs AWS MGN — both use continuous block-level replication with similar cutover models. Database migration: GCP DMS vs AWS DMS — comparable CDC capabilities; GCP AlloyDB offers superior PostgreSQL performance for demanding workloads. India regions: GCP has Mumbai (2017) and Delhi (2021); AWS has Mumbai (2016) and Hyderabad (2022). Differentiators: GCP leads in Kubernetes (GKE), data analytics (BigQuery), and AI/ML (Vertex AI); AWS has broader service catalogue and larger India enterprise install base. PrecisionTech is authorized partner for both and provides unbiased multi-cloud advisory.
14
How is data secured during GCP migration?
PrecisionTech implements defence-in-depth: Network — Cloud Interconnect or Cloud VPN (IPsec) for replication traffic, never unencrypted public paths for sensitive data; Encryption — M2VM encrypts data in transit and at rest on persistent disks; DMS uses SSL/TLS for database connections; Transfer Service encrypts in transit; Access control — least-privilege IAM roles for migration service accounts; secrets in Secret Manager; Audit — Cloud Audit Logs capture every API call; Isolation — staging environments in dedicated VPC subnets with restrictive firewall rules; Cleanup — replication agents, temporary credentials, and staging resources decommissioned after validation.
15
Can I run hybrid cloud during and after GCP migration?
Yes. Most enterprise migrations are hybrid — some workloads on GCP, others on-premises during transition. Google Cloud supports hybrid via: Cloud Interconnect — dedicated 10 Gbps/100 Gbps private connectivity to Mumbai and Delhi POPs; Cloud VPN — encrypted IPsec tunnels over internet; Anthos — manage GKE clusters on-premises and in cloud with unified control plane; Storage Transfer Service — ongoing sync between on-premises NAS and Cloud Storage; Cloud DNS — split-horizon DNS for gradual traffic migration. PrecisionTech designs hybrid architectures allowing gradual migration at your pace.
16
What happens after migration — how does post-migration optimization work?
Post-migration optimization typically yields 20–40% cost reduction within 60 days. PrecisionTech delivers: (1) Rightsizing — Recommender API insights to downsize over-provisioned VMs from lift-and-shift; (2) Committed Use Discounts — 1-year or 3-year CUDs for stable workloads after 2–4 weeks of usage data; (3) Spot VMs — fault-tolerant batch workloads on preemptible capacity; (4) Storage lifecycle — Cloud Storage class transitions (Standard → Nearline → Coldline → Archive); (5) Architecture modernization — containerize monoliths to GKE/Cloud Run, migrate self-managed DBs to Cloud SQL; (6) Monitoring — Cloud Monitoring dashboards, billing alerts, and monthly executive cost reports.
17
What is PrecisionTech's GCP migration methodology?
PrecisionTech follows Google's ADAPT framework with six delivery phases: Assess (Week 1–2) — free Cloud Readiness Assessment, Migration Center discovery, TCO analysis, strategy assignment; Design (Week 2–3) — Landing Zone architecture, wave plan, compliance mapping; Mobilize (Week 3–4) — deploy Landing Zone, install M2VM agents, configure DMS, establish Interconnect/VPN; Migrate (Week 4–12+) — execute waves, test cutovers, production switch; Validate — functional, performance, and security testing per wave; Optimize (ongoing) — rightsizing, CUDs, managed services activation. Weekly status reports and Migration Center dashboards keep stakeholders informed.
18
Is GCP cloud migration suitable for regulated industries in India?
Yes. BFSI — RBI permits public cloud for production with appropriate controls; asia-south1 satisfies data localization; PCI-DSS via compliant GCP services. Healthcare — GCP offers HIPAA-eligible services; PrecisionTech configures encryption, audit logging, and access controls for clinical workloads. SEBI-regulated — market infrastructure can run on GCP India regions with documented controls. Government — GCP is empanelled for Government of India cloud services. PrecisionTech delivers audit-ready compliance documentation mapped to your regulatory framework at every migration sign-off.

20
What VMware-to-GCP migration options are available?
Three primary paths: (1) M2VM lift-and-shift — install replication agent on VMware VMs, replicate to Compute Engine, cut over (fastest, preserves VM-level fidelity); (2) Google Cloud VMware Engine — run native VMware SDDC (vSphere, vSAN, NSX) on Google bare-metal in asia-south1 — ideal for gradual migration with vMotion; (3) Refactor to containers — migrate workloads to GKE using Migrate to Containers for long-term cloud-native operation. PrecisionTech evaluates VMware estate size, licensing constraints, and timeline to recommend the optimal path during assessment.
21
How much does GCP cloud migration cost with PrecisionTech?
Migration cost depends on scope — number of servers, database complexity, data volume, and compliance requirements. PrecisionTech migration engagements typically start from
₹12,999/month for managed migration programs on SMB estates, scaling to enterprise programs for large data centre exits. Google Cloud migration tools (M2VM, DMS, Transfer Service) have their own usage charges billed by Google. We provide a fixed-price quote after the free assessment — no surprise costs. Contact
