Introduction<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What this service is<\/h3>\n\n\n\n<p><strong>Migrate to Containers<\/strong> is a Google Cloud migration service that helps you <strong>convert virtual machine (VM)-based applications into containers<\/strong> and generate <strong>Kubernetes resources<\/strong> so you can run them on <strong>Google Kubernetes Engine (GKE)<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">One-paragraph simple explanation<\/h3>\n\n\n\n<p>If you have an app running on a VM (for example, in VMware or on a cloud VM) and you want to move it to Kubernetes without rebuilding everything from scratch, <strong>Migrate to Containers<\/strong> analyzes the VM, containerizes what\u2019s needed, and produces deployable artifacts (container images and manifests) to run the app on GKE.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">One-paragraph technical explanation<\/h3>\n\n\n\n<p>Technically, Migrate to Containers uses a set of migration components (deployed into a GKE cluster) to discover a source workload, perform an assessment, and execute a conversion pipeline that typically outputs <strong>container images<\/strong> (stored in a registry such as Artifact Registry) and <strong>Kubernetes YAML<\/strong> (Deployments\/Services, and sometimes volumes and other resources). It\u2019s designed for <strong>application modernization via re-platforming<\/strong> (VM \u2192 container on Kubernetes), not for lift-and-shift VM moves (that\u2019s typically <strong>Migrate to Virtual Machines<\/strong>).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What problem it solves<\/h3>\n\n\n\n<p>Many organizations want Kubernetes benefits (standardized deployments, scaling, rolling updates, better portability) but have a large VM estate. Rewriting apps is costly and slow. <strong>Migrate to Containers<\/strong> helps teams start modernizing faster by providing a structured, tool-assisted path from VM workloads to containers, with assessments and repeatable migration execution.<\/p>\n\n\n\n<blockquote>\n<p>Naming note (verify in official docs): <strong>Migrate to Containers<\/strong> is the current Google Cloud name for what was previously branded as <strong>Migrate for Anthos<\/strong>. The scope remains VM-to-container modernization targeting Kubernetes\/GKE.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">2. What is Migrate to Containers?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Official purpose<\/h3>\n\n\n\n<p>Migrate to Containers is intended to <strong>modernize VM-based applications<\/strong> by converting them to container-based workloads runnable on Kubernetes\u2014most commonly on <strong>Google Kubernetes Engine (GKE)<\/strong>.<\/p>\n\n\n\n<p>Official landing page: https:\/\/cloud.google.com\/migrate\/containers<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Core capabilities<\/h3>\n\n\n\n<p>At a high level, Migrate to Containers supports the lifecycle of VM-to-container modernization:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Discovery and assessment<\/strong> of source workloads (what is running on the VM, dependencies, feasibility signals).<\/li>\n<li><strong>Automated conversion<\/strong> of VM workloads into container images.<\/li>\n<li><strong>Generation of Kubernetes deployment artifacts<\/strong> for GKE (and Kubernetes generally).<\/li>\n<li><strong>Repeatable migration execution<\/strong> for multiple workloads (useful for migration waves).<\/li>\n<\/ul>\n\n\n\n<blockquote>\n<p>Supported source environments and OS\/app compatibility vary.

Top Use Cases and Scenarios<\/h2>\n\n\n\n<p>Below are realistic use cases for Migrate to Containers. Exact feasibility depends on workload characteristics and current support matrices (verify in official docs).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1) VM-based web app to GKE (stateless)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: Web app runs on a VM with manual deploys and inconsistent environments.<\/li>\n<li><strong>Why this service fits<\/strong>: Converts runtime and filesystem into a container image and generates Kubernetes manifests.<\/li>\n<li><strong>Example<\/strong>: A Debian VM running Nginx + a Node.js app is migrated to GKE and exposed via a LoadBalancer Service or Ingress.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2) Standardizing deployments across teams<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: Different teams deploy apps differently (SSH + scripts, custom init scripts, etc.).<\/li>\n<li><strong>Why this service fits<\/strong>: Produces Kubernetes artifacts that can be integrated into GitOps pipelines.<\/li>\n<li><strong>Example<\/strong>: 30 internal tools are migrated and deployed via a standardized Helm\/Kustomize + CI\/CD workflow (post-migration refinement).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3) Data center exit for VMware estates<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: Large VMware footprint;

later, teams introduce config externalization and split services.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5) Enabling Kubernetes-native operations (rolling updates, probes)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: VM deployments cause downtime; no standard health checks.<\/li>\n<li><strong>Why this service fits<\/strong>: Generated manifests provide a baseline to add readiness\/liveness probes and rollout strategies.<\/li>\n<li><strong>Example<\/strong>: After migration, the team adds <code>\/healthz<\/code> probes and uses Deployment rolling updates.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6) Consolidating multiple VMs into shared GKE clusters<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: VM sprawl increases cost and operational overhead.<\/li>\n<li><strong>Why this service fits<\/strong>: Containers share nodes and can be right-sized via requests\/limits.<\/li>\n<li><strong>Example<\/strong>: 20 lightly used VMs become 20 Deployments across two regional GKE clusters with node pools sized for steady vs burst workloads.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">7) Building a migration factory (waves and playbooks)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: One-off migrations are inconsistent and hard to repeat.<\/li>\n<li><strong>Why this service fits<\/strong>: Creates a repeatable process: assess \u2192 convert \u2192 validate \u2192 deploy \u2192 cutover.<\/li>\n<li><strong>Example<\/strong>: A platform team defines a standard validation checklist and rollout plan for each migrated workload.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">8) Pre-refactor step before moving to Cloud Run or microservices<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: App must be containerized first;

little visibility into vulnerabilities.<\/li>\n<li><strong>Why this service fits<\/strong>: Container images can be scanned, and deployments can be policy-controlled.<\/li>\n<li><strong>Example<\/strong>: After migration, Artifact Registry scanning and admission policies prevent deployment of high-severity vulnerable images.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">10) Hybrid operation during transition (dependencies remain on VMs)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem<\/strong>: App needs a database still on-prem; full migration takes time.<\/li>\n<li><strong>Why this service fits<\/strong>: You can run the app on GKE while keeping connectivity to existing dependencies.<\/li>\n<li><strong>Example<\/strong>: App moves to GKE;

FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1) Is Migrate to Containers the same as \u201cMigrate for Anthos\u201d?<\/h3>\n\n\n\n<p>Migrate to Containers is the current Google Cloud product name commonly associated with what was previously branded as <strong>Migrate for Anthos<\/strong>. Confirm the latest naming and scope in official docs: https:\/\/cloud.google.com\/migrate\/containers\/docs<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2) Does Migrate to Containers migrate my database too?<\/h3>\n\n\n\n<p>Typically, it focuses on <strong>VM-to-container<\/strong> conversion for application workloads. Databases are usually better migrated to managed services (e.g., Cloud SQL) or handled with dedicated database migration tooling. Verify supported scenarios in the docs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3) Does it work for Windows VMs?<\/h3>\n\n\n\n<p>Windows containerization has constraints and support varies by product version. Verify current support matrices in official documentation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4) Can I deploy to Kubernetes other than GKE?<\/h3>\n\n\n\n<p>The artifacts are Kubernetes-based, but the service is designed around Google Cloud workflows and GKE. Portability depends on generated manifests and your target Kubernetes environment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5) Do I need a dedicated GKE cluster for migration processing?<\/h3>\n\n\n\n<p>For production, it\u2019s a common best practice to isolate migration tooling. For labs or small migrations, some teams use a shared cluster\u2014but isolation is safer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6) How \u201cautomatic\u201d is VM-to-container conversion?<\/h3>\n\n\n\n<p>It can automate a significant portion, but most real apps need follow-up work:\n&#8211; configs and secrets externalization\n&#8211; probes and resource tuning\n&#8211; networking\/service discovery adjustments\n&#8211; storage redesign for stateful components<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7) Will the migrated container be optimized?<\/h3>\n\n\n\n<p>Often the first output is functional but not minimal. Plan time to reduce image size, remove unused packages, and adopt best practices.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8) What\u2019s the difference between Migrate to Containers and Migrate to Virtual Machines?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Migrate to Virtual Machines<\/strong>: move VMs with minimal change (lift-and-shift).<\/li>\n<li><strong>Migrate to Containers<\/strong>: convert VM workloads into containers and Kubernetes artifacts (re-platform to Kubernetes).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">9) Can I use this for a \u201cstrangler\u201d migration?<\/h3>\n\n\n\n<p>Yes. You can migrate one component\/service while leaving others on VMs, as long as networking and dependencies are handled carefully.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10) How do I handle secrets after migration?<\/h3>\n\n\n\n<p>Move secrets out of the VM filesystem into:\n&#8211; Secret Manager + CSI driver (common pattern), or\n&#8211; Kubernetes Secrets with tight RBAC and encryption options.\nAvoid embedding secrets in container images.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">11) What networking is required for on-prem VMware sources?<\/h3>\n\n\n\n<p>You generally need:\n&#8211; routable connectivity (VPN\/Interconnect)\n&#8211; firewall openings to required endpoints\/ports\n&#8211; DNS resolution\nExact requirements depend on connector design; verify in official docs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">12) Does it support private GKE clusters?<\/h3>\n\n\n\n<p>Often yes, but private clusters require careful setup for API access and egress (NAT, Private Google Access). Validate the official guidance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">13) How do I estimate migration effort?<\/h3>\n\n\n\n<p>Do an assessment on representative apps and categorize:\n&#8211; easy (stateless)\n&#8211; moderate (some config\/storage changes)\n&#8211; hard (system dependencies, stateful, complex networking)\nUse that to forecast waves and staffing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">14) How do I roll back if the containerized app fails?<\/h3>\n\n\n\n<p>Keep the VM running during initial cutover and switch traffic back via DNS\/load balancer if needed. Plan rollback as part of your runbook.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">15) What\u2019s the biggest reason migrations fail?<\/h3>\n\n\n\n<p>Underestimating:\n&#8211; dependency mapping (DNS, service discovery)\n&#8211; state\/storage redesign\n&#8211; operational readiness for Kubernetes (monitoring, alerts, on-call procedures)<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">17.

Summary<\/h2>\n\n\n\n<p><strong>Migrate to Containers<\/strong> on <strong>Google Cloud<\/strong> is a practical <strong>Migration<\/strong> service for modernizing VM-based applications by converting them into <strong>containers and Kubernetes deployment artifacts<\/strong>, usually targeting <strong>GKE<\/strong>. It matters because it helps teams move faster than full rewrites while still making meaningful progress toward standardized, scalable operations.<\/p>\n\n\n\n<p>From an architecture perspective, plan for a <strong>processing cluster<\/strong>, solid <strong>network connectivity to sources<\/strong>, and a secure artifact supply chain (Artifact Registry + IAM). From a cost perspective, the biggest drivers are usually <strong>GKE cluster runtime<\/strong>, <strong>artifact storage<\/strong>, <strong>load balancers<\/strong>, and <strong>networking<\/strong>\u2014so treat migration infrastructure as ephemeral when possible.
