  • Auto-discovery of all on-premise resources

🚀 VMware Agent-Based Migration: The Game Changer

Securely migrate VMware VMs to Azure, AWS, or any cloud WITHOUT exposing vCenter to the internet! Our revolutionary agent architecture transforms how enterprises approach virtualization migrations.

💡 Why It's Revolutionary

Traditional cloud migration tools require exposing your vCenter server to the internet or setting up complex site-to-site VPNs. Our agent architecture changes everything. Deploy a lightweight agent inside your VMware environment, and it acts as a secure bridge—you maintain complete control over your infrastructure while we provide cloud orchestration. It's the perfect balance of on-premises security with cloud convenience.

❌ Traditional VMware Migration

  • Must expose vCenter to internet (major security risk)
  • Complex VPN tunnels required for cloud access
  • vCenter credentials sent over internet
  • Requires opening inbound firewall ports
  • Limited to single-site deployments
  • Slow transfers over VPN/internet connection
  • Cannot access air-gapped environments
  • Compliance and security audit nightmares

✓ MigroStack Agent-Based VMware Migration

  • Zero internet exposure - vCenter stays private
  • No VPN required - agent uses outbound HTTPS only
  • Credentials never leave your network
  • Firewall-friendly (outbound connections only)
  • Multi-site support from single agent
  • Full LAN speed access to ESXi hosts
  • Works in completely air-gapped data centers
  • Passes security audits with flying colors

🔒 Security Benefits of Agent-Based Architecture

🛡️

Zero Internet Exposure

vCenter, ESXi hosts, and datastores remain completely isolated from the internet. Agent handles all external communication via encrypted outbound connections.

🔐

Credentials Stay On-Premises

Your vCenter credentials are configured locally on the agent and never transmitted to the cloud. You maintain complete control over authentication.

🚪

Outbound-Only Communication

Agent initiates all connections via WebSocket over HTTPS. No inbound firewall rules, no port forwarding, no security policy changes required.

On-Premises Execution

All VMware operations execute locally at LAN speeds. No data transferred until final upload to cloud destination, ensuring maximum speed and control.

🎯

Direct ESXi Access

Agent can directly access ESXi hosts, datastores, and vSAN storage without routing through external networks. Full visibility and performance.

🌐

Multi-Site Support

Single agent can manage migrations from multiple vCenter instances, data centers, and ESXi clusters. Simplify complex enterprise deployments.

✨ Extra Features Enabled by Agent Architecture

  • Direct datastore access - Read VMs at full SAN/NAS speeds
  • Bypass VPN limitations - No bandwidth throttling or connection limits
  • Access internal networks - Reach isolated management networks
  • Intelligent queueing - Agent handles job scheduling and retry logic
  • Progress tracking - Real-time visibility into migration status
  • Auto-discovery - Find all VMs, hosts, and datastores automatically
  • Network optimization - Compress and deduplicate before transfer
  • Snapshot management - Create pre-migration snapshots for safety

🎯 Real-World Example: Healthcare Provider Migration

A major healthcare provider needed to migrate 500 VMs from their HIPAA-compliant on-premises VMware environment to Azure Government Cloud.

The Challenge: Their security policy prohibited exposing vCenter to the internet, and their existing VPN couldn't handle the bandwidth needed for VM transfers.

The Solution: Deployed a MigroStack agent inside their secure network perimeter. The agent:

  • Connected to vCenter locally (no internet exposure)
  • Accessed VMs directly from internal datastores at 10 Gbps
  • Used outbound HTTPS to communicate with MigroStack orchestration
  • Transferred VMs to Azure Government Cloud over encrypted connection

Result: 500 VM migration completed in 3 weeks instead of 6 months. Zero security policy violations. Zero inbound firewall changes. Full audit trail for compliance.

When You Need Remote Agents

🏢 Large File Share Migrations (100TB+)

Migrating terabytes of data from on-premise file servers to SharePoint or cloud storage requires local access for acceptable speeds.

Example: A 500TB file server migration that would take 8 months over a 100Mbps internet connection completes in 2 weeks with remote agents accessing files at 10Gbps LAN speeds.

🏭 Multi-Site Enterprise Deployments

Organizations with branch offices, data centers, or manufacturing sites need agents at each location to avoid centralizing data traffic.

Example: Deploy one agent per regional office to migrate local file servers without saturating WAN links to headquarters.

🔒 Air-Gapped or Restricted Networks

Highly secure environments that prohibit VPN connections or limit outbound traffic can use agents with controlled connectivity.

Example: Healthcare facilities with HIPAA-compliant networks can migrate PHI data using agents with approved outbound-only connections.

📁 Legacy System Migrations

Older file servers, NAS devices, or proprietary storage systems that can't expose data over modern APIs need local agent access.

Example: Migrate data from a 15-year-old NetApp filer that only supports SMB v1 by deploying an agent that can mount the shares locally.

⏰ Time-Sensitive Migrations

When you have a hard deadline (datacenter closure, vendor contract end), agents provide the speed needed to meet it.

Example: Complete a 50TB migration in 48 hours instead of 6 months to meet a datacenter decommission date.

🌍 Global Migrations with Regional Compliance

Keep data within regional boundaries by deploying agents locally that transfer to region-specific cloud destinations.

Example: EU office data stays in EU Azure regions, US data stays in US regions, all orchestrated from a single MigroStack portal.
