Stop waiting months to leave VMware

OSSEA's live sync technology replicates your entire VMware estate while VMs keep running in production.

When you're ready to cut over, it takes less than 5 minutes of downtime per VM.Full incremental sync. Zero data loss. Complete validation. Risk-free migration.

Near-live migration with less than 5 minutes downtime per VM.

Why OSSEA's VMware Migration is different

Near-live migration

Unlike traditional migrations that require extended downtime windows, OSSEA uses live synchronization to replicate VMs while they're running.

First pass:
Full disk replication (happens in the background). Subsequent passes: Only changed blocks (CBT tracking).
Final sync:
less than 5 minutes of downtime per VM.

Incremental block tracking

UOSSEA tracks changed blocks using VMware's CBT (Changed Block Tracking) API. This means:

  • Only modified data is transferred after the initial sync
  • Minimal bandwidth usage during final cutover
  • Predictable migration windows
  • Continuous sync until you're ready to switch

Zero data loss

OSSEA's migration engine ensures 100% data integrity:

  • Automatic checksum verification
  • Point-in-time consistency
  • Rollback capability if needed
  • Complete audit trail

Migration process

1. Discovery & Assessment

OSSEA scans your VMware environment and catalogs:

  • VM inventory (CPU, RAM, disk, network)
  • Dependency mapping
  • Storage utilization
  • Resource requirements on OSSEA
  • Generate a detailed migration plan with timeline estimates.

2. Initial Replication

Full disk sync happens while VMs stay online:

  • Parallel VM migrations (concurrent transfers)
  • Encrypted data transfer
  • Automatic bandwidth throttling
  • Progress tracking in real-time
  • This phase can run for days/weeks in the background.

3. Incremental Sync

Continuous replication of changed blocks:

  • CBT-based change tracking
  • Near-zero performance impact
  • Sync as often as needed
  • Target VMs stay ready for failover
  • Run incremental syncs until delta is minimal.

4. Validation & Testing

Test VMs on OSSEA before cutover:

  • Non-disruptive test failover
  • Application compatibility checks
  • Performance validation
  • Network connectivity tests
  • Validate everything without affecting production.

4. Validation & Testing

Test VMs on OSSEA before cutover:

  • Non-disruptive test failover
  • Application compatibility checks
  • Performance validation
  • Network connectivity tests
  • Validate everything without affecting production.

6. Post-Migration Optimization

Ensure optimal performance on OSSEA:

  • VM guest tools installation
  • Storage tier optimization
  • Backup policy configuration
  • Performance tuning
  • OSSEA optimizes VMs for the new platform automatically.

OSSEA's migration engine is built for enterprise scale

Concurrent Migrations
Migrate dozens of VMs simultaneously
Bandwidth Optimization
Intelligent throttling prevents network saturation
Deduplication
Skip redundant data across VMs with identical blocks
Compression
Reduce transfer sizes by up to 50%
Resume Capability
Automatically recover from network interruptions

Migration strategies

OSSEA supports multiple migration approaches to fit your business needs

Phased Migration
(Workload Tiers)

Move workloads in stages by priority or criticality

  • Dev/test environments first
  • Non-critical production next
  • Mission-critical workloads last

Hybrid Mode
(Long-Term Coexistence)

Run OSSEA alongside VMware indefinitely

  • New workloads on OSSEA
  • Legacy workloads stay on VMware
  • Gradual migration over time

Lift-and-Shift
(Full Estate)

Migrate your entire VMware environment in a coordinated cutover

  • End-of-contract scenarios
  • Complete VMware exits
  • License renewal deadlines

Real-world example

A 500-VM VMware estate with 150TB of data can complete initial replication in 2-3 weeks (background sync). Final cutover per VM: less than 5 minutes.

What gets migrated?

M hardware specs
CPU, RAM, controllers
Network configurations
VLANs, IP settings
VM metadata
names, tags, annotations
Boot firmware settings
BIOS/UEFI
Guest OS compatibility
Windows, Linux, BSD

What About Applications?

OSSEA uses hypervisor-level replication, which means

No agent installation
Apps don't know they're being migrated
No application downtime
Until final cutover
No reconfiguration needed
Applications run identically on OSSEA
Database-friendly
Works with SQL Server, Oracle, PostgreSQL, MySQL, etc.

Post-Migration Support

OSSEA doesn't just migrate—it helps you stay migrated

Guest Tools
Optimized drivers for performance and manageability
Integrated Backup
Automatic backup policy configuration post-migration
Performance Monitoring
Real-time visibility into migrated workloads
Rollback Capability
Keep VMware source VMs intact until you're 100% confident
