Understanding the HCX
Migration Options

VR/HBR for Efficient and Compatible
Moves.
• vSphere 5+ / VM Hardware v7+
• AMD to Intel.
Parallel: Mass migration with Scheduled
Low Downtime switchover.
Highly Resilient: Transfer halts/resumes on
network path disruptions.
VM Transformation during switchover.
(Disk Type, Tools, HW, Pre/Post Scripts)
Highly Compatible HCX vMotion
• vSphere 5.5 - 7, Hardware v9+,
• vMotion without EVC requirements.
• Works with isolated & overlapping vMotion
subnets.
Serial Operations: Single VM migration with
Live Switchover.
No Virtual Machine changes during the live
switchover.
Ideal for DR avoidance & cloud bursting.

HCX vMotion Capabilities
Seamlessly Migrate VMs Across Infrastructure Boundaries
• Encrypted vMotion between legacy source and SDDC target
• Bi-directional, (Cross-CPU family compatibility without cluster EVC )
• Compatible from vSphere 5.5+ environments (VM HW v9)
• In-flight Optimization (Deduplication / Compression)
• Supports overlapping vMotion vmkernel subnets.
• Serial migration – Protocol tendency to saturate.
• Requires 150ms RTT Latency (HCX supports 250ms with WAN OPT)
• vSphere 6+ required (HCX: Supports 5.5+)
• Does not support encryption (HCX: Inflight encryption)
• Requires routed vMotion networks (HCX vMotion Proxy doesn’t require
the vMotion SRC/DST vmkernel networks to be aware of each other)
• Does not support 3rd party switches (HCX supports N1kv Migrations)

HCX Bulk Migration Capabilities
Low Downtime, Highly Compatible, Resilient to Network Path Degradation
• Encrypted Replication migration between legacy source and SDDC target
• Bi-directional, (Cross-Vendor CPU compatibility, e.g. AMD to INTEL)
• Compatible from vSphere 5+ , VM HW version 7+
• WAN Optimized (Deduplication / Compression)
• Optimized for parallel migration – single replications will not saturate the
link. Build migration waves.
• No line in the sand latency requirements (Latency will influence migration )
• Supports RDMv migrations.
• Supports Virtual Machine transformation as part of the migration workflow.
Tools and VM Hardware can be upgraded to the latest at the target.
• Supports Pre/Post Customization scripts.
• Last resort access hostname/re-IP for corner cases where low downtime is
not a strong requirements.

OS Assisted Replication-
based migration with
WAN Acceleration
Active Replicating
• Utilizes OS assisted replication to migrate
(conceptually similar to vSphere replication)
• Source VM remains online during replication
• Quiesce the source VM for final sync before
migration
• Perform software stack adaptation (fixup)
• Source VM is powered off and the migrated
VM is powered on in target site, for low
downtime switchover
• VMware tools is installed on the migrated VM

HCX Network Profiles
§ HCX deployments will use all configured Network Profiles in the Compute Profile
§ An IP range should be set aside for HCX in each of the Network Profiles.
§ HCX will only use 1 IP address per network profiles.
§ HCX appliance deployments will fail if any of the Network Profiles are exhausted.
§ Individual Network Profiles can be used in many Compute Profiles.
