Difficulty: EasyHybrid and VMware Cloud on AWS Migrations

A company is planning to migrate a collection of 50 non-production virtual machines (VMs) from their on-premises VMware vSphere environment to VMware Cloud on AWS. The company has scheduled a 4-hour maintenance window for the final cutover, which allows for a brief service reboot. The total data volume is 10 TB, and the migration must be completed with minimal manual intervention. Which VMware HCX migration method should the solutions architect select to meet these requirements?

  1. VMware HCX Bulk MigrationAnswer
  2. B
    VMware HCX Cold Migration
  3. C
    VMware HCX vMotion
  4. D
    AWS Application Migration Service (MGN)

Answer

VMware HCX Bulk Migration is the correct method because it replicates VM data in the background and schedules a switchover with a brief reboot, which meets the downtime tolerance and handles bulk migrations efficiently.
The correct migration method is VMware HCX Bulk Migration because it performs low-downtime replication of virtual machines in the background while they are running. It then schedules a cutover that initiates a brief VM reboot on the destination site, which perfectly aligns with the requirement to migrate 50 VMs with a tolerated brief service reboot during the maintenance window.

Step-by-Step Solution

1
Determine the target platform, number of VMs, data volume, and downtime allowance.
The target is VMware Cloud on AWS, with 50 VMs, 10 TB total data, and a brief reboot is allowed during a 4-hour maintenance window.
Establishes the core requirements to eliminate incompatible migration methods.
2
Compare the VMware HCX migration options against the requirements.
HCX Bulk Migration allows background replication, avoiding long offline times for 10 TB, and supports a reboot-based switchover. Cold migration requires VMs to be offline during the entire transfer (which would exceed the window), and vMotion is for sequential live migrations.
Identifies the option that meets the RTO/RPO requirements and bulk migration capability.
3
Verify if a native VMware tool or an AWS migration service is required.
Since the target is VMware Cloud on AWS, native VMware HCX integration is standard, whereas AWS Application Migration Service targets native Amazon EC2.
Ensures the chosen tool aligns with the target environment architecture.
