What is New?

Let’s get right into it.

Migration Retry

While we love to see green dominate the migration screens, sometimes these operations need to be cancelled “oops – began this migration too soon” or you maybe you are hit with environmental curve balls “oops the target datastore became full.. oops the network” or maybe the operation went sideways and failed.

Retry is a simple but very handy addition to HCX. It gives a vehicle to expedite returning to a migrating state. When you migrate a workload you’re making a good dozen+ choices like on how to migrate and which options to apply.

A retry fast-tracks the experience when you are resuming using the previous selections. When configurations need to change, you can set HCX Enterprise mobility groups back into a draft state for adjustments.

HCX for IPv6 Workloads

This is the beginning of the IPv6 workload mobility journey. In this initial phase, we’ve certified the migration component. The target is dual-stack infrastructure managing IPv6 virtual machines.

With HCX 4.6 you can use the following migration technologies for IPv6 workloads:

  • Replication Assisted vMotion (Mass live migration)
  • HCX Bulk Migration (Mass warm migration with vm customization and post-scripts)
  • HCX vMotion (High compatibility serial live migration, proxied vMotion)
  • HCX Cold Migration (Powered off virtual machines)

Migrated IPv6 virtual machines can use existing IPv4 HCX network extensions (those can even be converted to use IPv6 gateways.

In future HCX releases we will tackle in IPv6 Network Extension, Mobility Optimized Networking, OSAM and everything needed to deploy HCX in fully IPv6 infra.

HCX for NSX 4.1.0

VMware NSX 4.1 released today! 🥳 (Feb 28, 2022).

✔️ HCX 4.6 is fully compatible with the NSX 4.1.0 release.

P.S. We implemented no-device days and now the house becomes a nerf war zone.
