making my way into the StarWind ecosystem

[bspeers.dlc]

Hi everyone,

Longtime infrastructure engineer here finally making my way into the StarWind ecosystem after spending years deep in VMware, Hyper-V, storage, networking, and disaster recovery architectures.

I’ve recently been building out a fairly serious migration and interoperability lab to test VMware ↔ Hyper-V workflows, live conversion scenarios, synchronization behavior, storage performance, and cross-hypervisor operational patterns. Current lab setup includes multiple ESXi and Hyper-V hosts, 10 Gb networking throughout, enterprise server hardware, mixed storage backends, and enough blinking lights to mildly concern the local power company.

What originally pulled me toward StarWind was the V2V Converter. I honestly expected “simple free conversion utility” territory, but after seeing the newer synchronization and hot migration capabilities, I became very interested in understanding what’s happening under the hood and where the platform is headed.

I’m especially interested in:

* VMware → Hyper-V live migration workflows
* synchronization behavior and delta handling
* snapshot orchestration
* storage throughput tuning
* cutover strategies
* migration optimization over 10 Gb fabrics
* operational edge cases in production-style environments

I’m hoping to learn from the community and possibly contribute back some findings and documentation of my own as I continue testing.

I’ll probably be posting:

* migration benchmarks
* throughput observations
* workflow diagrams
* synchronization behavior findings
* tuning recommendations
* “things that exploded so others don’t have to” type notes

Very much looking forward to collaborating with everyone here and learning more about how StarWind approaches cross-platform mobility and migration engineering.

Thanks in advance — and thank you to the StarWind team for making tools like this accessible to the community. Free tools that actually solve real infrastructure problems are becoming increasingly rare in this industry.

Welcome to StarWind Forum.
Synchronization stage is where the destination VM catches up with the source. When conversion starts, the snapshot is created and tracks the data changes during conversion. This snapshot merges during the replication phase, so the source and destination both end up with the same data.
Don't be to excited about this stage though. The destination VM is not powered up, and the source is shut down. This means that the feature is there, but it is quite risky because the moment conversion is over, the data gap starts. We plan to mitigate this drawback down the road.

I will gladly read more about the course of the project. Please keep me posted.

Good luck with your project.

Hi Yaroslav, Is this the correct workflow for my scenario?

StarWind V2V Live Migration Workflow (VMware → Hyper-V)

1. Verify source VM health and remove old snapshots
2. In StarWind V2V and connect and start the conversion
3. Select the running (VMware) VM and choose Hyper-V as destination
• StarWind creates a snapshot
• Initial disk copy begins while VM stays online
4. Monitor synchronization and migration progress
5. Test boot VM on Target host.
6. Schedule cutover window
7. Remove VMWare tools and gracefully shut down source VM
8. ReRun StarWind V2V jsut as before for synchronization pass and boot VM on Hyper-V
9. Power up and validate VM on new host.

6 should be done shortly after the conversion.

VMware tools need to be removed before the conversion. This step is optional, but if you find a way to remove it from the destination VM, give it a shot!

The sync window does not seem to appear consistantantly for me.

I saw it during one of my test runs but am not able to get it to appear now.

Hi,

Thanks for your update!
VMware tools removal might be needed only if the VM fails to boot.

OK - how do I ensure the sync page appears?

[yaroslav (staff)]

It is not a separate page or window. It is showing in the conversion log (i.e., the very last step). Once the conversion runs its course, the target VM needs to be shut down.
