RHV migration to vSphere

[GabrieleB]

Hello,

in the next months we are going to migrate our RHV environment to vSphere, probably the 6.7 version. I found that Vmware converter standalone should support KVM based environments and all of our CentOS/RHEL virtual machines. We have also a few physical Rhel servers that are probably going to be migrated to vm.

Did anybody have experience with this operation? Do you have any hints or issues that we should consider before starting to move our servers?

Our Rhev-m version is 4.2.8.9

Our hypervisors version is 4.3.5

Please let me know if you need further informations

Thanks in advance

The only way I can think of is to do migration with the export ovf template process.

I suppose you want to migrate the VMs, not the hypervisors and management.

When Converter is in P2V mode (converting powered on machines, and it can't convert powered off KVM machiines), it basically treats them like physical ones. What matters are VMs OSes distros and versions. Check them in Converter user guide or release notes.

There have been various quirks related to Linux P2V, unrelated to KVM. You may want to read the release notes and acquaint yourself with them. If your environment contains e.g. a few sets of machines (grouped by distro/version), it would be a good idea to test-convert at least one from each group to see whether everything works smoothly.

HTH,

GabrieleB,

Question. We are getting ready to perform the same migration task.  What did you end up doing? What was the success rate? Did you run into any issues? Do/Did any of your RHEL/CentOS VMs have LUKS on them?

I'm trying to get an idea of what obstacles we might run into before we start, so any advice or recommendations you have would be greatly appreciated.
