i have restored a VM server 2016 was backed up from hyper v to vmware. during the boot it shows blue screen
the error shows inaccessible boot device vmware server 2016

How did you back it up and move it over to vSphere Hypervisor?

Which did you use? Seems like you restored the os disk without boot partition. 
If you are performing inside os I would recommend VMware Standalone Converter.

@scott28tt i have used VEEAM backup and replication to backup the hyeper v VM.

i have restore it using this tutorial.

have i missed something ?

@stadi13 thank you for your answer, i used VEEAM instead of the converter.

If you used veeam. Try it with Veeam Instant VM recovery instead. It shows you if the VM boots up without restoring it. If it succeed you can migrate it with vMotion into production.

Have you deleted the VM on ESX host and retried the operation?

I strongly recommend a Instant VM recovery to VMware instead of cold restore. Then you can see immediatelly if the VM boots up or not. If successfull you can migrate the VM afterwards to production datastore.

Thank you for your answer

i am doing the instant recovery, the VM doesnt boot up before the migration start.

during the first boots up it errors out with the inaccessible boot device

see screenshot.

Ok - then something with the backup is wrong. When you do the same on the existing hyper-v (no override, without network) does it boot there?

i appreciare your answers.

 

when i try do a instant recovery to the hyper v it seems it will delete the original VM before.

somehow it works different than vMware.

 

but i went ahead and it runs on hyper v. so somehow vMware doesnt like the hyper V VM.

@Centosuser : appreciation is done with kudos here at the community 😉✌🏽

To avoid destroying the existing hyper-v vm you must select the option „Restore to a new location, or with different settings“. So you can set a new name, specify the target pool and network settings.

kudos has been added :). i didnt know sorry

i noticed i can restore other VM, only this RDS server is crashing without any reason.

just to confirm i can restore other VMS, i don't know why this one is not working.

Thank you! Good to hear taht other vms are working. I‘m quite sure taht this is an issue only for this vm. We need to check as next step if the VM boots when restored on hyper-v then we need to fix the vm and it is not a veeam related issue.

did you try the instant vm recovery on hyper-v with the diffrent location option?

i really appreciate your involvement in this.

i am going to deploy a new RDS server on the ESXI, the one we have seems a very bad one.

most of the users are using Folder redirections which makes things easy.

i was happy the file and DC servers were able to migrate.

No problem. Thats VMware community 😉

i think redeployment from scratch is a good solution.


One last question: can you confirm when you reboot the RDS on Hyper-V it boots successfull?

Ok, good to know, that it works on Hyper-V. Did you retry the migration from Hyper-V to VMware? During the Instant VM Recovery - Veeam is performing a conversion into the the VMware format. Maybe something went wrong there.
