ESXI to Hyper-V
- 
 Have any of you made the transition? I'm about to give it a shot and wanted to know if anyone had any advice or knew what caveats to avoid? https://www.microsoft.com/en-gb/download/details.aspx?id=42497 looks promising.

 We moved from VMware ESXi to a mixture of Azure and XenServer internally. We would have a lot on HyperV if we were running production in house but these days that all gets hosted.

 @GregoryHall has done quite a few conversions.

I was going to use that to convert a client back in March, but when I was on site doing some prep work, I found myself in a DR scenario due to a misconfigured RAID array. I ended up doing a Backup/restore with Windows Server Backup.

 so using backup it converted the VMs?

 @hubtechagain said: so using backup it converted the VMs? Well, It made a normal Windows backup image to a NAS. Then I booted a new Hyper-V VM to the original Server 2008 media and went through the recovery process. That process is designed to handle installing to different hardware in the first place.

 In my home environment I made the switch First because I've always used ESXI I wanted to learn/try something new. Gotta say, huge fan.

 I'm a long-time VMware guy here too... Hyper-V vs VMware would be a tough argument for me. VDI just seems much easier in Hyper-V than VMware... But for straight up server virtualization, to me, Hyper-V wins on pricing.

 Just to put it into the conversation here, Microsoft has a tool to convert your ESXi VM's to Hyper-V. https://technet.microsoft.com/en-us/library/Gg610672.aspx Now I haven't used it, but it's at least looking into if you must V2V your VM's.
