ZENworks Appliance 2020.2 - ESXi to HyperV

Question

Hello all, as many of you have faced, it's time for us to Move away from ESXi and towards hyperV given the issues with Broadcom and licensing. I have migfated ALL of my VMs to HyperV and or Azure, and only My ZEBworks 2020.2 appliance is left, but I am having issues. I have tried migrating the ZENworks 2020.2 appliance with the Starwind convertor (Which can literally migrate ANY vm to any other hypervisor, and has worked with every other machine I have) from ESXi to HyperV. Once migrated the Grub BOOT screen came up and then I am presented with this screen forever: 
 So I thought to myself, maybe something wend wrong with the conversion. So grabbed Acronis True image and imaged both of the ZENworks HDDs (OS and DATA), then build a new VM. and imagied the virtual drives with the acronis backups to the appropriate drvies. The same scenario played out, and I was presented with the same screen above after grub boot. In bot scenarios the migration was successful and all the data seems to be there, can anyone give me any insight as to what possibly needs to be tweeked or any direction so I can get this migration to work? I just don;t see any reason for this, since it isa a clone of the exact drice weather its migration with Starwinds or a clone with Acronis True Image.

I AM VICTORIOUS!!!!!!! I have SUCCEEDED in migrating my Production ZCM 2020.2 appliance FROM ESXi to HyperV. Long story short, I needed to Enable the HyperV modules/Drivers, and rebuild them into intrimFS using dracut. I have attached detailed instructions on how I safely did the migration for anyone else who wants to Migrate from ESXi to HyperV without having to rebuild their PRODUCTION server :) Actually I'll just copy and paste it into here. 
 
 ZENworks and iPrint Appliance - ESXi to HyperV Migration 
 
 NOTE: The Microfocus/OpenTEXT ESXi and HyperV Appliances are ultimately the same images, HOWEVER, if you use the ESXi image and try to migrate it to HyperV, ONLY the ESXi/VMWARE Virtual Disk Drive DRIVERS are available, and OR if you use the HyperV image, of the appliance and try to Migrate it to ESXi, in both scenarios Migrating from one ESXi/VMWARE&rarr;HyperV OR HyperV&rarr;ESXi you will find that once you migrate, your Appliance will NOT boot. 
 
 This is because the Virtual Drive DRIVERS on both platforms are ONLY enabled for the Appliance flavor you chose. So if you choose the ESXi/VMWARE OVA to deploy the appliance, you will ONLY have the ESXi/VMWARE Virtual Drive DRIVERS enabled. The same goes for the HyperV Appliance, .vhdx file, if you deploy that for HyperV, you will ONLY have the HyperV Virtual Drivers Available, so when you migrate, you will not boot. 
 
 Solution: In my Scenario, I want to go from ESXi to HyperV. It turns out the modules are already installed but NOT activated. So we will:

Enable the Hyper-v modules.

Edit /etc/dracut.conf and CREATE a special config file /etc/dracut.conf.d/02-hyperv.conf and enable the drivers in BOTH files (because I actually don&rsquo;t know which conf file activates the drivers, so I loaded the drivers in both)

Rebuild the kernel/intrimFS with dracut, so that the drivers are activated in the Linux Kernel for the appliance.

Pre-requisite: 
 
 Shutdown your PRODUCTION ESXi/VMWARE ZCM 2020.2 Appliance

Use Acronis OR StarWind Migrator to clone or Migrate the machine to Another ESXi Hypervisor. (This is so we are working with a COPY of the VM)

On the new ESXi Instance of the Appliance, make sure the Virtual NIC is NOT connected on PowerOn.

Load YAST2

Change the ip address FROM 10.59.XX.XX to some other free IP address (So we are not interfering with the PRODUCTION server, we can always change it back to the real IP once we have it booting

Once changed, turn off the VM and connect the Virtual NIC

On boot up, you will have internet and LAN connectivity.

Perform the steps below

Install the Hyper-V support modules :

zypper in hyper-v 
 
 (they are already installed, so just move to step 2, I left this in in case you use a version of sles 12.5 or the appliance where they are not enabled.

Enable the Hyper-V support modules:

systemctl enable hv_vss_daemon.service systemctl enable hv_fcopy_daemon.service systemctl enable hv_kvp_daemon.service

Edit /etc/dracut.conf and change the add_drivers line to this:

add_drivers+=&ldquo;hv_vmbus hv_netvsc hv_storvsc&rdquo;

Add a driver load file IN /etc/dracut.conf.d (A directory), to load the HyperV drivers as well, just in case (The appliance seems to load from these files)

cd /etc/dracut.conf.d 
 vi 02-hyperv.conf 
 Hit &ldquo;i&rdquo; fir insert 
 Add the line: add_drivers+=&ldquo;hv_vmbus hv_netvsc hv_storvsc&rdquo; 
 Save the file with :wq 
 Make sure there are NO syntax errors

Run the following command to rebuild initramfs:

dracut -f -v

Now that the drivers are injected, re-migrate or CLONE the machine from ESXi to HyperV VM VIrtual Drives (Starwind or Acronis) 
 I would highly suggest bringing up the Machine on a PRIVATE HyperV network switch so that ONLY another Windows VM on the HyperV server can access your server. 
 The machine should boot now, if it does, as long as it is on the Private HyperV switch, and can only talk to other machines on that Private HyperV switch (LAN access and NO Internet Access), then Change the IP back to the ZCM Appliance original IP in our case it is 10.59.XX.XX 
 Make sure you can ping other devices on the Private Virtual Switch 
 Reboot the ZCM 2020.2 Appliance 
 From the Windows workstation on the same Private HyperV Switch, make sure you can ping the ZCM Appliance at 10.59.XX.XX, if you can, test EVERYTHING now, the web interface, make sure all data is there, make sure its making an LDAP connection, make sure, you can remote machines, make sure you can install and roll out bundles, test MDM functions. 
 If it all looks good, your migration should be complete!!!!! 
 Shut down your Migrated HyperV ZCM 2020.2 Appliance, and change the Virtual NIC to be on your PUBLIC/REAL LAN Virtual HyperV switch. Bring the server back up. You are live now. TEST. Make sure PXE is working live on the network as well as imaging :)
