SLES 11 sp 2 in Hyper-V

I need to migrate SLES 11 sp2 in Hyper-V (Win 10) and I would like to know how to setup my virtual machine. Which generation: 1 or 2? VHD or VHDX disks? IDE or SCSI? Something else? SLES 11 is old and i’m afraid that if I choose the newest options in Hyper-V then not everything will work well. For example, IBM writes that SLES 11 sp2 is not friendly with VHDX disks https://www.ibm.com/support/pages/vhd-disks-not-vhdx-must-be-used-when-installing-sles-11-sp2-vm-under-hyper-v-ibm-system-x3690-x5-7147

These are the openSUSE forums, not the SLES/SLED forums. Look at https://community.suse.com/
