We have a requirement to migrate VMs to HP DL360 Gen10 from HP BL660 Gen8 & HP BL660 Gen9 clusters.
vCenter & ESXi host version is 6.5
Please let me know if we can perform live migration from Gen8/Gen9 to the Gen10 model servers
Live migration is basically possible if the new host has sufficient resources, and has the same (or more) CPU features as the old one, which is the case here. So yes, that should work.
I use Gen8, Gen9 & Gen10 in my environment. They works absolutely perfectly, I just had to enable EVC.
