You can change virtual machine hardware, such as CPU, memory, hard disks, disk-level storage policies, and NICs.

The number of virtual CPUs and memory that a virtual machine supports depends on its virtual hardware version.
Table 1. Virtual Hardware Versions and CPU and Memory Support
Virtual Hardware Version Maximum CPUs Maximum Memory
HW4 4 64GB
HW7 8 255GB
HW8 32 1011GB
HW9 64 1011GB
HW10 64 1011GB


If CPU hot add or memory hot add is not enabled for the virtual machine, power off the virtual machine before you change the CPU or memory.

Power off the virtual machine before you change the storage policy for a virtual machine disk.
