# To-do:
|
|
||||||
# - Add ability to choose between local-lvm and local-zfs
|
|
||||||
# - Find way to carry over MAC
|
|
||||||
# - Attempt to find way to fix networking post-migration automatically
|
|
||||||
# - Get script to pull specs of ESXi VM and use them when creating Proxmox VM
|
|
||||||
# - Omit creation of EFI disk upon confirmation of non-EFI BIOS
|
|
||||||
|
|
||||||
### PREREQUISITES ###
