6.2.1 Considerations before conversion

Converting a UEFI-based machine

Virtual machines that use Unified Extensible Hardware Interface (UEFI) are currently supported in

VMware ESXi 5 only. If the target virtualization platform is ESXi 5, Acronis Backup & Recovery 11.5

creates a UEFI-based machine. Otherwise, the resulting machine will use the BIOS boot firmware.

Acronis Backup & Recovery 11.5 adjusts the Windows boot mode to the BIOS boot firmware and

ensures that Windows remains bootable.

For Linux operating systems, changing the boot mode from UEFI to BIOS is not supported. When

converting a UEFI-based machine running Linux, make sure that it uses GRUB version 1 and that the

target virtualization platform is ESXi 5. For more details, see "Support for UEFI-based machines" (p.

29).

Logical and dynamic volumes

The resulting machine will have basic volumes, even if Linux logical volume structure is present in the

backup. The same applies to dynamic volumes used in Windows systems. If you want to recreate

logical or dynamic volumes on the machine, perform the conversion as described in “Recovery to a

manually created virtual machine” (p. 142).

Custom loader reactivation

 During conversion, the disk interfaces may be changed as a result of migration to a different

platform or just manually. The software sets the system-disk interface to be the same as the

default interface for the new platform. The default interface is SCSI for VMware and IDE for other

supported platforms. If the system disk interface changes, the name of the boot device also

changes, while the boot loader still uses the old name.

 Conversion of logical volumes to basic ones may also prevent the system from booting up.

For these reasons, if the machine uses a custom boot loader, you might need to configure the loader

to point to the new devices and reactivate it. Configuring GRUB is normally not needed because

Acronis Backup & Recovery 11.5 does this automatically. Should the need arise, use the procedure

described in "How to reactivate GRUB and change its configuration" (p. 123).

For more considerations about physical to virtual machine conversion, see the "Backing up virtual

machines" document.
