Boot mode

Focus mode
Boot mode - Application Migration Service

Choose the boot mode for the test or cutover instance.

You can either choose the Legacy BIOS, UEFI or Use source boot mode. By default, the boot mode is set to Use source boot mode. When this option is selected, MGN will launch the test or cutover instance using the same boot mode as the source server.

Note: When the BIOS option is chosen, AWS MGN converts any non-BIOS instance type to BIOS. As such, the server will be limited to four partitions that cannot equal more than 2TiB due to BIOS limitations.

Note

You must choose the UEFI boot mode for any BYOL source server that is UEFI, as AWS MGN is unable to convert BYOL source servers that boot in UEFI to BIOS.

Note

UEFI boot is only available for Nitro instances.

All Nitro based instance types can also run on UEFI instead of Legacy BIOS.

UEFI is not supported in CentOS 6 and Rhel 6.

Refer to this page for a list of supported instance types.
