:ACTION_CONVERT:
== Name
cryptsetup-convert - converts the device between LUKS1 and LUKS2 format
== SYNOPSIS
*cryptsetup _convert_ --type <format> [<options>] <device>*
== DESCRIPTION
Converts the device between LUKS1 and LUKS2 format (if possible). The
conversion will not be performed if there is an additional LUKS2 feature
or LUKS1 has unsupported header size.
Conversion (both directions) must be performed on inactive device. There
must not be active dm-crypt mapping established for LUKS header
requested for conversion.
The *--type* option is mandatory with the following accepted values: _luks1_ or
_luks2_.
*WARNING:* The _convert_ action can destroy the LUKS header in the case
of a crash during conversion or if a media error occurs. Always create a
header backup before performing this operation!
*<options>* can be [--header, --type, --disable-locks].
