No offense intended, but that you have to ask strongly indicates you should not attempt this migration yourself (unless it's a non-critical or personal system that can be sacrificed at the altar of education).

Aside from moving files, bootloaders may need reinstalling and system files which reference partitions may need updating (e.g. /etc/fstab). The exact procedure is system dependent.

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME
volunroot - Remove Logical Storage Manager hooks for rootable volumes SYNOPSIS
/usr/sbin/volunroot [-a | -A] OPTIONS
Specifies that all volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and swapvol. Forces removal of the private region unless it is the last one in the system. DESCRIPTION
The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk directly through disk partitions instead of through volume devices. The script also removes other changes that were made to enable booting of the system from the root volume, so that the system will boot with no dependency on the Logical Storage Manager. When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol. For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by volrootmir or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions defined for them on the disk. If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions. The unwanted plexes can be removed using either voledit or volplex. SEE ALSO
