Ok, you have something of a messy situation to deal with here.

And just a couple of comments:
1. If you have any other diskgroups, condier using them instead.
2. If you only have 2 disk why use veritas? Encapsulated roots are a pain SVM is a whole lot simpler for boot disks.

I generally don't like to use vxdiskadm, so I'm not
sure what options you've got there.

The basics:

for each plex on the mirror:
Code:
vxplex -g bootdg -o rm dis <plex>

then
Code:
vxdg -g bootdg rmdisk <mirror_disk_name>
/etc/vx/bin/vxdiskunsetup <mirror_disk_media_name>

remove mirror disk, and replace.
Code:
devfsadm -Cv
vxdctl int
vxdctl enable

layout the new partitions on disk
Code:
/etc/vx/bin/vxdisksetup -i c0t1d0 format=sliced
vxdg -g bootdg adddisk rootmirror=c0t1d0 
/etc/vx/bin/vxrootmir rootmirror

for each other volume
Code:
vxassist -g bootdg mirror <volname>

repeat the procedure for rootdisk, no need to unencapsulate.

vxbootsetup

vxbootsetup(1M) 														   vxbootsetup(1M)

NAME

       vxbootsetup - set up system boot information on a Veritas Volume Manager disk

SYNOPSIS

       /etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]

DESCRIPTION

       The  vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
       disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk.  All of these volumes must
       be contiguous with only one subdisk.

       The -g option may be used to specify the boot disk group.

       If  no  medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
       be bootable.

       If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.

       vxbootsetup requires that:

       o    The root volume must be named rootvol and must have a usage type of root.

       o    The swap volume must be named swapvol and must have a usage type of swap.

       o    The volumes containing /usr and /var (if any) must be named usr and var, respectively.

       See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on  how  the
       system boots and how VxVM impacts the system boot process.  The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
       If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to  make  the
       disk bootable.

ARGUMENTS

       medianame
	    Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
