Moving Disk Suite devices from one controller to another

Hi all,

Background:
===========
We have a E220R installed with Solaris 8. Since we rushed to get the system
going, we connected a Sun S1 Disk array to the external SCSI connection. We
used Disk Suite to mirror the two external drives on the S1.

During the whole process, we figure out the 220R has a single ended Ultra
SCSI interface. On the other end, the S1 has an interface that could go up
to SCSI3 LVD.

To take advantage of the full bus speed, we decided to get a SCSI3 LVD card
for the machine. We brought an Antares PCI card (BTW, only $7xx compares to
Sun's $15xx, and it is certified by SUN).

Questions:
===========
Disks managed by metadevice are c1t0d0 and c1t1d0. If I put the SCSI
adaptor in the system, the disks will become c2t0d0 and c2t1d0. How can I
update Disk Suite reference nicely with breaking any software installed on
the external drives?

Thanks
William
