changing mount point under VCS

Hi Experts

How can we change the mount point for shared external volume under the veritas cluster online.

specs:

1) OS: Solaris

2) No of nodes in cluster: 10

e,g.

currently we have: /dev/vx/dsk/abcd1dg/vol01  mounted on  /var/opt/ABCD1

We need to make it like:  /dev/vx/dsk/abcd1dg/vol01  mounted on  /var/opt/abcd1

Thanks for your time and help.
