Moving Mediaserver from one Master to another

Hi All,

This is my current setup

Site A

One Master Server (MASTER A) + 2 Media Server (Site A Media + Site B Media)

Site B

This site has no Master server so I'm building new Master here which will me MASTER B.

Requirement

Since Site B Media is already physically located in SITE B I want to move it under the control of MASTER B , right now its controlled by MASTER A

All of the enviorment is on Solaris 10. with NetBackup 7.5.4

My question is do I have to do nbdecommion + uninstall + reinstall or can I do nbdecommision + modify bp.conf and vm.conf.

The reason I do not want to do uninstall and resinstall is I do not want to reconfigure OST and Tape Libraries.

Please let me what all you think.
