Migration to new server from Window 2003 to 2008

We are in the process of hardware refresh.  On the old server netbackup 7.5.0.6 was installed to D:\Program files\veritas\netbackup but on the new server we are planning to install netbackup 7.5.0.6 to C:\Program files\veritas\netbackup.  Is it a must to install to the same path as the old one?   This is my first time doing this.  We are keeping the tape library (IBM System Storage TS3100), we are just replacing the master server on 2003 machine.  Please help me...........Need to know the implication of installing netbackup to different location on the new serve and how to get this done if it is possible Or what option do I have? 

Please help.

Thanks!
