NWDI - New track creation for 7.3

Hi All,

The current SLD details are as follows:

SLD Version : 7.0017.20080813092411.0000

JAVA VM : IBM Corporation 1.4.2 on Linux 2.6.16

Currently, the NWDI is configured and have few Tracks created for different 7.0 webdynpro projects.

I want to create a new track  for  a Webdynpro project which should be developed on NWDS 7.3 and need to be deployed on portal 7.30 WebAS.

Now, I dont want to disturb the existing 7.0 webdynpro projects but parallely want to create a new track for 7.3 webdynpro projects for further developments.

So, can someone provide me some inputs on the same?

Thanks.
