Flarcreate and excluding directories with software installed

Got a solaris 10 server that I want to take a flar of in order to use to build a new server. Works fine.

Only trouble is there is software on the original server that is not needed on the new server - it will be uninstalled.

I was thinking of creating the flar from the original server and excluding the install directory (its quite large and I need to ftp the resultant flar to a remote location). I can do this using -I option (otherwise it complains about package database).

If I do this, is it going to work? Or on the resultant system, am I going to get packages installed but no physical directory for the software and problems sorting out the package database?
