Easy performance monitoring tools in Solaris?

Question

I'm in the middle of a hardware upgrade. The application expert has on our project work list "copy /opt/tomcat/* from old machine to new machine.

The old machine is a Sun V240, running Solaris 9 and the New machine is an Oracle (Sun) T4 server running Solaris 10. Tomcat version is Tomcat 6.

Can we do this? will it run? It seems to be a Java based product and it stands to reason that if the JDK is the same it would be fine. I'm worried about any C code compiled for Solaris 9. Why should we NOT do this ?
