tek-tools /opt/PRAgent Install on Solaris 10

I'm in the process of upgrading from an older server running Solaris 2.9  to a new Sun sparc M5000 running Solaris 2.10. How do I bring the PRAgent (profiler agent) from the old to the new?  Can I simply copy the directory? Or must I go through a special install or use the unix pkgadd process.  I am currently running: PRODUCT_NAME="Profiler", PRODUCT_VERSION="4.6.4"

Any help at all will be a great assistance.
