Upgrade 3.02 to 3.06 Question

I’d like to upgrade my RT from version 3.02 to 3.06. From what I’ve read in
the instructions, it sounds as easy as:

FOR UPGRADING: (Within the RT 3.0.x series)

As root, type:

            make upgrade     (replace "make" with the local name for

Make, if you need to)

This will build new binaries, config files and libraries without overwriting
your RT database.

It may then instruct you to update your RT system database objects.

Are there any other watchouts? Is there anything else I need to be thinking
about before I run the upgrade script?
