Greetings, One of our applications has been built on RHEL4 using Oracle 10.2.0.3.0 Standard Edition. The owner of this application is interested in the possibility up upgrading this to Enterprise Edition (I'll forgo the details of the needs). I have found the documentation explaining how to do this and have explained it requires a reinstallation of Oracle. The user has the idea that there is no difference between the installation of standard and enterprise edition of Oracle and one merely needs to throw a couple of switches to make the change. Can someone tell me how to prove that it isn't that simple. What hard evidence can I use to show that a reinstallation is required? Of course if it is that simple I suppose that would be nice too. Licensing and other concerns are not at issue here, this is merely a technical question. Thanks.
