Because of the contraint on the avaiable resources, I won't be able to install different versions of Oracle on differnent servers while I do need to test my script against all target versions (8.0, 8.1.5, 8.1.6, 8.1.7 and possibly 9i).
So can I install different versions of Oracle on the same server? If yes, how can I do it? I wonder if Oracle Universal installer going to find something from the registry and prevent me to do that.
FYI -- I am using WinNT and Win2K.
Also, if I've created a database in 8.1.7 and put a lot of data inside, can I migrate them to other versions for testing so I don't have to put in the data again?
I think as long as you are using separate ORACLE_HOME for each version, you should be able to install it on the same server. If this is your Production server, then you should try it on a test server first.
