Datababase converion: Unify to Oracle

hi,

I’d like to know the steps and procdures to convert the “unify” database in unix to “oracle”. Is there any tools for this in oracle.

I heard that it is possible to convert it by using XML and PHP(or JSP). But I’m not sure how to do this?

If anybody already have done the same conversion, please post the problems that u faced in the conversion.

If you know any article reference, please let me know the URL.

regards,
