Hi Experts, I'm quite new with Oracle database. I have developed a new HR system for my client by using PHP with Oracle 11g. However, my client had their old HR system with running on Solaris with Oracle 7 database. I have to migrate the data from old Oracle 7 database to the new one. I've tried using Oracle SQL Developer running on my Windows 7 notebook to connect to it via network but cannot. Do you have any recommendations on how to connect to Oracle 7, accessing the data and migrate them to Oracle 11g. Thank you very much.
