After you download a patch or a new version or you update the database that you connect to, you are notified that upgrade is necessary when you open a connection used for data mining. The GUI issues a message describing the problem and asks you if it should perform necessary migration. If you answer yes, you are prompted for the administrative (SYS) password.
Migration may require conversion of the Repository as described in XML DB Requirements for Data Miner 4.0. If migration is required, a Repository Migration dialog launches.
