This is a screen shot of the DBUA Welcome screen.
At the top of the screen are the following two paragraphs:
DBUA interactively steps you through upgrading your database to Oracle Database 11g Release 1 (11.1).
It can be used to perform major release upgrades from previous versions (Oracle9i Release 2 (9.2), Oracle Database 10g Release 1 (10.1), and Oracle Database 10g Release 2 (10.2)) as well as apply new patchsets. Additionally, DBUA can be used to upgrade databases created using any edition of the Oracle Database software, including Express Edition (XE) databases.
Below the text is a Do not display this page again option.
Below the option are Cancel, Help, Back, and Next buttons. The Back button is grayed out, because this is the first DBUA screen.
