I am currently planning the migration of an R/3 Enterprise system from Solaris to HP-UX, with concurrent Unicode migration plus upgrade to Oracle 10g (from 9.2). I would like to use Data Pump instead of old-style exp/imp and am particularly interested in running the import simultaneously with the export, which I understand is a feature of Data Pump. This could save days, potentially. The db is about 1.7 tb.
Has anyone done this? I would appreciate any advice, suggestions, or warnings. Thanks.
