APOS solution consultants have been working with BI 4.0, SAP BusinessObjects XI, and their many precursors for over 15 years. They've been through many migrations and upgrades. In fact, many of our solutions began their lives as migration support applications.
Some of those solution consultants delivered a standing-room-only presentation on BI 4.0 migration challenges at the 2012 ASUG BusinessObjects User Conference in September, and partially reprised their presentation in an October webinar. (Download or view the recorded webinar on SAP BusinessObjects 4.0 migration challenges.)
We've collected some of their planning and preparation best practices for your convenience on our website.
