The document summarizes the implications of upgrading a Blackboard 7.2 server environment to Blackboard 9.0 for system administrators. It describes the upgrade path from 7.2 to 9.0 through several intermediate versions. Extensive preparation was required, including testing different upgrade methods and building custom tools. The upgrade took several system administrators two months of full-time work. It involved restoring databases and applications, going through each step of the upgrade path, and addressing various issues like performance tuning afterwards.
