This chapter describes how to upgrade from an earlier release of DB2 OLAP Server or DB2 OLAP Integration Server to Version 8.1, and how to migrate your OLAP applications and databases from one computer to another.
It is recommended that you do a complete, not incremental, backup of all of your DB2 OLAP Server and DB2 OLAP Integration Server files before upgrading. You can then revert to the earlier version if you have problems.
