Preparing a Storage Control File

A key task for a successful upgrade is the building of a suitable storage control file for both the development and production upgrade. You must consider space requirements. This is particularly important for the development upgrade, because three new repositories are imported into the database (one extra repository is imported during the production upgrade). Some repository tables will increase significantly in size, so you must provide sufficient space for expected database growth.

Release 7.7 offered a new database schema structure. For more information, see New Database Schema Structure in Release 7.7.
