Procedure

You upgrade the software and one or more databases using this software with the help of the SDBINST or SDBUPD program. Which of these two programs applies, depends on the number of databases using the same software installation.

If a software installation is used by just one database which needs to be upgraded together with the software, use the SDBUPD program. It is quick and safe and requires very few user interaction.

(See: Upgrade if an Indidual Database Uses the Software Installation

If a software installation is used by several databases and you want to upgrade one or more of these databases, use the SDBINST program. Within the upgrade process, first install the new version of the database software and then upgrade the required databases one by one.

(See: Upgrade if Several Databases Use the Software Installation)

Starting with version 7.7, the catalog data of all SAP MaxDB databases is stored in Unicode. Therefore, databases of versions up to and including 7.6., the catalog data of which is not stored in Unicode, need to be migrated before you can upgrade them to version 7.7.

The migration procedure must be carried out in version 7.6.

If you want to upgrade a database from version 7.5. or 7.6 to version 7.7 , the catalog data of which is not stored in Unicode, the following procedure applies:

If you want to upgrade a database to version 7.7 , the catalog data of which is stored in Unicode yet, you can directly upgrade your database software to version 7.7.
