During most upgrades, all databases associated with a server are automatically upgraded. Major upgrade, for example, from version 12.5.x to version 15.5, require that you run the preupgrade and upgrade utilities to complete the upgrade.
As a result, database and transaction log dumps created with an earlier version of SAP ASE must be upgraded before they can be used with the current version of SAP ASE.
SAP ASE provides an automatic upgrade mechanism—on a per-database basis—for upgrading a database or transaction log made with Backup Sever to the current SAP ASE version, thus making the dump compatible for use. This mechanism is entirely internal to SAP ASE, and requires no external programs. It provides the flexibility of upgrading individual dumps as needed.
Loading an older version of the master database. That is, if you upgraded SAP ASE to the current version, you cannot load a dump of the master database from which you upgraded.
