During most upgrades, all databases associated with a server are automatically upgraded (major upgrades—say 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 Adaptive Server must be upgraded before they can be used with the current version of Adaptive Server.
Adaptive Server provides an automatic upgrade mechanism—on a per-database basis—for upgrading a database or transaction log made with Backup Sever to the current Adaptive Server version, thus making the dump compatible for use. This mechanism is entirely internal to Adaptive Server, and requires no external programs. It provides the flexibility of upgrading individual dumps as needed.
However, these tasks are not supported by the automatic upgrade functionality:
Loading an older version of the master database. That is, if you upgraded Adaptive Server to the current version, you cannot load a dump of the master database from which you upgraded.
Installing new or modified stored procedures. Continue to use installmaster.
