AutoConvert Utility
The first time an existing Version 9 database (a database created prior to Progress Version 9.1) is opened for write access, an AutoConvert utility automatically updates the metaschema to support SQL-92 features. The AutoConvert process occurs only once. When it does, the following messages are displayed in the log file:
No further action is required.
AutoConvert cannot be executed within a transaction. In order to successfully complete AutoConvert, you must make a direct connection — single-user and not read only — or start a server. If a transaction has already begun when AutoConvert is invoked, the utility detects that transaction, displays an error message, and aborts the session. AutoConvert aborts the session because the database would be in an unsafe state if the outer transaction aborted after another transaction was completed relying on information associated with the upgrade.
NOTE: Once the AutoConvert utility has run, you cannot revert to your previous metaschema. To retain a copy of your pre-AutoConverted metaschema, back up your existing database prior to opening it for write access with Progress Version 9.1.
