Component : CA View
View 14.0 can be reverted to View 12.1 (as well as 12.2).
Here is a link that provides information on the process:
The View systems can be upgraded in stages, as View is downward-compatible regarding the database levels.
The 14.0 code level can be implemented at this time, and the 12.1-level databases will work as expected.
A SARDBASE VERSION 14.0 should eventually be run on the databases, to bring the database levels up to the code level.
