Upgrade or revert a DataBlade® module

You can use the SYSBldPrepare( ) function to upgrade a registered DataBlade® module to a higher version, or to revert to a lower version. Like BladeManager, the SYSBldPrepare( ) function does not allow more than one version of the same DataBlade® module to be registered in the same database. When you register the replacement version, you do not need a second call to SYSBldPrepare( ) to unregister a DataBlade® module that you have replaced with another version.

Before you can change the registered version of a DataBlade® module, the other version must be installed in the $INFORMIXDIR/extend directory.
