Use these basic steps to return to Adaptive Server version 12.5.3 or earlier. Further steps are necessary if you have enabled 12.5.4 features. For the Cluster Edition 12.5.3 ESD #6 is preferred.
Overlay the 12.5.3 or earlier binary as you did when installing 12.5.4.
Restart the server with the old 12.5.x binary.
Run the 12.5.x version of installmaster to return stored procedures to their original version.
These are the minimum tasks needed for rollback. Additional steps are described in the rest of the section.
Direct upgrade to the Cluster Edition is only supported
from versions 12.5 to 12.5.3 ESD #6.
