Follow these instructions if you are upgrading from an Adaptive Server version 15.0.x to Adaptive Version 15.5.
Adaptive Server restores error messages back to the 15.0.x release from which you are upgrading. Before installing the new messages for 15.5 you must run uninstmsgs.ebf to safeguard the modified messages in your master device.
If you are upgrading from a pre 15.x release, then ignore this step to produce the restore_msgs.ebf file and proceed to run the instmsgs.ebf file.
