Introduction:
What is the recommended method if we need to back out a maintenance build with Web Viewer 12.1?
Instructions:
We recommend using the backup that is made during the maintenance install. You are prompted on whether to backup when installing a maintenance build.

Backups are by default stored in 
....../CA_OM_Web_Viewer/backups   (.....\CA_OM_Web_Viewer\backups )

The backup directory contains the two Web Viewer .war files that can be deployed with the Tomcat manager. 

A more important question is what you they are using for a database. If you are using internal Derby, you need to backup: 
..../CA_OM_Web_Viewer/apache-tomcat-8.5.24/webapps/CAOMWebViewer12/database/AdminDB 
or
....\CA_OM_Web_Viewer\apache-tomcat-8.5.24\webapps\CAOMWebViewer12\database\AdminDB 

as well. 
If you are using an external database, you don't have to worry about the database.
