• from \Apache Software Foundation\Tomcat X.x_RSSO_TomcatX\webapps
• to \Apache Software Foundation\Tomcat 8.0_RSSO_Tomcat8\webapps directory.
• or to \Apache Software Foundation\Tomcat 9.0_RSSO_Tomcat9\webapps directory.

4. Also, copy the database driver from your tomcatX/lib directory to tomcat8/lib or tomcat9/lib directory, or from the RSSO Installer "\BMCRemedySSO\Disk1\lib" folder.
