We have controller and EUM hosted on different hosts. We have gone through  the doc https://docs.appdynamics.com/display/PRO45/Upgrade+the+Production+EUM+Server. Under upgrade procedure in second step i.e 2.b we could see we have to take mysql dump from the controller as below. ./mysqldump -u root --password --protocol=TCP -P [Controller-MySQL-Port] --databases eum_db --add-drop-database --socket=<controller_home>/mysql/mysql.sock > eum_db.sql After taking the dump when do we need to place the eum_db.sql in EUM server. In 5.e we  could see below procedure. Import the backed-up MySQL tables to the new database: EUM Server 4.3 ./mysql -u root --password --protocol=TCP -P [EUM-MySQL-Port] --socket=<eum_server_home>/mysql/mysql.sock < <controller_home>/db/bin/eum_db.sql Is this back up which we have taken from the Controller server or any other. Please clarify. Regards, Anuradha. ... View more
