If you have management site components installed on multiple computers, ensure that you upgrade components in the correct order. On the computer where you run the setup program, the program ensures that you upgrade components in the correct order. However, when you have components installed on multiple computers, ensure that you upgrade the computers in order. For example, if the QDB and the management server are on different computers, upgrade the QDB before you upgrade the management server. For more information about the correct order for upgrading AppManager components, see Section 1.8, Understanding the Recommended Order for Upgrading Components.
