Maintainance of WebSphere Extended deployment server

When applying maintenance to upgrade the level of WebSphere Application Server Extended Deployment and WebSphere Network Deployment it is important that the deployment manager remain inactive until both upgrades are complete because if the deployment manager is active before both upgrades are complete it may detect an incompatible version of WebSphere Application Server Extended Deployment and remove some required resources from the dynamic cluster. Keeping the deployment manager inactive until both Network Deployment and WebSphere Application Server Extended Deployment updates have been completed will insure that this potential problem does not occur.
