Rolling upgrade procedure to apply a fix pack to MPF v6.3.0

We can perform a rolling upgrade to apply a fix pack or an interim fix to an installation of MobileFirst Server v6.3.0 without downtime of the MobileFirst runtime environment. Performing this rolling upgrade ensures that there is no interruption of service for the mobile applications that query the MobileFirst Server .

To perform this rolling upgrade, install the upgraded version of IBM MobileFirst Platform Foundation in a different environment, for example a new cluster in WebSphere Application Server Network Deployment. This environment must be connected to the same databases as the initial IBM Worklight Foundation installation. You must then switch HTTP traffic progressively from the old environment to the new environment.

The procedure for an in-place upgrade, with interruption of service, is documented at Upgrading to MPF v6.3.0.

Important: This procedure applies to a MobileFirst Server installation, including the Administration Services, the MobileFirst Operations Console, and the MobileFirst runtime environment, but does not apply to the Application Center.

The following topics explain what plan for the production environment, and the steps of the rolling upgrade procedure for MPF, installed in one cluster in IBM WebSphere Application Server, with the HTTP traffic routed by an IBM HTTP Server, and web server plug-ins for IBM WebSphere Application Server.
