You are now ready to reinstall your JobServer(s) on the relevant systems as described in Talend Installation Guide.
Please note that Talend JobServer is not compatible with Talend Studio versions prior to 6.0.
Please note that this reinstallation is NOT mandatory and depends on the compatibility between the Talend Administration Center application and the existing JobServer. For a detailed list of compatibilities between these two applications, see Talend Installation Guide.
Upon reinstalling, it is recommended to create a new directory and thus to use a new path for your JobServer(s).
