resolves #121 This app pulls in data from the PCFScheduler, AppSummary, AppManifest, the SCDF Task Definition Schema to construct the new schedule for the migration. You will note that for the App Summary, the code was pulled directly from the CF-Deployer, the reason this was done was to obtain additional schedule information required for the migration, without having to make another call to retrieve the app summary (i.e. obtain this detail while its still there). As discussed in the README, you will see that not all properties could be obtained from the available resources and thus have to be populated by a property that user can establish at runtime. However this also means this affects all schedules to be migrated. Updated to allow user to setup maven repository Updated instructions to include how to execute migration Updated docs Updated to support deployer format for tasks Also updated deployers to current release
