Migrating apps to Cloud Foundry Deigo Runtime

Cloud Foundry has been rebased on a new runtime Deigo

You can follow the steps below to migrate your app with least disruption from the existing DEA VMs to the Deigo cells

 (1) Deploy DEAs & Diego Side by Side when deploying the 1.6.x ERT.  
 (2) Set "Use Diego by default instead of DEAs” = true
 (3) Set "cf curl /v2/apps/APP_GUID -d '{"diego": true}' -X PUT “ for pre-exsiting DEA deployed apps
 (4) Test/Trigger app restages onto Diego as time permits

If any of your apps use the VCAP_APP_PORT variable. Please refactor to simply use the PORT env var. 

Please read this Pivotal Technote that provides details on the migration steps
