Doc Text:
When you upgrade from Red Hat OpenStack Platform (RHOSP) 13 DCN to RHOSP 16.1 DCN, it is not possible to migrate from the single stack RHOSP 13 deployment into a multi-stack RHOSP 16.1 deployment. The RHOSP 13 stack continues to be managed as a single stack in the Orchestration service (heat) even after you upgrade to RHOSP 16.1. + After you upgrade to RHOSP 16.1, you can deploy new DCN sites as new stacks. For more information, see the multi-stack documentation for RHOSP 16.1 DCN.

Description James Slagle 2019-05-15 15:04:01 UTC 
Need to document how we plan to support upgrades from 13 single stack to 16 multi-stack.

We plan to support deploying additional stacks to connect to the single stack from an upgraded 13->16 deployment.

We don't support a way to breakup the upgraded single stack, other than parallel migration to new hardware (scale down single stack, deploy additional new stack for the site).
