It would be very useful to be able to export and then import Topic along with Conversation configuration from one bot to another, so that I would be able to migrate built solution from sandbox to customer environment or another environment.
Export and import bots: https://docs.microsoft.com/en-us/power-virtual-agents/authoring-export-import-bots
For April 2020, we plan to support export/import bots using solutions. See the release notes below.
Idea completed, @chass !
