How does the "version" tag works in the Json export of a visualization in Kibana?

Hello,

So these are called migration versions and they get updated from developers when make changes in the code of how they are implemented. Here is our developer documentation on it - Kibana Core API | Kibana Guide [7.12] | Elastic

So this won't impact how you plan to store your import JSON files. You can come up with your name and version for storing in git. Let me know if this helps and if you have more questions.

Thanks,
Bhavya
