We are running Blacklabelops/Jira 7.4 and are wanting to upgrade to the New Atlassian Jira 8.3 Docker image. The server also has Nginx and Postgress 9.6.3 Docker images. What is the best way to migrate the data? We are planning on running both images for a short while so we can test our migration and give users a chance to look at the new UI.
This is my first time dealing with Docker and a Jira upgrade. Is there a doc or resource that will help walk me through this process or should I reach out to Atlassian?
Thank you.
