Problem Definition

Jira data center currently doesnt support Atlassian Document Format (ADF)
Reference: https://developer.atlassian.com/cloud/jira/platform/apis/document/structure/

Suggested Solution

ADF should be supported in Jira Data Center too.

Usecase:
We have customer who would migrate from the Cloud instance to DC. Any ADF content in cloud wont be rendered in Jira DC, which affects the way users work on the issues they have in their instance.
