I actually did something similar with my team a few months ago. We exported all our confluence articles and all our Jira tasks into Obsidian and then made a few simple extensions to replace the functionality we needed from them (sharing links to pages, ability to make comments on pages, creating new tasks, using bases as a way to organize our todo tasks, use git for file history), for a DevOps team of 4 it has gone very well and it has made an massive improvement for giving our AI agents up to date docs on whatever we're working on.
