Thanks for the reply. Linear looks pretty slick, I'll probably give it a try with the Jira Link, and get some experience with it without having to do a whole conversion plus get buyin from the rest of the team. We weren't impacted by the Atlassian outage, but Linear does seem to have a pretty compelling feature-set.
You're right we need add a page in the docs. It was only mentioned in few pages in passing. For now I added a section here until we can make a full page about it: https://linear.app/docs/workspaces#export-workspace-data
