We had an employee walk out and I've taken over his projects. The subscriptions for this expired before we even knew about them. It turns out we need the data and to continue our project, but I don't know which products exactly he had and if the data will still be there.
1) How do I find out which exact products we had?
2) Will the data still be there?
3) What do I need to learn to use the Jira software and Bitbucket (I think these are what he used in the past).
