I'm new to Jira, and have the basic installation working. I'd like to import our existing cases from Trac, to Jira. I've read the page about 'Importing Data from Trac', and I'm assuming that this won't run perfectly the first time.
I've created a new project for the old Trac cases. If I run the importer, and I need to make some changes can I simply delete the project, which would roll back Jira to the state it was in before the import? What is the best way to handle the development phase of importing from Trac to Jira?
