Migrating between Free and Pro versions preserves all checklist data automatically (checklist items and templates).

Upgrading or downgrading between Free and Pro versions can be performed an unlimited number of times.

Upgrade the Free version to Pro steps:

Install paid version Issue Checklist Pro in Jira (go to Jira Settings > Apps > Find new apps page and search for Issue Checklist Pro 🏆)
The doubled checklist will be displayed on the issue page as long as both apps are installed (proceed to the next step to fix it).
Uninstall Issue Checklist Free (from Jira Settings > Apps > Manage apps page) - this step is safe as it preserves all checklist data.
If you block issue transitions using "All checklist items are completed" validator, then please update the workflow to use the validator from the newly installed version.
Enjoy! Your checklist items and templates are already there.
