The high effort to switch from TestRail to another tool like Qase is currently one of the biggest obstacles for us and certainly also for other TestRail customers.
Admittedly, TestRail does not make it easy for its (former) customers to switch somewhere else. Unfortunately, the migration process from TestRail to Qase is also unnecessarily difficult, especially when it comes to migrating attachments. Instead of importing individual projects one by one via XML and then having to manually link attachments for thousands of test cases, I would like to be able to use a real migration tool that uses the TestRail API to read all the information from TestRail and import it via the Qase API. (Including all attachments, shared steps, TestCase history, custom fields, references, etc.).
