Is there a way to copy/move all test cases from one JIRA project to another, I have Xray plugin installed

I have tried different things and I know there are two ways of moving test cases from one Jira Project to another. 1. Manually move each test case by using option "move". 2. Exporting all the test cases in CSV format and then Import it to new project.

The problem with: 1st approach is that it is time consuming as there are thousand of test cases. 2nd approach- I don't see an option of exporting test cases in csv format, I only see xml, excel and printable. And while importing test case through "Test Importer" it only accepts csv format.

Is there a better way to move/copy test cases from one JIRA project to another?
