Importing testsuites into another project in soapUI

How do i share 2 testsuites (where one testsuite is dependepent on the other) to another user (User2)?

 

My Configuration:

Project1

   TestSuite1

       TestCase1
       TestCase2

   TestSuite2

       TestCaseA calls TestCase1

       TestCaseB

       TestCaseA calls TestCase1

Steps done by User1(exporting user):

1) Export TestSute1
2) Export TestSuite2
Steps done by User2 (importing user):

1) Import TestSuite1

2) Import TestSuite2

Results and issue:

1) TestSuite1 is successfully imported

2) TestSuite2 is not successfully imported as the dependent testscases (TestCaseA and TestCaseB) are broken.

Error during importing mention "Missing Test Case".

Thanks and Cheers.
