Migrating projects from SoapUI-2.5.1 to SoapUI-5.2.1

Hi,

I've projects [xml files] based on soapui-2.5.1.

But I need to use them with soapui-5.2.1.

While importing the projects in 5.2.1, resource level param values and connection level param and its value is not populated.

How can I solve this issue?

Is there any automated way of conversion of projects from 2.5.1 to 5.2.1?

Thanks in advance.
