"Free-hand SQL connection problem" while converting Deski reports to Webi reports

In BO 6.1 To BO XI 3.1 Migration (Import Wizard)

I have some free hand sql in a Deski report, this runs fine.

But While exporting this to the repository to get this report converted to Webi.
Checking the report it in the repository i can see it and refresh it.
 

But when i try to convert this report i get the message;
 
Not converted: [rep name] - Free-hand SQL connection problem
 
Some other reports with other than free hand sql reports got successfully converted or partial converted.

After analysis i come to know that in webi free-hand sql reports not supported so any solution for this migration?
