VC migration from 7.0 to 7.3

HI All,

We are trying to migrate from  VC 7.0 to 7.3. We have pretty complex application with multiple nested views and union. In 7.0 everything is working fine and we have multiple output signal which has a same name( with filter and with table) when I migrated to 7.3 using migration tool It changed  duplicate output signal name as “_name”  . When I try to deploy its say’s the “-name “Event name is not defined.”  Since we have Union with 18 ports. Not sure how to fix this issue.

Any suggestion on resloving this issue  will be very helpful.

Thanks in advance.
