Data generated using Catia V5R30 shows no geometrical sets in Catia V5-6_R2018

Hello Everyone, 


I am facing a probelm with the data generated in Catia V5R30 version. This data has to be imported in the Catia V5-6_R2018 version but the geometrical set that i have created (as seen in the left side of the picture) cannot be imported perfectly. The geometrical sets are lost. 

I was suggested by someone: If i import the file to 3D Experience and then export it to Catia V5-6_R2018 version, it should work. But i do not have the 3D Experience licence so i was hoping to try out the Trial version.  


Any suggestions what could be more effective way of solving this problem.

Thanking you in advance!
