Migration Aris 7.2 configuration to Aris 10 (Cloud version)

Hi, 

How to import the complete configuration to Aris 10? 7.2 configuration contains user defined elements (derivated model, , user defined symbol, user defined attributes....) and when I try to import it in my new Aris version, I cannot see all symbols in the Method of Aris 10. 

Secondly, I would like to move the user defined symbol aris 7.2 configuration to standard symbol aris 10. It's possible? 

Regards
