Environment version selection not present while export of solutions in v9 CRM trial

Hi All,

Asking for help for an issue in v9 version. 

I am not sure if the old functionality still exists or not. Exporting a solution for a specific Dynamics 365 version. I have developed a solution in v9 trial version and trying to export the solution for my environment which is in 8.2 version. 

Can anyone provide the solution for it? or I need to create all my components manually in degraded environment and then try to export the solution
