migrate a project developed under Borland C ++ Builder 5 to another IDE (Qt or VS)

Good Morning

Internship, I would like to migrate a project developed under Borland C ++ Builder 5 to another IDE (Qt or VS), also have your opinion on the feasibility and the different phases that you could advise me,

I began to focus on converting borland c ++ to Qt, initially VCL -> Ui (Qt), already tried DFM2QT but converts 1/4 of all Dfm files to Ui files – QT So I come to you to offer me your opinions, ideas, experiences …

Thank you in advance !!
