Export old database prestashop version 1.5 to 1.6

I was hacked 2 days ago. Now my old website is offline. The only staff I could keep are the databases. Now I reinstalled prestashop version 1.6.1.6 with a new theme. I need to reimport in the new version database, all customers data (login, password, history, etc.), logo, categories, products description, stock, metas description, titel and all the rest that is possible.

I need to come back live as soon as possible.
