I would rather suggest you to concentrate on Magento or PrestaShop not both of them. Simply choose the one that suits you better and move the other store to the platform you need.
Since both solutions support multi-store you can just create a substore/store view and migrate all the data from one shop to another. As a result, you will receive a single admin panel for two shops. It will allow you to concentrate your efforts within a single shopping cart and reach better results in your business.
This type of migration can be easily done with Cart2Cart. If you have any questions feel free to contact our Support Team.
