Move old data from woocommerce to new.

Hi. I need someone who can help me and move existing orders and customers from my old WP woocommerce page to my new Wordpress page. I have tried to do it myself but I do not get it so that all products are moved. It is important to me that you who do this are professional and have done before. I have been trying to do this for two days without success. I have managed to move 1000 orders but there are still 1000 orders missing. I have tried to turn away from all imports but it is not possible to get it maybe something is wrong.
