100% content pairing from old prestashop web 1.6.x to new prestashop 1.7.x

Dear you all. Actually I have a website that is active in PS 1.6.x with Alysum theme and some contents. There is another staging web PS 1.7.5 just ready and active with a basic content migration. What I need it to do a full 100% migration. Except for modules that are not more available in PS1.7 (of course) but it need to pair and check also some data that are nor visible in BO and -indeed- are in the DB: merchant expertise data, conenction and guest data etc the BO of 1.7.5 should be with no errors and with the history of the BO of 1.6.x contents (rev slider, menu, simple blog posts) and footer blocks with links must be paired in all 5 languages. All the info and data are well presented in the 1.6.x BO obviously, it's a simple job but only for people that well know PS 1.7
