Does anyone have a good module for migrate ?

What do you mean migrate? I migrated manually and I find it quite easy but upgrade to a mayor version damn. I have spent days and days and I haven't be able to do it. So if you mean about changing from one server to another server i can help you if you are stuck.
 
From which version of Prestashop to Prestashop 8 or 1.7? There is a free tool created by Prestashop team but from my experience it was a mess to migrate from 1.6 to 1.7 and I ended up doing it manually. Paid migrate tools are a complete rip off and many are buggy. If you are migrating to Prestashop 8 (like I did) I recommend a manual migration like the one Prestashop is suggesting on their website. Franckly, it was easy with phpMyAdmin.
