We're planning to do a full revamp for one of our customers.
Instead of just updating the current store and add a new theme we're planning to start from scratch.
The current store is running for over 5 years. There have been lots of modifications that are obsolete. Code changes that are obsolete and probably some issues due to custom modifications.
To fix all that we Install a fresh 4.12 version. Add Unitheme. Setup everything the way we want.
So far, all good!
However, when that is done, we need to migrate all data like:
Orders / Products and all their images and options / Customers and their settings.
What whould be the best/easiest way to do this?
Thanks
