Good day to all the readers.
Is there any way to migrate data between two Magento 2?
I think that the data migration tool doesn't allow to do that.
Thanks in advance.
EDIT 1: EXPLANATION: I have an old Magento 2.2.7 version and I have to migrate to a 2.3.4 version (not 2.4, for unexplained customer reasons) the new version contains a new theme and a completely different logic. I didn't start from the original database because I didn't have access to the production database when I started developing the theme.
