What do you mean by “changing my database”? If you created a new database and imported the sql file you downloaded from your old database, were the CS-Cart versions the same?
I face exactly the same issue. I want to upgrade my store from 1.3.5 sp4 to last version.
The trouble occurs when uprgading from 1.3.5 sp4 to 2.0.8.
I must dump the database from 1.2.5 sp4 (no trouble for that).
And then, go to 2.0.8 new database (clean install with demo data), and import the dump.sql I created in the step before. As there is an important chage in data structure, I must launch a specific php script provided by sccart team.
But When importing dump file, I obtain this message :
Deprecated: Function set_magic_quotes_runtime() is deprecated in /homez.44/myshop/www/v208/prepare.php on line 53
