Update from 1.4.3 to 1.5.3.1

[design1]

Hi there,

 

I've installed a 1.5.3.1 prestashop version and I would like to get my orders, stats, products and users on this new installation from a 1.4.3 prestashop.

 

Is it fine to just export tables from the old database (1.4.3) to import them into the new database (1.5.3.1)?

 

The reason I'm doing the update that way is because the autoupgrade plugin failed and also I want to have the new theme along with my previous custom one. (When I used the new theme, it was still using old hooks positions, so I guess it's in the database and also in modules).

 

 

Hope I'm clear enough

 

Regards
