Export DB from 1.3 and import to 1.4. Is it possible?

[Yury]

Hello!
I am just wondering is it possible to export database from 1.3.xx and import to fresh install of final version 1.4.17?
Of course it is required to copy all product images to new install.
I have tried few times but unsuccessful (lots of SQL errors). Also I have noticed that new version have new columns in product table.

Have anyone tried make it work this way?

Hi,

It is possible to export the database from 1.3 to 1.4, however it does depend on how good you are with database admin.

I know going from 1.2 to 1.3 there are a few core modifications to the database tables. While I have not migrated 1.3 to 1.4 yet, judging by the mass improvements, I am guessing similar changes are required.

Why not just let the prestashop upgrade script perform this for you? Just be sure to take a backup of your current database and save it offsite somewhere. I have performed several upgrades to v1.4 and the prestashop upgrade has worked flawlessly so far.
