Upgrading Prestashop 1.4.9.0 to 1.5.6.1

[cassim]

Hallo thier

 

I have a 1.4.9.0 PS, that i want to upgrade or make a fresh 1.5.6.1 doing to some errors in the code.

I have a database with lots of order/customer and products, that i want with in the new 1.5.6.1 PS.

 

So what i need is the following:

 

How do i get all my prestashop informations over in the 1.5.6.1, upgrading or a new install .??

 

 

I have tryed the following.

I have tryed to follow guides from the forum on how to manual upgrade from 1.4.9.0 to 1.5 without any luck in the database. 

 

I have tryed to use the 1-click autoupgrade, but with that i keep getting lots of errors.

Error 1.

When opening the autoupgrade thing i get this error

unable to create file /data/home/customda/public_html/cassim/autoupgrade/backup/index.php

Error 2.

So when pressing the upgrade i get the following error below

Javascript error (parseJSON) detected for action "upgradeNow".Starting restoration... 

What to do ?

How do i get this working for me. ?

 

The most important for me is that i can get the following content with over in a new site.

• CMS content
• Products / Category
• Customers
• Orders
• Module settings

All other information is useless, just this 5 points. 

 

Hope you can help me or bring a point up for me how to fix it.

Hi

 

Sorry I can't help with your problem .... I am actually looking for help on the 1 click upgrade myself and have not received any replies from my posting!

 

I have 1.5.4.0 and wanted to know how to use the 1 click upgrade and to know what to expect before trying it?

 

I'd appeciate any advice on upgrading.

 

Thanks

Hi

 

There is a bug in auto upgrade module it seems which makes you lose some orders when migrating to 1.5.6.1 .

 

Look here : http://www.prestashop.com/forums/topic/298290-bug-in-prestashop-1561-upgrade/

 

I suggest not to upgrade till this is fixed.

Hello Trolar!

 

Regarding your problem with upgrade. As an alternative way you may try Cart2Cart. It allows to move products, orders and customers from one PS installation to another. Unfortunately it won't work for CMS content and module settings. Check this page for more detailed info.
