Update path from 3.x to 4.x

[webdesigner]

Hi,

The repository of my customer has about 10GB indexes and he want to update from Alfresco 3.1 to Alfresco 4.

Unfortunately I didn't find anything about the Update Path for Alfresco 4.x in Alfresco Wiki. This document:
http://wiki.alfresco.com/wiki/General_Upgrade_Process

contains only update path to the Target Version 3.4.

Does any update path exist? Or should I simple replace Alfrsco/Share war, merge my configuration files and start Alfresco?

Best regards

Thanks in advance

Can anyone help? I think this question is an important issue for every existing Alfresco customer.

Hello,

Is it right to use this update path from 3.1SP1 to 4.0:
1. Version 3.1 SP1 to Version 3.2 SP1
2. Version 3.2 SP1 to Version 3.3 SP1
3. Version 3.3 SP1 to Version 4.0

Best regards
Vitali
