Dspace-CRIS over Dspace 6.3 installation

[gonzalo....@gmail.com]

Hi.

I have a functional Dspace 6.3 jspui installation with several documents loaded.

I want to install CRIS on that Dspace that is already running and working.

I have followed the instructions according to this link:

https://wiki.lyrasis.org/display/DSPACECRIS/Installation#Installation-UpgradeanexistentDSpace(notCRIS)installation

But I think I am not clear about the structure of directories and subdirectories that this link talks about.

When downloading the file "DSpace-dspace-6_x_x-cris.zip" I have the entire structure of a Dspace and that gives me an error with the current and active installation that I have.

Has anyone been able to upgrade from 'normal' Dspace to a Dspace-CRIS that can answer some questions for me?

I have searched for a step-by-step tutorial but found nothing.

I have not found current information on that topic and what is there is too old for the version of Dspace I use.

thank you very much, Gonzalo
