Change folder of all linked images

Good morning to all 

I'm new on the community.. I would ask a little help about a problem

I've got some Adobe Illustrator files with 40 - 50 images linked.

The ai file and all the images are stored on a shared folder on \\server-1

Now i need to move all the root folder with ai files and images files to new \\server-2

But all ai files lose the link to the images.

There is a way to update all images link replacing the \\server-1 folder to \\server-2 folder?

I found out some JS script, but give some error and i'm a very newby in programming for adobe illustrator..

Version CS5 15.0.0

Thanks in advance

Luca
