Reorganising company-wide assets used as linked files in Indesign

My company is contemplating a reorganisation of our file system.

Our design team has approximately 2000 indesign files full of links to external assets found on our file system.

Many of the assets are used in multiple indesign documents.

Is there any scripted means of changing the asset links across all indesign files at once?

I am aware of the package process but, this would create lots of duplicate copies of the assets, and would require us to manually package over 2000 files one by one!

Are there any other approaches?

Thanks

Brendon
