Chnge multiple X-Ref File names within multiple drawings

Hi Good Afternoon, evening, morning,

I am looking for any assistance possible, as from the title i am looking at some kind of Lisp code that will change the X-Ref file name from 'x' to 'y' for multiple x-refs on multiple drawings.

Case history.....

Our office in Hamburg has a huge number of x-refs (3000) that have been created and we now wish to update the x-ref file name from a German based accronym to a universal accronym for our global offices. Is there a way that when we open an existing drawing containing x-refs that the Lisp function would rename the x-refs to the new x-ref file name?

once we have renamed the x-refs we are lookling to relocate them on an international file server for all offices to use, i belive that reference manager can be used for this, its the x-ref file name renaming that has me stumped

I would appreciate any assistance where ever possible....

Many Thanks

Kind Regards

Simon
