SiteCollection Column Mapping / Chance ID

Hello,

we have a SharePoint Foundation 2010 Server with one Site Collection (Collection A), some Sites, Doc-Libs & Lists and unique Columns which are present in the document (via quick part).

Now we created a new SiteCollection (Collection B) (we want to restructure our SharePoint) with same called unique Columns, but the ID of the column is different to the existing column in the collection A. So if I upload a document with quick parts, the Connection to the new column ist lost and the visited value isn't up to date in the document.

Is there any solution for this problem? Can I easily Change the ID of the new column to the ID of the old one? Or is it possible to map the columns from Collection A to Collection B?

Thanks!!
