I am facing a strange issue. Whenever I take backup of SharePoint site collection and move it from Model Office to Production System, the tags with the documents become inactive. When you open the document properties and have have a look at the tags, you will see that tags are there but are in RED color, if you just delete 1 character the suggestion for the tags show up. This way you can again link the tags back to the documents, but with documents growing to a size of 5000 it is impossible to do this.
I have check the metadata admin configs, metadata existence, terms sets and terms existence, everything is okay, yet the tags do not link up on restoration.
Any help in this regard is highly appreciated.
