Update relationships between objects

good morning all,

I would have a question please.is there a report which allows to export / import relationships between objects in already created models?

I have used export attributes for translation and import translated atributes. in the xls file genrated with this report there is a worksheet named connections but it is empty and even if I update it it will not be imported. probably this report is only updating the attributes, however I would like to understand if there is a way to chnge objects relationships in bulk based on the objects GUIDs just to ensure data preservation. in my case I need to preserve those GUIDs as they were initially created and find a way to modify how the objects are used.

Thank you
