Identify OPC-UA tags by ID even if renamed

I am looking for information on the following question, but I can't find a clear answer (possibly not as I expect):

When renaming a tag in OPC-UA, is its BrowsePath kept or does it change? The idea would be to use it as a unique ID of the tag, and even if the tag is renamed, not to lose the relation between old and new data.

Thanks.

BrowsePath follows BrowseNames, so if these names change, also the path changes.

NodeId is the unique identifier that should not change.
