Normally, the metadata should still be in the database, the .xmp sidecars are 
there for exchange with other programs and to provide some data redundancy.

So why not just rewrite the metadata to the sidecars? 
Why do you think that is not safe? 

What's unsafe is writing metadata to raw files, as errors can make it 
impossible for raw editors to read the file (I expect that to be rare, but 
I've seen some reports about it happening). And of course, writing to any file 
ca go wrong occasionally, that's why we make regular backups.
