migrating cores with Solr upgrade

Hi,

What is the best way to migrate cores from an old version of Solr (say 5.x) to a newer version (say 7.x). I did not find anything pertinent to the matter in the Solr reference guide.
Is there a tool that can do that seamlessly?

Regards,
Piyush.

Oops fumble fingers. Anyway I'd recommend completely reindexing into a new
collection.

Lucene does not guarantee back comparability over two major versions, so
I'd recommend completely reinde
