Depends on meaning of "is it safe" ...

This is bugfix only upgrade, so in general Cassandra should perform only 
better _after_ upgrade.

On other hand, _during_ upgrade, you have to restart all nodes. Assuming 
having data inconsistency among nodes, you may get different query results 
(old/missing data, etc...) during node restarts.
