I recently performed an update from the exact mentioned version 17.2.3 to .5 using cephadm.
Like you, I was extremely concerned that something could go wrong since I have very little knowledge of what happens in the background. However, there were no problems :) I worried for nothing. Nevertheless, you should make sure to have backups of the most important data. I love ceph but also have a huge fear that something might not work and about 1.5PB of data (raw) might disappear...
