I am running the relays on VPS providers so, I can choose (only) among
the versions of Debian that are provided by the services as templates.
When Stretch is release I will see if they make it available, in a
reasonable time.

I am settled anyhow to upgrade the nodes as soon as the new Debian
version is released and I have a question. I have read that I can move
the node keys when upgrading[1] and I will do that.

One thing that will change with a fresh install is the IP address of the
nodes. So, I was wondering, in general is a good thing to keep the same
IP or changing it? Because in any case, I could try and do a
dist-upgrade[2] so that I keep the old IP. I have also discovered now
that DigitalOcean, one of the providers I use, provides a
kernel-management interface[3] that could make the process easier.

So, which is preferable between the two processes where one has the
advantage of keeping the same IP (dist-upgrade) and the other not (fresh
install)?

Of course, I am assuming that I will be able to complete any of the two
processes successfully.
