I just created a droplet with Fedora 24 on it. I have three older droplets with Fedora 23 on them.

What is the best way to update the older ones to 24 as well? These are the two approaches I can come up with:

1. Create new droplets with F24 on them. Backup the data on the old droplets and move over.
2. Run dnf distro upgrade within the F23 droplets and pray that all settings etc. are carried over in the process.

Option (1) is very labor intensive, but I'm afraid that option (2) will result in a suboptimal end result (old and new settings next to each other, possible conflicts).

Any experience/advice on this is highly appreciated!
