Depending on the environment, upgrading regularly could actually 
increase uptime.

Would you rather:

- Upgrade regularly, with a small version jump (e.g. 4.15 to 4.16), and 
figure out which change causes issues when there are issues?
- Upgrade incidentally, with a large version jump (e.g. 4.12 to 4.16), 
spend time figuring out which version causes issues when there are 
issues, then figure out which change in that version causes issues?

If you upgrade regularly, you could have issues more often. However, 
those issues would be solved more quickly. Bottom line: your uptime 
could actually be higher. Figuring out the difference between two 
versions is easier than figuring out the difference between multiple
