Ping! This question seems to have slipped in the global bitstream unnoticed :-)

Hi, we are looking at upgrading our 2.7.0 Swift cluster. In the past I've modeled this on a dev system by upgrading storage nodes one by one (using 2.17 as the target version). This seemed to work well - I deliberately left the cluster half upgraded for an extended period to test for any cross version weirdness (didn't see any). However I'm wanting to check that I have not missed something important. So my questions are:
- If upgrading from 2.7.0 is it safe to just grab the latest version
(e.g 2.23)?
If not is there a preferred version to jump to first?
Is it ok for the upgrade to take extended time (e.g weeks) and
therefore be running with some new and some old storage nodes for that time?
