I’ve a few days of data (only) using the June 15 sd card image system. I’d like to upgrade to 3 May sd card system. Is there a recommended process for doing this, which minimises down time - or is it a matter of backing up what data I have, re-flashing the sd card, doing any jessie updates, expand…

Recommended upgrade method

The export / import backup module can be used to migrate from the June image. See instructions:
