Some people reckon it can be hard to get them going again from dry, but
this applies to corms that you buy - if you're simply digging up from
one area of the garden and replanting them the same day, I couldn't
imagine they'd actually notice, so dormant seem the time to go.

Yes, but they won't BE dry if you dig them up and replant them on the
same day. :-)

I usually move mine just as they are coming into growth so I can split
them etc and see which, if any have had their day. The weather is of no
consequence in terms of the plants themselves as they are, of course,
hardy. But, naturally, you will need to be able to work the soil.
