Old Dahlia Tubers

The good news is that last year's tubers survived the winter. The question is how do I replant them in pots. They are solid and dry with no shoots yet, do I just replant them in pots and keep in my shed (no greenhouse) and ? do I add any water (mixed opinions with no roots or shoots) or do I just cover with a little compost until shoots appear and then replant them in which case do I add a little water to encourage the tubers to produce new shoots. Presumably I should keep the pots in the shed until risk of frost has gone.
Once the shoots appear, it's best to move them somewhere where there is light, as well as protection from frosts. You can then start thinking about a liquid feed every week or so, and increase the watering. I'm in the South, we won't put the pots outside until around May/ early June, when risk of frost has passed.

They will go into a cold g/h, in barely damp compost and will not be watered again until shoots appear.
It's a big job, I have over 60 tubers.
