I agree - if you can avoid it then not in flower, however, in this case they will do sooooo much better if in good furtile soil and enough room to spread so I would replant ASAP.
I only planted my strawberries a couple of weekends ago as I had overwintered them in small pots (moving them from one allotment site to another!) and they have already put on quite a spurt of growth.... go for it
