I'm in the middle of a joint so hang tight, what comes next could be totally whack
From my experience, it really depends how long you need to veg for which would determine the manner in which you were going ot do it if transplanting to a waterfarm was the aim. I've found with DWC buckets that the roots will grow through the netpot fairly rapidly, they're in search of that reservoir. If you are able to transplant at this point, that's great, but if you need to let them go further it oculd potentially prove problematic.
Personally, i would stay clear of DWC for veg, and rather build a small ebb and flow table. The idea would be to add an extra bucket to it though. So instead of having your bucket and your reservoir and the gubbins, you add a second bucket into the first one, but one that is HEAVILY holey for all the roots to grow out of, like in the waterfarm bucket, and then you can veg for as long as you like and roots will stay in the bucket, then come transplant, you lift the holey bucket up, plant, and just plop that into the waterfarm. All roots will have grow inside this bucket but once out of the constricting outer bucket can now grow out the holes
I guess that's more one of those long term options. Look at me and my creativity go, zooom. I think my mind went so fast i jsut started waffling about somehting not really what you were after haha

When you have a good idea, take a step back and make it that little bit gooderer.
