Parsnips will not like being transplanted if it means separating them and disturbing the roots. I collected around 50 toilet roll centre tubes and made a wooden box to house them, then filled them all with compost and sowed 3 seeds in each in February in the greenhouse, pricking out the 2 weakest in each station after germination. These then grew on in their stations until they were ready to be planted out in April. They are now growing very well in their final positions.
The pic above shows the box with the thinning out done. It is important in my opinion to add a copper strip around the box to deter slugs and snails as they love to eat the tender young plants. If they do get over the copper strip ad a second strip below it and connect a pair of wires to the strips and connect to a small battery And that will guarantee they will not cross!
The cardboard tubes are best planted out with the seedlings and they will just rot down in the soil. Hope this helps
