Hi- it would probably be best to remove the upper cordon and use that wire (and maybe additional wires) to tie shoots arising from the lower cordon.

Take a look at this page on VPS:

And more general pruning/support information:

Thanks Jon for your support. I will remove the upper cordon and concentrate on the VSP from the Lower cordon that needs to be established. If needed, I will keep/use a second trunk that was created/grown from last year's pruning (kept 2 buds) at the bottom of the vine for the right or left low cordon of a bi-lateral lower cordon. I will also need to setup a means to add and hold the catch wires.

Still learning, last year there was too much growth due to poor pruning (a lot of the flowers dried up and fell to the ground). Additionally, on my Somerset vine there was fruit on the vines in the fall that did not ripen.

Again, sincere thanks for your support.

Joe

Glad to help.
