Bom upgrade

Hi please can you tell me I am upgrading my first gen 1000 mm Xcarve If I am buying this upgrade can I buy the boom as my boom is two piece will it make any difference in a two-piece or a one piece boom after the upgrades (side height z motor) hopefully it will be a 2020 new machine but as I’m going to the trouble of upgrading it do I need to upgrade the boom or is the two-piece boom adequate if I need the boom can anybody tell me where I get the boom from and how much it is thank you
