OCAD subscription method of of licencing means updates are continuous for the life of your licence, not just the 3 year version cycle. See OCAD wiki for What’s New.
Volume discounts: Discounts for 2 or more of the same edition (e.g. Orienteering) are built into the pricing. If updating multiple v11 and/or v12 licences, some to single-user and some to team of the same edition, then you will attract maximum discount by creating a line item for each update type in the one order.
Upgrade to higher edition:There is no longer an upgrade path (e.g. Starter to Orienteering) while updating from v11 or v12 to OCAD 2018. You just start a new subscription for your preferred edition and retain your current edition. However, consideration will be given to including any Starter if you are updating Orienteering editions to OCAD 2018 — please contact me to discuss.
