Certain NI products qualify for discounted updates and upgrades to the various KOMPLETE 13 bundles. You can find the list of products and their possible upgrade paths in this article.
Note: Read this article to learn more about the concepts behind crossgrades, updates, upgrades and their base products.
Unfortunately it is not possible to upgrade more than one base product to a bundle of 68 instruments (KOMPLETE) or even 118 instruments (KOMPLETE ULTIMATE). We recommend selling the redundant single components (except the qualifying base product) and purchasing the newest version of KOMPLETE 13 (ULTIMATE) upgrade. Registrations from our software products can be easily sold and transferred to another user. You can find more information about selling your Native Instruments product in this article.
