Kontakt update

I personally can not guarantee that you will experience zero problems upgrading since I do not have enough knowledge on the subject. And also the resident N.I. Customer Care expert (an Mac expert) is not here today and will not be back until next week.

What I do know is that for project auto-migration to work then you will have to have Pro Tools 12.3 (and higher) , reference : Notes about Auto-Migration of Kontakt Versions in DAW Projects

Also if using Komplete Kontrol plugin then you can de-select the Always use the latest plugin version in K.K. settings.

Notes about Auto-Migration of Kontakt Versions in DAW Projects :

What does this mean for my old and new projects?

1. If you want to keep using an older Kontakt version in your existing DAW projects, you don't have to do anything. You just have to make sure that the older Kontakt plug-in is installed and seen by your DAW. You can install Kontakt 7 / 8 additionally, if you prefer using it on newer projects.

2. If you want to migrate to Kontakt 7 or 8 in DAW projects that contain older Kontakt instances, please uninstall the older Kontakt version.

Please note that Kontakt 6 is named "Kontakt".

Windows: Auto-migration works down to Kontakt 3.5 on Windows. The Reaper auto-migration works back to Kontakt 2. For Pro Tools AAX, migration works down to Kontakt 5.1.0.

Please uninstall your older Kontakt version as shown in this article. If the auto-migration doesn't work, the Kontakt plug-ins have been moved after the installation. In this case, please check which VST folders are scanned by your DAW and remove the Kontakt plug-ins manually from those folders. Please see the "References" below.

macOS: Auto-migration works down to Kontakt 3.5 on Mac. The Reaper auto-migration works back to Kontakt 2. For Pro Tools AAX, migration works down to Kontakt 5.1.0.

Please uninstall your older Kontakt version as shown in this article.
