I wonder if one can install pro tools 9 and then upgrade to pro tools 12. If pro tools 9 dont work on os x el capitan how am i then going to be able to upgrade to pro tools 12? Is there some problem in this or is it going to work?

Thank you for answears!

You do not need to install the program to upgrade.

One of two things will happen (or both).

1. If you purchase the Pro Tools 12 upgrade, you then need to surrender your Pro Tools 9 license in exchange for a Pro Tools 10, 11 and 12 bundled license. This all happens within the Avid account and iLok licensing manager

2. If you already own (Pro Tools 12) and the license is accounted for (within your iLok), then you do not need to install 9 to install 12. If anything, completely delete 9 before installing 12. Both apps cannot live under the same OS etc...
