I currently have Adobe Lightroom 5.7 - how do I upgrade to Lr 6.0?
You will have to purchase the upgrade to Lightroom 6 which would cost $79
Refer this link for purchase : Products
It is important to note that LR 6 requires a 64 bit operating system. So if your OS is still 32 bits, you'll have to remain at LR 5.7.1.
