Upgrading Lightroom from 5 to 6 on new Mac

[loganr81893067]

Hi there!

I own Lightroom 5 on PC and recently purchased a MacBook Pro with Sierra. I've heard there are tons of issues trying to run 5 on this OS, so I'd like to upgrade to 6. I'm aware that you are able to select "upgrade" for $79 from the download page, but here's what I need to know:

How and when will I be verified as a Lightroom 5 owner?

I have the serial number. But the program is is not installed on my Mac and for whatever reason I can't get it linked to my adobe id.

My worry is that I will pay for the upgrade and be unable to authenticate my licence for 5. If it only asks for a serial number I'll be okay, but if it requires a linkage to an adobe id I'm screwed and I can't know this til after the credit card payment.

Thanks in advance for your response,

Logan.

You'll need the older serial during the installation. To confirm that you are eligible for the update version when entering a update LR6 serial you'll be asked for a old LR serial.
