Up/crossgrading from PT 12.4

[HenryScow1]

Hello.

I have PT 12.4, which I bought outright some years ago, and for which I have no subscription, support contract or anything. I am currently running Win7, but the time has come to upgrade to Win10.

However, I don't know the best way to proceed with up- or cross-grading my version of Pro Tools. I've had a quick look on the Avid store and found the following:

https://shop.avid.com/ccrz__ProductD...&sku=DYNA00000

Could someone confirm I'm looking at the right page, and that paying for this will mean I can then upgrade PT and then Windows? If the best thing to do is to pay for and raise an Avid support ticket, then I'm happy to do that, but I thought I'd ask here first!

Thanks

Henry
