You can now upgrade from single- to multi-platform for free.

Saw this on the site. How do I do this?

I have BC3 Pro at work on a site licence, and I run Linux at home, I was hoping to use my existing key. I know it's within the rules to use my work key on my home Windows PC, but I ditched Windows along time ago, and couldn't go back there now.... (not since the Win8/Win10 disaster)

Hello,

You will need to contact the manager in charge of your key, since it would be upgraded all at once. This would not invalidate the other installs, but would be processed as a single order and would still need to be managed.

They would follow the link at the top of this form to "Upgrade from BC2 to BC3, or from BC3...."

Please note that this article also details the date range of upgrade options. You may also qualify for a free or discounted upgrade to BC4 (multiplatform), which if applicable they can select as an option during the upgrade process.
