Hi there! To answer your questions:
1. Your Behance profile will not be affected once your Prosite website is down. Please make sure the Adobe ID used on your Behance profile is the same one you are using for your Adobe Portfolio site.
2. If you're already paying for Prosite though Adobe with a Standalone, Single App, or Full Creative Cloud membership, your Adobe Portfolio membership is already included. Although most users can only purchase Adobe Portfolio through Creative Cloud, we are making an exception for active ProSite users. So, you can simply login to Adobe Portfolio with your Behance + ProSite Adobe ID and publish. Your ProSite subscription (at $11/month) will continue to renew monthly and pay for this product. Currently, you are getting a “two for one” (ProSite and Portfolio) as part of this cost.
*** If you're not currently subscribed with Adobe (our old YEARLY plan) you can purchase a new Adobe Creative Cloud Plan (starting at $9.99/month) when you publish your Adobe Portfolio.
If you'd like to cancel your Prosite subscription and purchase another Creative Cloud subscription, you can do so here: Creative Cloud pricing and membership plans | Adobe Creative Cloud
I paid for prosite and I have created a new webpage in Portfolio now but Adobe is asking me to pay for the site. I don't think my subscription has been transfer. Please PM me.
There could be a few reasons for this, but we can take a look if you reach out to help.myportfolio.com!
