Users had the choice to opt in or opt out of migration. If you opted in, your photos would have migrated automatically to revel. The account uses the same username and password as your photoshop.com account.
In the US, opt in was the default. Users had to opt out if they did not want migration. Outside of the US, opt out was the default, and users had to opt in to allow migration.
My guess is that you did not opt in to migration. You can upload your photos from your computer or device to revel and begin using the account anytime. If you need resources, please see the links on this page:
