You gotta have the authorization codes for every domain you want to transfer out. The easiest way of obtaining this code is by creating a 2nd registerfly account, and pushing the domains to your 2nd account (that way you'll be able to get the codes, and you'll be free to transfer to your new registrar). Steps are below:
1. Create A New Register Fly Account.
2. Login into the Old RegisterFly Account.
3. Click on Manage Domains
4. Click A Domain Name
5. Click On Change Ownership
6. Click On "Push your names to another user"
7. Click Continue
8. Enter The User ID of The New RegisterFly Account
9. Verify The User ID of The New RegisterFly Account is Correct
10. Click Continue
11. Select Each Domain Name to Push
12. Check the Check Box Marked "Change the Whois/Contact info on the names being pushed"
*** Check This Box Only if your Domains are Showing ProtectFly Information on a Whois Database, If it's Showing your Real Information with Working Email Then Continue Without Checking the Check Box ***
13. Login into Your New RegisterFly Account, Your Recently Transferred Domains Should Be All Unlocked.
14. Click Change Whois Information And Get Authorization Code for Each Domain.
15. Begin Transfer to New Registrar.
I just did it for a handful of domains and it was pretty easy
