Yes. From the Progression Server Overview page: Q: Can I transfer my existing character to Progression Servers? Generally, no. These servers are fresh servers where all players will begin their adventures from level 1. Exceptions: Players may transfer FROM Lockjaw TO Ragefire.
Yup, players should be able to transfer characters from Lockjaw to Ragefire (but not vice versa). Server transfers should be working, it's account to account transfers that currently aren't available. Hope that helps!
