I've been testing the use of FileVault 2 & Mavericks clients in the JSS. I also have some Mountain Lion clients but I'll probably just upgrade them to Mavericks. So most likely I'll be dealing only with Mavericks.
Anyhow, I have several systems that are already FileVault 2 encrypted. Would it be best form and easiest to just decrypt the drives before trying to work with these systems and FileVault 2 and the JSS?
