When I upgraded I had only one problem... The way to specify a transport type in the config file for server and client (I believe?) changed from: option transport-type tcp/client to: option transport-type socket option address-family inet See the wiki page here: http://www.gluster.org/docs/index.php/Changes_from_1.3_to_1.4 Other than that everything worked great. I tried rolling back to 1.3 at one point too and that worked fine, so if you needed to go back it should work...

Is migration from 1.3.x to 1.4.x transparent? Can I use the same pre-populated backing store from 1.3.x, with xattrs set as 1.3.x set them? Or is a backup/restore required? And if there is a problem, is the downgrade path clean (i.e. can I just put 1.3.x back if 1.4.x goes wrong for me)? Are there any changes to xattrs used/set that can cause compatibility problems? Thanks.
