@BardWood I don’t think it will work. The FOG Trunk methods involved with synchronizing storage nodes with their masters has greatly changed, along with the ability to now cross-share images with storage groups. I would not advise mixing versions as you would like, I think it’ll only lead to disaster. The location plugin has also been modified to cause remote nodes at a remote location to PXE boot directly from their local node. Also, the 1.2.0 nodes probably can’t support this functionality
You’d be better off just updating everything to fog trunk, OR just staying at 1.2.0 till 1.3.0 is released.
