So, there's been a fair bit of chatter on the list about upgrades failing. I haven't paid close attention, but IIRC, upgrading from 4.7 to 4.8 or 4.9 caused problems. So, just to clarify - this is an in-place upgrade that is failing, correct? Does this apply if, instead of an upgrade, one provisions a new DC on, say, 4.9 and joins it? In short, will this allow you to get your DCs to 4.9 by creating new DC's on 4.9, and then demote/remove all the 4.7 DC's after the new 4.9 DC's are synced etc? It's just not clear to me, given the stuff I've seen on the list. TIA -Greg

Am I misunderstanding things? If there are substantial interop problems between versions of Samba, is this documented somewhere. I guess I was assuming that given some recent version of Samba, it would sync with any other current version of Samba and allow the FSMO roles to be transferred. And yes, I get that doesn't really solve the distro upgrade problem, but if it was a given that you could spin up a new DC and sync, then transfer FSMO roles - well that would go a long way to assuring a reasonable way around the problem. (At least until a good understanding of the problem was wide-spread and a solution found.) Please tell me I've misunderstood this! :) -Greg
