We're upgrading (Sernet) Samba 4.2 to 4.4. As recommended on this page: https://wiki.samba.org/index.php/Updating_Samba, I have upgraded one of out 2 DCs, the one that does not have any FSMO roles. We will spend the next week making sure everything works as expected. So far, so good. One thing I'm not clear on is whether I should move the FSMO roles to the upgraded DC before upgrading the other one or if it doesn't really matter. Can someone please shed some light on this? Thanks. regards, John
IMHO: no real need to move FSMO before upgrading FSMO owner if no real load. FSMO are roles which make one DC different of others DC on one specific point (for each role). As long as you don't do something which requires FSMO role you won't use FSMO roles, so no matter. Things which triggers FSMO usage are modifying the schema (don't do that during upgrade), reaching RID pool limit on non-FSMO DC (don't add bunch of users during upgrade) and so on. These are examples, roles are 7, each is triggered in different way. 2016-07-25 7:12 GMT+02:00 John Gardeniers <jgardeniers at objectmastery.com>:> We're upgrading (Sernet) Samba 4.2 to 4.4.
