[11:02:08] <hadifarnoud> I upgraded to mongodb 3.6 but can't start it
[11:02:14] <hadifarnoud> this is the error: ** IMPORTANT: UPGRADE PROBLEM: The data files need to be fully upgraded to version 3.4 before attempting an upgrade to 3.6; see http://dochub.mongodb.org/core/3.6-upgrade-fcv for more details.
[11:02:53] <hadifarnoud> I used `mongod --upgrade` as well but still shuts down the mongod process
[11:41:02] <KekSi> read the guides on the website and then install 3.4 (since you were apparently running 3.2 before)
[11:41:39] <KekSi> also remember to set your storage engine if necessary (wiredTiger vs mmapv1)
[11:43:06] <KekSi> if you were still on 3.0 or even 2.4/2.6 then you'll have to increment by +.2 and install the old versions one after the other (all but 2.8 which was replaced with 3.0) so 2.4 -> 2.6; 2.6 -> 3.0; 3.0 -> 3.2; 3.2 -> 3.4; 3.4 -> 3.6
[11:43:14] <KekSi> it'll auto-upgrade once you launch
[13:32:31] <synthmeat> so, i can't really get mongodb >= 3.4 on distros that have libssl1.1.x?
[19:45:48] <ybaumy> i am using mongodb centos7 and want to switch to rh-mongodb34-mongodb on centos7 server which holds the other db. how to i do that? just systemctl stop mongodb-old.service and start the rh-mongodb34-mongodb?
