What is the goal of the mongodump for 3.9.12 -> 3.10.2? #10

Hey @exsilium, I co-maintain another unifi-video docker image w/ @pducharme and I'm trying to understand the problems w/ 3.9 to 3.10 upgrades. What is the goal in your dump / reload? I think it is probably just migrating from mmapv1 to wiredTiger right?

I'm trying to figure out an issue where my currently running 3.10.1 instance is already wiredTiger engine, but when I just upgrade to 3.10.2, it claims the users table is corrupt. Back to 3.10.1 and it works fine again.

Hi @fryfrog , Up to v3.9.12 the MongoDB version used is 2.6.10, The v3.10.x images are on Bionic Beaver and with the new Unifi controller the MongoDB version is 3.6.3. The dump / reload was required to ensure proper migration between the engines.

If you are already on 3.10.1, however, I don't see any specific reason why the upgrade path would fail. But just in case check if the MongoDB versions have changed in between.

Our Docker image has been using MongoDB 3.6 or newer for awhile, mine's actually running 4.0. It's probably worth downgrading. Thanks for confirming what your dump/restore was for.
