### Description

I want to upgrade my installation from 1.2.1 to 2.4.0.

Can I do that directly or first upgrade to the latest 1.x (which seems to be 1.3.2), then 2.0.1, then 2.4.0?

Or do I even need to go from 1.2.1 → 1.3.2 → 2.0.1 → 2.1.3 → 2.2.1 → 2.3.2 → 2.4.0?

Would I have to upgrade MongoDB from 3.4 to 3.6 first or should I do that later?

### Server Setup Information

- Version of Rocket.Chat Server: 1.2.1
- Operating System: Linux
- Deployment Method: bare metal

our network operation center did it like this:

- stop all docker containers
- upgrade MongoDB to next 3.x
- stop MongoDB, start. If successful: `docker exec -it root_mongo_1 bash -c 'mongo --eval "db.adminCommand( { setFeatureCompatibilityVersion: \"3.x\" } )"'`
- as soon as MongoDB is on 3.6, upgrade the Rocket.chat docker container step by step as described in my OP.
