Hi! It will depend on your deployment method.

But a good rule of thumb here is to backup your mongo db, spin up a docker deployment with the same version you are using, restore data, and start migrating.

note that the dump/restore will be necessary, as for newer versions, we are deprecating the mmapv1 storage in favor of wiredTiger:

> Migrate your existing MMAP based MongoDB instance into a WiredTiger one without with as little downtime as possible.

Hi!

how have you deployed?

Using snaps or manually from tarball?

Please, consider migrating to docker running in centos as this will get you the same environment as the majority of our user base.

I’ve used this link [https://docs.rocket.chat/installation/manual-installation/centos](https://docs.rocket.chat/installation/manual-installation/centos) before to install our rocketchat

That doc has moved to here:

> **[Rocket.Chat in CentOS](https://docs.rocket.chat/quick-start/deploying-rocket.chat/other-deployment-methods/manual-installation/rocket.chat-in-centos)**

Installing it from tarbar/manually is the hardest way possible, as you’ll need to take care of all dependencies, node version, etc.

in theory 🙈 this doc here may help you, but a lot can go different:
