if I was in your position, I would use `docker inspect` on the two containers, to help me rebuild a docker-compose.yml and .env file.
Once I have that I would make a snapshot and then test `docker-compose down` and `docker-compose up` to check that it is working. (don’t use ‘latest’ in any image tags)
Next I followed this script to upgrade my mongo DB version. Maybe it helps you:
```auto
#!/usr/bin/env bash
read -p "Are you sure? (y/n)" -n 1 -r
echo # (optional) move to a new line
if [[! $REPLY =~ ^[Yy]$ ]]
then
[["$0" = "$BASH_SOURCE"]] && exit 1 || return 1 # handle exits from shell or function but don't exit interactive shell
fi

Hi @stefan.badenhorst !
Thanks for sharing your work with us! We really appreciate it.
At the end of the day, migrating Rocket.Chat mongo versions will usually by a dump and restore process.
This script makes it easy, as it will dump and restore.
Thanks for sharing 🙂
