Migrate self hosted server from 3.18 snap to 5.0 docker based installation

Hi!

you will need to run a docker version with 3.18.7.
Then you will restore mongo db from snap to the same version in a docker environment.

While upgrading, don’t jump majors. Go first to 4.8.4, then to latest 5.0.4

Let me know if this helps.

Thanks!
