I would go with one version upgrade at a time. What operating system is this deployed in?

wow 4.0.1? Was that pre-beta grafana?

JFYI

There is a technology stack changed somewhere starting from version as the Frontend started to use Typescript and Backend is on GoLang

It will be expected that with other minor problems/issues you will also notice warnings and errors that Dashboard is not supported etc and the reason is above :point_up_2:

I would very highly recommend to perform the upgrade on a dev machine instead on the production one and create all the backup for both the database and also your Dashboards with each incremental update (as @yosiasz already suggested).

This way you which was the last version and where things totally cannot go forward.

Good luck with the upgrade :+1:
