How to upgrade the druid cluster from a very old version (druid- to the latest version?

Hi :

I have a running druid cluster, the version is, and I want to upgrade it to a newer version, although it is now running very well.

My question is I do not know if I should be upgraded step by step or directly to the latest version?

Thanks in advance for the help…
