Version upgrading : The correct sequence?

[cocoa]

I would like to upgrade CrateDB from version 5.6.3 to version 5.10.6.

In the recommendations on GitHub I find written in the release notes “We recommend that you upgrade to the latest 5.9 release before moving to 5.10.6.”.

Does this mean that to upgrade from 5.6.x to 5.10.x I have to upgrade each cluster node from 5.6 → 5.7, then 5.7 → 5.8 and so on until 5.9 ->5.10 ?

Or can I upgrade directly from 5.6.x to 5.10.x?

What procedure do you recommend for a safe upgrade?

Thx !!

It is recommended to got to the latest minor versions

Or can I upgrade directly from 5.6.x to 5.10.x?

It is possible.

In any way I’d recommend to create a fresh snapshot/backup before upgrading your cluster.
