Upgrade Rancehr From 2.2.5 to 2.38


I follow this steps (i need to upgrade also cert-manager):


In this link there is this command:

helm delete rancher -n cattle-system

But if we use this command, we’ll lose all the configuration and cluster that are present now in the Rancher 2.2.5.

In the first command of guide to upgrade rancher:

helm get values rancher

and we have as output only the hostname.

If i delete the rancher chart and re-install the new one, will we lose all the configuration for all cluster that we have configured in Rancher?

Is it possibile to bkp from 2.2.5 and import the backup to the 2.3.8 backup?
