Move from CLI installed RKE to Helm install

I am currently using a RKE install of Rancher which I installed using the RKE binary.
I want to upgrade my install to Rancher v2.5 and wonder if I can do that by running a Helm install from within Rancher itself or do I need to upgrade it from the binary since that is how the original install was done.

Just afraid that I will install the new version on top of the other without it being an actual upgrade…
