My way of dealing with this is to ensure everything is provisioned and managed via gitops. I have a homelab repo with a combination of Ansible, Terraform (Tofu), and FluxCD. I don't have to remember how to do anything manually, except for provisioning a new bare metal machine (I have a readme file and a couple of scripts for that).
I accidentally gave myself the opportunity to test out my automations when I decided I wanted to rename my k8s nodes (FQDN rather than just hostname). When I did that, everything broke, and I decided it would be easier to simply re-provision than to troubleshoot. I was up and running with completely rebuilt nodes in around an hour.
