Hi everybody, I'm migrating my clients infra to a new datacenter (leader node + central worker group and multiple worker nodes).
What is in your opinion the best way, to migrate the LN?
It will be a new VM with new ip/dns

Migration Strategy Needed For Leader Node To New VM With New IP/DNS
Best answer by Jon Rust
Leader:
- update the existing leader to latest
- install a fresh leader package and set-up the boot start config
- archive/restore the previous install on top of this new install
- validate new leader is running and no firewalls, proxies, etc are in the way
- There is no benefit to moving installs from old workers -- start fresh
- Follow normal install procedure for workers
- Ensure your load balancers, firewalls, etc are pointing to the new worker nodes

Thanks Jon. The current leader node uses gitops. Is it possible to connect the new leader and restore from the repo?
i believe yes. Not sure of the specifics tho
