So I'm looking to replace some old MongoDB servers, these are VMs that are manually managed, and they need a fresh ground-up rebuild. They're in multi-node clusters (3 nodes) -- I've never tried to do a per-node replacement/replication on them before. Is there an easy way to basically just like... bring a node into the cluster, then take a node offline and do that one at a time for all 3? It this a huge pain and it'll be easier to just stand up a whole new cluster and replicate? I can deploy same-version then upgrade the new cluster so that's not necessarily a problem.
Thoughts?
