Hybrid node SOs and how to migrate from Windows to Linux

Hello,

we have a client that runs a 6 node cluster on VMs that runs Windows Server. We have the plan to migrate this cluster to Linux. I was wondering what the easiest approach would be, with zero downtime.

My plan is to bring the Linux VMs up, maybe one at a time, include them in the cluster, migrate shards and turn the windows server down... in the and I would have all my cluster in a Linux environment.

I never thought about this, but I think it is ok to have hybrid node SOs in a cluster? Right?

I also found this question on Stack Overflow in which some approaches are suggested.

What do you think?

Thank you for your thoughts on this

That'll work fine. When you're working on a data level, Elasticsearch doesn't care about what OS it's running on.
