Split a stretched cluster into two "2 node clusters"

[Convergo]

What would be the correct steps (high level) to split a stretched cluster with production vms into two seperate 2-node clusters, and is this supported ?

Hi @Convergo 

In my opinion, it is possible to split a stretched cluster into two 2-node clusters but it's essential to follow proper steps to avoid data loss or service disruption.

Before splitting a stretched cluster, ensure data across the stretched cluster is fully synchronized which minimizes data consistency.
You may migrate data from the stretched cluster using live migration, backups, and restores.

I've pulled a few links that could be helpful:

If you have further doubts regarding this, I would recommend you to contact HPE support team for more assistance.

Hope this helps.
