How to merge two clusters

[OPTEAMAPROJET]

Hello,

I currently have two datacenters with one 2-nodes cluster in each site. I will move the two clusters on the same site and would like to create a 4-nodes clusters.

Does anyone knows how to "merge" the two clusters without loosing datas ?

Thanks for your help,

Julien

As far as I know this is not possible but I'd love to be proven wrong.

you cannot merge but you can snapmirror all data from one cluster to another (if you have enough space) and then destroy one cluster and join the nodes to the other cluster (making it a 4 node cluster)
