Hello,
I have succesfully added my Hosts to the new vCenter. The procedure was:
- Disassociate each Host from the old vCenter
- Create a cluster in the new vCenter with HA disabled and EVC mode equal to the old one
- Connect each host directly into the new cluster. If vCenter claim about the EVC mode, just add the host at the Data Center level and when connected move it to the cluster.
- Enable and configure again the HA in the new cluster
Thank you all for the help!
Andrea
