I have 2 servers, on each of them an existing single instance (same version)
I want to install GI and change it to a cluster server.
Two Main questions:
1. Is it possible to install Grid infrastructure on those existing servers while the instances still alive (after of course setting interconnect, ASM shared storage and all other settings)
2. After that adding the existing instances as resources to the cluster (and adding another instance for each) - probably after migrating to ASM so that the storage will be shared as well.
Thanks,
Lior
