Am wondering if anyone has ever tried migrating a present RAC environment (2 node cluster using ASM accessing a SAN for the data and flash). I know I can convert the physicals but all documentation I have found on disk sharing points to creating the disks and doing the multi-writer option. This is not possible when the added disk is using a Raw Device Mapping which is my only option when presenting the LUNS to the host server. This is an ora10g and ESXi 5.1.
I think install a new RAC in vmware and migrate data from old db use export/import or sqlload is a better and safer choice .
