Hi,

I am working on RAC migration of two interlinked PROD databases, one is ERP and the other is core database. ERP is on 10g and core database is on 11g. Both needs to be migrated to RAC. The rac instances of both the databases resides on same servers. Now Do I need to install both 10g crs and 11g crs? Can we run two versions of CRS on the same servers to run different databases? Or Can I run both 10g and 11g instances using single 11g crs software? I tried to get the information over the internet but I could not get any. Can someone thro' some light please.

Thanks,
Chaitanya

You can only run one version of CRS and in your case, you would use the 11g version of CRS.
