oracle RAC with ASM upgrade from 10g to 11g
I am going to start oracle upgrade from 10G to 11g.Could anyone please share the document if there is any proven approach with less downtime.
2-Node RAC env ( all the crs, rdbms.asm using local homes)
CRS - 10.2.0.5
ASM HOME - 10.2.0.5
RDBMS Home - 10.2.0.5
I am planning to upgrade the env to 11.2.0.4 version.
Thanks,
Kiran
