Looking for suggestions to Migrate & upgrade 80+ TB of database on Solaris Sparc to Linux 64 bit. Currently backup takes about 4 days to complete. Assume that we can get downtime of 24 hrs to do platform migration.
Option 1:
Looking Golden Gate option, technically it should be possible but I need to transfer full database/all schema etc. In Golden Gate, is there option to do full database or need to configure each schema extract/replicate etc. Also I think 80+TB initial load would be tricky. Any suggestions .
Option 2:
Migration of An ASM Diskgroup Across OS Platform (Doc ID 1566352.1)
Looks like this option is not supported. Is it possible to take snapshot of ASM devices ( storage side) , kind of mirror copy and present on other side ( Assume that initially we are running same version of ASM & database but different endian format) so need to covert al datafiles using rman. I know that this option is not supported so may not be worth to pursue
We can do one process at a time e.g. do only platform migration first and then do upgrade later, if that makes thing easier.
So looking for suggestions and recommendations.
Thanks a lot.
