I have a huge database size needs to be migrated and upgraded across different platforms, I done the initial migration and the upgrade test on the new server successfully to the latest release (126.96.36.199) and the new Oracle server is ready now for the cutover.
Meantime, data files needs to be taken and migrated to the new server again since the tested migrated data is aged out, what's the best way to minimize the the time requires during the process of converting and transporting data from old platform to the new platform. I used RMAN convert and it took me long time though. My source db server is windows, destination is Linux.
Also, I am trying to figure out the way of identifying the schemas which have been affected after a particular timestamp (last convert), so then I can use pump or dump backup to export only the data which was updated after last data convert?
