Read only Tablespaces after upgrade
Afternoon!
We have a 4TB database with about 3.4 TB of data in Read-only tablespaces. We are going to be upgrading from 11.2.0.3 to 12c and I was wondering if after the upgrade do I need to put these tablespaces back into read/write and do a fresh backup or anything to update the headers or is that not necessary?
Thanks for any responses!
