docs and procs for rman incremental backup method to complete Large DB migration from 10g to 12c

in Database Backup and Recovery (MOSC) 7 commentsAnswered


We successfully completed a test migration of 5TB of data from Oracle 10g to Oracle 12c using Transportable Tablespace method with expdp/impdp.

However, for testing we had the source 10g Tablespaces in Read Only mode for 5 days while the associated datafiles were copied using the linux rsync command. There were network interruptions that caused rsync to stop and resume .

The problem we face is that we have to migrate the production data of 10 TB from Oracle 10g to Oracle 12c using Transportable Tablespace method with expdp/impdp. We cannot afford any downtime because this is a critical Customs application that will impact the country's economy.

Howdy, Stranger!
