Changes

The database is migrated from one platform to another using Transportable Database (By RMAN Convert Command), e.g:

Step 1: Shutdown the source DB, and copy the datafiles to the target node nfs mount point.

Step 2: In Target Node,prepare the DB and startup the Database in nomount stage

Step 3: Perform the Conversion process using RMAN Convert command in Target Node

You may get ORA-07445 errors while you open the database in the Target Database (Step 5).
