We are planing to migrate oracle 11g database from Aix platform to the oracle linux (Exadata) . We can use oracle datapump method but it can be slow for large database. Customer want to migrate database within minimum downtime . However at the moment we have decided to use transportable tablespace method.
Following systems are going to be migrated:
Production
oracle db version : 11.2.0.1
Operating System : AIX
New Server
oracle version : 11.2.0.4
Operating System : Oracle Lunux 6
Database size : 1TB
1) What is the best method we can propose for such a environment ?
2) How can we minimize the cutover time ?
