Hi All,
We are 'inheriting' an Oracle 11G RAC cluster from another company and I am looking for a way to migrate with minimal amount of downtime. Our team does not have extensive RAC experience, nor Oracle database admin for that matter.
We plan to test the migration by cloning the environment a couple weeks before and just seeing if everything comes up ok.
Question is, what is the best way to migrate this RAC cluster and it's data to a new data center? Reinstalling the OS (Linux) and recreating the RAC cluster is not an option I want to consider.
For example, in SQL server land, we can use log shipping or replication to keep a copy of the database in the new data center as close (data-wise) to the live database as possible. Then on cutover date, we stop the live instance, run the last log restore or whatever, and bring up the databases on the new data center.
Thanks in advance.
