Database migration across platforms and conversion of single instance to RAC

Working in a huge RAC environment, each passing day is a learning day for me. After setting up 4 node RAC on HP UX Itanium 2 Severs, the subsequent task/challenge is to migrate single instance databases (around 16) from AIX OS to HP OS and plus converting single instance to RAC.

I have started this task on a low confidence note, I would be lying if I say I was very much confident. However, as thing progress, my confidence level went high and at the end I have successfully migrated a database (single instance) from AIX OS to HP OS and then converted the single instance database to RAC database.

To give you a rough idea what I have done:

Converted database from AIX to HP using RMAN.
On HP, then, converted this databases from single-instance to RAC database. There are few ways using which you can achieve this. However, I have opted the DBCA option to execute the task.

Next step is to migrate and convert the rest of the databases using the same method.

Happy reading,
