Now, since you have experience with actually doing the migration, let me know if this would work (we will of course try it out soon too):This can be achieved with a minimal downtime, by shutting down the database and snapping LUNs which contain the database. That is equivalent to a cold backup, only two orders of magnitude faster. After the snapshot, the database can be restarted.
1. Copy the 'datafile copies' from source to destination staging area
2. Run the 'convert from platform' RMAN command, to convert those datafile copies so they land in the real datafile locations
3. Copy the subsequent 'Incrementals' from source to destination area
4. Convert the Incrementals on destination to apply to real datafile (from Step 2).Yes it does. However, few steps have been left out. I am not sure whether AIX db is single instance or RAC, but you will need to add the undo tablespace for each instance and create as many redo threads as you have instances. Single-instance database has only a single active redo thread. You will also need to add instances to OCR by using srvctl add instance. Only when that is done, you will have a full fledged RAC database on Linux.
5. Repeat 3 & 4, until you're almost caught up, and do a final 3 & 4 with source tablespaces being read-only.
Does this make sense? Pls share your thoughts.
