Hi,

In general the same approach is probably the way to go - however if you are going to be doing significant amounts of migration work it is worth getting the planning right.

Much of the configuration is dependent on the way that the storage is configured and whether you are using Oracle ASM or not, ASM is worth having if you have significant I/O on the database but with a high performance backend the additional managemnt overhead may not be worth while.

If the storage is tiered and you think it will deal efficiently with the I/O, I'd go for the presentation of a single LUN - this makes future migrations, DR and failover really simple. The drawback would be if you have to run fsck or some other tool, it has to do the whole LUN not just a couple of small partitions or LUN's. Where you have SAN replication the single LUN approach makes life easy, you won't miss something if it's all in one place.

If performance is key, then you may want to take advantage of the tiering in a different way. There is much to consider when doing migration work like this, it is well worth while runing a proof of concept (if you can) just to check things out.
