if you plan to use the NetApp snapmaanger for SQL and Oracle tools, then you could use these to do the migration.
if you present the new NetApp luns up to the servers, install the appropraite software, the config wizards of both tools will migrate your databases for you.
however it is disruptive (certianly for SQL) with the databases been manually moved to the luns, so offlined and copied.
but they are a good solid migration method, making all the appropriate DB changes that you need.
