How to migrate Cluster mode to 7 mode



we just purchased a new HA FAS8020 controllers, we have the following issues:

1. we didn't purchase new disk shelves, therefore we are going to use our existing DS4243,DS4246 SATA shelves. We need to take data from existing storage, but unfortunately it was destoryed in flood. New storage come with daa ontap 8.3.x. So we are plan to migrate from cluster mode to 7 mode and reterive data from 7 mode connect with two disk shelves.
2. So I am not aware of migrate from  Cluster mode enviornment to 7-Mode enviornment. If any one know can you share the KB article or document.
