Up sizing array how to copy folders and data and retain permissions

[allpdoff]

Hello,
I am replacing the hard drives in an array to increase capacity. I need to copy the data to a temp location than back again with out loosing complex folder permissions for live websites.

Can anyone offer me a safe method to move the files back and forth about 70 gigs of data.

Robocopy with the /sec option.
