I am setting up a new 11.2 environment (3 primary servers in single management zone) to replace an older 11.1 environment (3 management zones, each with own server).

One major step is to reimage all the PC's (1200-2000) with new settings. These PC's have been imaged in the old system and need image safe data cleared as part of the new imaging process.

What is the best (automated) way to reimage all these systems and clear the image safe data at the same time? Is this a matter of applying a preboot imaging script (single command to clear image safe data) and linking to the image being called?
