the story is: we need to move to higher hardware version of network DLP.
the question is how to migrate all the configurations, policies...etc. to the new hardware?? is it a regular bcakup and restore
The backup is performed on the manager. With 9.3 and above, this backup can be restored to any DLP platform (1650 / 3650 / 4400 / 5500 / VM). I recommend that you are running at least 9.3.2.
The backup and restore process can be found starting on page 335 of The NDLP Product Guide PD24986.
