I know, its a long jump.
Anything you learned along the way that jumped out at you?

Firstly, you cannot upgrade directly from v9.x to v12.x see http://seer.entsupport.symantec.com/docs/289451.htm
Also, be sure that you have v12 serials for any options that you are licensed for with v9
Other than that, the upgrade to v10 or v11 and then to v12.x should be no problem
