Thanks for the replies. Here's how my upgrade process went.
- Upgraded all licenses to NGX in the UserCenter.
- Used the NGX upgrade_export utility to export all rules and objects from the existing SmartCenter server.
- Built a fresh install (on a different machine) of SecurePlatform R60 for my new SmartCenter Server, making sure to apply all hotfixes.
- Used the NGX upgrade_import utility to import all rules and objects to the new SmartCenter server.
Worked flawless.
- Built a fresh install (on a different machine) of SecurePlatform R60 for my new gateway, making sure to apply all hotfixes.
- Re-established SIC between the SmartCenter server and the gateway.
- Made certain topology was correct, by getting topology from new gateway.
- Attached licenses, got gateway data, etc... in SmartUpdate.
- Saved and installed policy on the new gateway successfully.

Once again everything worked flawless (in my mock network environment). When I put the new gateway in service though, it runs fine for a period of about 3-6 hours when it finally just becomes unresponsive.

Like I mentioned before, since then I have changed the gc_thresh3 and gc_stale_time settings because of the "neighbor table overflow" message that I was receiving.
I've used ethtool to ensure that I my nics are running at the same speed as the switches I'm connecting through (100mb/full), so as not to confuse the nic any more by trying to autonegotiate the speed. I have started a new ticket with Checkpoint and am waiting for a response back. Maybe still an issue with the nic. Stay tuned for more. Thanks.
