R55 to R62 upgrade

[sdrodgers]

Upgraded management server with a new server and import from the R55 export.

Everything looks good but when I pushed policy from R62 management to a R55 nokia cluster the push to one cluster failed, tried it a couple of times and finally was able to push policy. But now the cpu is running at 98 to 100%.
When I connect the old R55 management server back and push everything goes back to normal.
Why pushing from a R62 management server to a R55 gateway cluster did my gateway cpu spike up. Network slowed down and was receiving reject packets that should not have been rejected.

Update

After further investigation the cause of High CPU utilization is Smart Defense from R62. Smart Defense is causing high CPU utilization on my R55 firewalls. Once I disable Smart Defense and push the cpu utilization drops.
