WAN Failover in 5.2

I recently upgraded our 90D from 5.0.13 to 5.2.7.  We have dual WAN links with Weighted Load Balance and failover.  I noticed that the process is completely different for 5.2 than it was for 5.0.  Do I have to rebuild all my static routes and policies to create a new VIP, or did my config carry over to the new FW.  I really don't look forward to spending my Sunday rebuilding everything.j

Thanks.
