Migrating 100F HA cluster to two new units 120G

I have to migrate configuration from two Fortigate 100F units in HA (active/passive), currently in production, to two new Fortigate 120G already purchased.

In the configuration of the 100F units there are:

15 IPSEC lan2lan vpn tunnel

many users (local) IPSEC dialup vpn (non-SSL)

By loading the configuration file of the 100F into the 120G (after pre-configuring them), the shared secrets of the LAN2LAN VPNs, the passwords of dialup VPN users will be preserved or will they have to be reinserted again?

Thanks for support.
