Ipsec Encryption Domain

Hi.

I have two Routers,

The first is a x86 with Routeros Licence L6, the seconds is a CCR1016-12g ROS 6.10.

I´m upgrading the hardware so CCR1016 is my new router. I have an IPSEC vpn configured exactly on both routers but when i have installed the new router IPSEC tunnel is up but domain encryption can´t see in remote sites.

The configuration was migrated with the previous backup router and the remote site is a Paloalto PA5050 version is PAN 6.0.4.

I think is a version problem..

Can anyone help me?
