VPN not establishing because remote subnet the same.

I have a FortiGate firewall and its acting as a HQ. I have couple of branches and the connection is great through VPN.
Now I want to add a new branch. But the remote subnet is overlapping, that is why it’s not connecting. I already have a branch with that subnet. For example 192.168.0.0.

When I change the remote subnet to 192.168.13.0, i do get a VPN connection.

I can’t change the IP subnet of that branch. Is it possible to change it in the firewall of the FG?

Thanks

    Thanks for the documentation. I will do my best and configure it.
    If you or others are happy to assist me with it. I would greatly appreciate it.

    (I do have support on my fortigate). I do like the forum interaction and the people are skilled.
