Error After Cloning Networks

[Riser]

After cloning a network in my organization, I get the below error when enabling a site-to-site VPN on the new cloned network.

Could this be happening because another network in my organization uses the same subnets?

Once I delete the other/older network or remove appliances from the network, will it allow me to save the site-to-site VPN settings in this new cloned network?
I want to keep everything as it was in the original network.

Yes, you already have those subnets active on another network connected over S2S VPN (assumedly the one you cloned from).

You need to either:

1. delete the old network

2. Disable S2S VPN on the old network

3. Change the subnets on either the old or new network so they no longer overlap
