Migration Instruction for "VPN: IPsec: Tunnel Settings [legacy]"

[tuaris]

As per the page at https://docs.opnsense.org/manual/vpnet.html#migrating-from-tunnels-to-connections

1. Does it work exactly the same or will I see any loss/difference in functionality?
2. Do I need to change anything on the remote end?
3. If the IPSec tunnel is between two OPNSense gateways, what must I do to ensure I do not lose connectivity?

Worked as documented for me. You can compare the strongswan configuration files before and after.
