Switch from DuckDNS to Nabu Casa?

Hello,

At the start i don’t want to pay the subscription to Nabu Casa. Now, after many month of DuckDNS, port forwarding and DIY google integration i decide to switch. My Helix Fi router send me security alert every day and in th log of my router they are a lot of attack on my Port forwarding so i want to secure a litle bit more.
Now, i can’t acces HA localy. What are the step i need to do in order? Desable port forwarding or delete my DNS? I will still be able to log to HA via Nabu Casa.
When in the process I can get back my local connection via http://IPadress:8123/ ?

Thank you for your time and aexcuse my English.
