Nginx Proxy Manager LXC update procedure?

[vsc55]

Hi,
I currently have Nginx Proxy Manager running on a docker but I want to migrate it to an LXC.
I have Nginx Proxy Manager configured using the json file as a database.
Before making the change from Docker to LXC, I would like to know what the procedure is to update LXC to the latest version of Nginx Proxy Manager without losing the database.
Does the script itself create a new LXC each time? Does the script update the LXC that is created without losing the settings? Do I have to do any manual file export procedure?
Thanks.

Type the command update in the LXC console
