I have a running nextcloud aio installation on Ubuntu 22.04 which is available under a specific subdomain (followed the instructions under GitHub - nextcloud/all-in-one: Nextcloud AIO stands for Nextcloud All In One and provides easy deployment and maintenance with most features included in this one Nextcloud instance.).
I missed to consider a NPM which I now need for additional services. I added jc21/nginx-proxy-manager in docker on a different host to my installation and tested it. I am able to address servers in my lan.
I would now ike to change the apache port as described in all-in-one/reverse-proxy.md at main · nextcloud/all-in-one · GitHub
How can I do this without endangering my current installation? (backup available)
Should I run the startup command with added apache port again (i.e. -e APACHE_PORT=11000 ) and than import my backup or is there an easier way to do this?
