Hi all We have a deployment of ISPConfig on one server, business (thankfully) grows and now we need to spread load on more servers and in between upgrade to a newer Debian release (running Stretch with NginX and multiple PHP 5.6 to 7.4. - What would be the best procedure? - Is is good idea to take the opportunity to upgrade Debian to Buster or even Bullseye? - can we spread web load on many servers but providing only one public IP? - Can we move a client from one web node to another without breaking things? Thanks!
