From oblivion to zen - moving from old server to new one

I need to change my hostname, cause I choosed stupid one. My forum is installed and working good.
Is this all steps and in right order?
Current hostname is "hostname"
uname -n show:

Code:

hostname.pijanitvor.com

I need to change that hostname to tvor-ocean

Steps:
command

Code:

hostnamectl set-hostname tvor-ocean.pijanitvor.com

then edit /etc/hosts to be like that

Code:

127.0.0.1 localhost.localdomain localhost
127.0.0.1 localhost4.localdomain4 localhost4
46.101.130.248 tvor-ocean.pijanitvor.com hostname

then restart network service

Code:

service network restart

And last step after restarting network service is editing server's default hostname's Nginx vhost configuration file, and change old server_name hostname.pijanitvor.com to new one tvor-ocean.pijanitvor.com.

Should it be from this:

Code:

server {
#         listen   80;
            listen   80 default_server backlog=2048 reuseport;
            server_name hostname.pijanitvor.com;
            root   html;

to this:

Code:

server {
#         listen   80;
            listen   80 default_server backlog=2048 reuseport;
            server_name tvor-ocean.pijanitvor.com;
            root   html;

Anything else before this steps or after this steps I should do?
Stop some services before do that? Restart nginx or something else?
Close forum?
