Change website directory

hi, i have 50 gb ssd as mail directory and 150gb as attachment. My all websites are hosted in the 50gb disk . i want to change directory of few websites to 150gb disk . so i transferred the files and changed apache config virtual host and nginx host file config

files i changed are

nginx host file and ssl file  and apache host file ( changed root directory to- /mnt/data/vajiramandravi.tk)

# Virtual host file starts here

server {
listen 10.8.98.197:80;
access_log /var/log/nginx/access.vajiramandravi.tk.log;
error_log /var/log/nginx/error.vajiramandravi.tk.log;
