Before, I wrote a post about how to install Vaultwarden. Today, I migrate it to a new server and let me tell you how to do it.

1 2	tar -czvf vw-data.tar.gz /vw-data/ scp vw-data.tar.gz root@new.server:~

sudo certbot certonly --nginx -d vaultwarden.new.server
ln -s /etc/nginx/sites-available/vaultwarden.new.server /etc/nginx/sites-enabled/
vim /etc/nginx/sites-available/vaultwarden.new.server

server {
    listen 80;
    listen [::]:80;
    server_name vaultwarden.new.server;

    # Redirect all HTTP requests to HTTPS
    return 301 https://$server_name$request_uri;
}
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    ssl_certificate /etc/letsencrypt/live/vaultwarden.new.server/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/vaultwarden.new.server/privkey.pem;
    server_name vaultwarden.new.server;
    client_max_body_size 525M;
    location / {
    proxy_set_header Upgrade $http_upgrade;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_buffers 8 16k;
    proxy_buffer_size 32k;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_pass http://localhost:3000/;
    }
}

service nginx restart
docker run -d --name vaultwarden -v /vw-data/:/data/ --restart unless-stopped -p 3000:80 -e DOMAIN=https://your_domain -e SIGNUPS_ALLOWED=false -e SMTP_HOST=your_mail_server_domain -e SMTP_FROM=your_mail_address -e SMTP_PORT=587 -e SMTP_SECURITY=starttls -e SMTP_USERNAME=your_mail_username -e SMTP_PASSWORD=your_mail_password vaultwarden/server:latest
# if your SMTP_PORT is 587 or 25 with ssl, set SMTP_SECURITY=starttls, if your SMTP_PORT is 465, set SMTP_SECURITY=force_tls, it your SMTP_PORT is 25 without ssl, set SMTP_SECURITY=off. I learned these today. Last time it is very luck for me. This time I changed SMTP_PORT without chaning STMP_SECURITY, it would not work for me.
docker stop vaultwarden
rm -rf /vw-data/
tar -xzvf vw-data.tar.gz
mv vw-data/ /
docker start vaultwarden

All done, you can check if all your passwords migrate successfully.
