+
+## On the new server:
+
+1. Run the install script first (without creating admin user)
+2. Stop all Mastodon services:
+   ```
+   systemctl stop mastodon-web mastodon-sidekiq mastodon-streaming
+   ```
+
+3. Restore the database:
+   ```
+   sudo -u postgres dropdb mastodon_production
+   sudo -u postgres createdb -O mastodon mastodon_production
+   sudo -u postgres pg_restore -d mastodon_production database.dump
+   ```
+
+4. Restore .env.production:
+   ```
+   cp .env.production /home/mastodon/live/.env.production
+   chown mastodon:mastodon /home/mastodon/live/.env.production
+   chmod 600 /home/mastodon/live/.env.production
+   ```
+
+5. Restore user uploads:
+   ```
+   cd /home/mastodon/live/public
+   tar -xzf /path/to/backup/system.tar.gz
+   chown -R mastodon:mastodon system
+   ```
+
+6. Update LOCAL_DOMAIN in .env.production if domain changed
+
+7. Run migrations (in case of version upgrade):
+   ```
+   sudo -u mastodon bash -lc 'cd ~/live && RAILS_ENV=production bundle exec rails db:migrate'
+   ```
+
+8. Recompile assets:
+   ```
+   sudo -u mastodon bash -lc 'cd ~/live && RAILS_ENV=production bundle exec rails assets:precompile'
+   ```
+
+9. Fix SELinux contexts:
+   ```
+   chcon -R -t httpd_sys_content_t /home/mastodon/live/public
+   ```
+
+10. Start services:
+    ```
+    systemctl start mastodon-web mastodon-sidekiq mastodon-streaming
+    ```
