Network Operations
WordPress moves your entire site (database, files, settings) to new hosting. Success requires careful planning and verification to avoid broken links, database corruption, or lost functionality.
Migration methods
- Plugin: All-in-one tools (Duplicator, WP Migrate DB) - easiest
- Manual: Backup + restore via FTP + database import - most control
- Hosting provider: Built-in tools (UnderHost support)
Plugin (easiest)
- Install Duplicator plugin
- Create installer package
- Download package files
- Upload to new host
- Run installer (handles database, URLs, everything)
Manual migration
- Backup database:
mysqldump -u user -p db > backup.sql - Download all files via FTP
- Create database on new host
- Upload files to new host
- Import database:
mysql -u user -p db < backup.sql
Update URLs
After update WordPress to use new domain:
- Settings → General: Update Site URL and WordPress URL
- If database : Run search/replace (WP-CLI):
wp search-replace old.com new.com
Verification checklist
- ☐ Front page loads correctly
- ☐ Posts/pages display properly
- ☐ Links work (internal and external)
- ☐ Database queries work (no white screen)
- ☐ Uploads folder accessible

Test on new host before switching DNS
Point your domain to new host via /etc/hosts first. Test everything works before updating DNS.
