WordPress – Exporting and Importing Database
Helpful resources (specifically to copy/move an existing site from an old domain name to a new one, which includes needing to copy/move the WP database, since the old site will still exist) for exporting and importing database onto new server:
- WordPress Codex
- Exporting and Importing WordPress
- WP Migrate DB (Migrate to a different domain and still maintain serialized data. Find and replace URLs and file paths.)
