WordPress migrations usually fail in predictable ways. Knowing the common mistakes makes them easier to avoid.
Forgetting the Database
WordPress content and settings live in the database. Copying files alone is not a migration.
Breaking Serialized Data
Use WordPress-aware tools when replacing URLs in the database. Basic text replacement can break serialized values.
Changing DNS Too Early
Test the new copy before switching traffic. Keep the old hosting available until the new site is confirmed working.
Ignoring Email
Website DNS changes can accidentally affect mail. Preserve MX and authentication records.
A careful migration is a sequence, not a rushed file upload.
