Migration

When migrating a WordPress site from one server to another, consider the following steps:

  1. Backup Files and Database: Ensure you have a complete backup of your WordPress files and database.
    • The files to back up include the entire WordPress directory, typically located at /var/www/html/your-site.
    • The database can be backed up using tools like mysqldump
mysqldump -u username -p database_name > backup.sql
  1. Transfer Files: Use rsync or scp to transfer the WordPress files to the new server.
rsync -avz /path/to/wordpress/ user@newserver:/path/to/destination/
  1. Import Database: On the new server, create a new database and import the backup.
mysql -u username -p new_database_name < backup.sql

  1. Update wp-config.php: Modify the wp-config.php file on the new server to reflect the new database credentials.

  2. Update Site URL: If the domain name has changed, update the site URL in the database. You can do this using wp-cli:

# Migrate http to https
docker run --rm --volumes-from wp-container --network container:wp-container wordpress:cli search-replace 'http://original.domain' 'https://new.domain'
# Migrate https to https
docker run --rm --volumes-from wp-container --network container:wp-container wordpress:cli search-replace 'https://original.domain' 'https://new.domain'
# Migrate any remaining references
docker run --rm --volumes-from wp-container --network container:wp-container wordpress:cli search-replace 'original.domain' 'new.domain'
# Flush cache
docker run --rm --volumes-from wp-container --network container:wp-container wordpress:cli cache flush

Remember to recreate any cache of the extensions you are using.
