Shipper Pro is a premium WordPress plugin developed and maintained by WPMU DEV. It is designed to simplify the process of migrating a WordPress website from one server or host to another.

The plugin offers two migration methods: API migration and Package migration.

The API method uses a secure API to transfer data between the source and destination servers, while the Package method compresses the website files and database into a ZIP package, which can then be uploaded to the destination server.

The plugin also includes several advanced tools, such as pre-migration safety checks, large file detection, and the ability to find and replace site links.

It also features a migration-safe mode, which can be enabled to increase the chances of a successful migration.

Shipper Pro is multisite-compatible and can migrate whole networks or individual subsites to single sites. It also includes features for excluding certain files, folders, and databases from the migration process.

Additionally, Shipper Pro includes a migration wizard to guide you through the migration process step-by-step, and email notifications are sent when the migration is complete.

The plugin also includes failed migration troubleshooting to help you resolve any issues that may arise during the migration process.

Migration logs are available for review and analysis, and you can protect your migrations with passwords.

Overall, Shipper Pro is a comprehensive migration plugin that provides website owners with a simple and efficient way to migrate their WordPress sites to new servers or hosts.
