About this plugin
Onecraft Site Migration moves a single WordPress website from one place to another.
On the source site you export everything into one downloadable package; on the
destination you upload that package and import it. The URLs are rewritten to the
new domain automatically.
It is built to be reliable on ordinary shared hosting, where a single PHP
request cannot do all the work:
- Runs in small, resumable steps. Long jobs are split into bounded “ticks”
driven from your browser, so they never rely on one giant request.
- Streams, never loads everything into memory. Files and database tables are
processed in chunks, so a large file or table will not exhaust memory.
- Serialization-safe search & replace. When the domain changes, PHP-serialized
option and meta values are rewritten correctly (string lengths recomputed).
- Validates before it touches the destination. The uploaded package’s
checksums are verified before anything is imported.
- Automatic rollback. The destination database is backed up before import; if
the database import fails, it is restored automatically.
This is an original implementation. It does not use or copy any other plugin’s
archive format, code, or interface.
What is migrated
- All of wp-content — themes, plugins, and uploaded media.
- The database — posts, pages, settings, users, and so on.
What is not migrated
- WordPress core files ( wp-admin / wp-includes ) and wp-config.php. The
destination must already be a working WordPress install; the destination keeps
its own core and database connection settings.
