At the moment the staging area is useless for Magento installations (or any other store installtions). The whole point of a staging area is so you can work on the site without risk breaking the live site and then you can push your changes live.
If you try this on a Magento Store (or WordPress if you use WooCommerce) you’re not able to do this as the database is over-written with the staging site which has out of date orders and customer files, which of course leads to missing orders.
It seems like a simple fix, give us the option to exclude database tables from being migrated, sure I select to not migrate the database all together but on a database driven site how useful is this?? Most of the changes we make are within the Database.
