What to do with .wpress file?

.wpress is essentially the WordPress site exported so in order to use it you can this this tool to convert the file to zip format but you’ll have to do a manual WordPress import using WP-CLI or manually creating the database fixing links.

Another option to use this file is to install a fresh WordPress and All-In-One-Migration plugin. Then import that file and the newly set up WordPress site will be replaced with the site that was packaged into the wpress file.
The import has to happen from within All-In-One-Migration import screen and not Tools > Import because it’s not an in the WordPress XML/RSS format. You will most likely get an error: Make sure you are using a valid WordPress export file in XML or Zip format

Again make sure you upload (import) the .wpress file into a fresh WordPress installation because it WILL override the site.

What does .wpress file contain?

It seems All in One Migration plugin packages only the wp-content folder to save space.

In the root folder there are

  • database.sql -> this the database file exported in SQL format BUT instead of the actual site prefix it has SERVMASK_PREFIX_ prefix. Therefore you need to replace that with whatever you like if you’re doing a manual import via wp-cli
  • package.json – This file contains lots of site info and a base64 serialized version of the .htaccess file. Quite clever actually.
  • You need to check the WordPress version from the package.json to install that specific version.
