mp-wp_genesis 172 * Upgrade the core of WordPress.
mp-wp_genesis 173 *
mp-wp_genesis 174 * This will create a .maintenance file at the base of the WordPress directory
mp-wp_genesis 175 * to ensure that people can not access the web site, when the files are being
mp-wp_genesis 176 * copied to their locations.
mp-wp_genesis 177 *
mp-wp_genesis 178 * The files in the {@link $_old_files} list will be removed and the new files
mp-wp_genesis 179 * copied from the zip file after the database is upgraded.
mp-wp_genesis 180 *
mp-wp_genesis 181 * The steps for the upgrader for after the new release is downloaded and
mp-wp_genesis 182 * unzipped is:
mp-wp_genesis 183 * 1. Test unzipped location for select files to ensure that unzipped worked.
mp-wp_genesis 184 * 2. Create the .maintenance file in current WordPress base.
mp-wp_genesis 185 * 3. Copy new WordPress directory over old WordPress files.
mp-wp_genesis 186 * 4. Upgrade WordPress to new version.
mp-wp_genesis 187 * 5. Delete new WordPress directory path.
mp-wp_genesis 188 * 6. Delete .maintenance file.
mp-wp_genesis 189 * 7. Remove old files.
mp-wp_genesis 190 * 8. Delete 'update_core' option.
mp-wp_genesis 191 *
mp-wp_genesis 192 * There are several areas of failure. For instance if PHP times out before step
mp-wp_genesis 193 * 6, then you will not be able to access any portion of your site. Also, since
mp-wp_genesis 194 * the upgrade will not continue where it left off, you will not be able to
mp-wp_genesis 195 * automatically remove old files and remove the 'update_core' option. This
mp-wp_genesis 196 * isn't that bad.
mp-wp_genesis 197 *
mp-wp_genesis 198 * If the copy of the new WordPress over the old fails, then the worse is that
mp-wp_genesis 199 * the new WordPress directory will remain.
mp-wp_genesis 200 *
mp-wp_genesis 201 * If it is assumed that every file will be copied over, including plugins and
mp-wp_genesis 202 * themes, then if you edit the default theme, you should rename it, so that
mp-wp_genesis 203 * your changes remain.
mp-wp_genesis 204 *
mp-wp_genesis 205 * @since 2.7.0
mp-wp_genesis 206 *
mp-wp_genesis 207 * @param string $from New release unzipped path.
mp-wp_genesis 208 * @param string $to Path to old WordPress installation.
mp-wp_genesis 209 * @return WP_Error|null WP_Error on failure, null on success.
