Becarful : table names have been changed. Every table is now prefixed by default with "aropixel_". You can override this settings by copying mapping files in your project.
Automatic generation migrations will generate DROP and CREATE TABLE lines.
In order to avoid data loss, you should modify your generated migration files whith following lines:
* RENAME TABLE post TO aropixel_post
* RENAME TABLE post_image TO aropixel_post_image
* RENAME TABLE post_image_crop TO aropixel_post_image_crop
* RENAME TABLE post_category TO aropixel_post_category
