V3 upgrade of custom DB fields

Does anyone know if the upgrade for cs-cart will deal with any additional columns that have been added to the DB? I.e. if I were to install cs-cart V3.0.2 and then manually add the columns to the DB, will the upgrade process move the data from the 2.2.4 DB to the 3.0.2 DB?



I'm going to assume not, but thought I'd ask.
