Cannot import data from one Kentico to another - wrong hotfix - but in database settings versions ar

Hi,I have a problem when exporting and importing site from one Kentico into another. Problem is that I got thisError during temporary files creation. Original exception: [ImportProvider.LoadObjects]: Cannot import data from newer hotfix version '50' to current hotfix version '0'.But when I checked in both databases I see the same values for keys below:MSDBVersion: 9.0CMSDataVersion: 9.0CMSHotfixVersion: 50Also, when I tried run hotfix installer on site with older hotfix it also says installed hotfix version is 50.
