This time I tried from 1.5.1.3 to 1.5.6.3 but I receive the below error during the upgrade - I assume the error seems to be that the upgrade tries to create all the tables rather than checking for existence and then to insert if there are changes ...
please allow the question if the software is actually tested prior to release.Notice: Error: Table 'address' already exists
Error No: 1050
CREATE TABLE `address` ( `address_id` int(11) NOT NULL AUTO_INCREMENT, `customer_id` int(11) NOT NULL, `firstname` varchar(32) NOT NULL, `lastname` varchar(32) NOT NULL, `company` varchar(32) NOT NULL, `company_id` varchar(32) NOT NULL, `tax_id` varchar(32) NOT NULL, `address_1` varchar(128) NOT NULL, `address_2` varchar(128) NOT NULL, `city` varchar(128) NOT NULL, `postcode` varchar(10) NOT NULL, `country_id` int(11) NOT NULL DEFAULT '0', `zone_id` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`address_id`), KEY `customer_id` (`customer_id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci in /home/_folder_/_domain_/system/database/mysql.php on line 50
