I have managed to upgrade one site from 1.7 to 2.5. I used SPUpgrade which I believe was not correct. I then used SPTransfer. Result is everything doubled - 2 x menu, 2 x articles, etc. Gantry would not uninstall. Cant find the component to delete manually. I then reinstalled gantry and I am getting this:
The database row is empty.JTableAsset: :store failed
Duplicate entry 'com_gantry' for key 2 SQL=INSERT INTO `med_assets` (`name`,`title`,`rules`,`parent_id`,`level`,`lft`,`rgt`) VALUES ('com_gantry','gantry','{}','1','1','109','110')Component Install: DB function reports no errors
