Why it does not work for you, I can not say at the moment. My test database with wrong foreign keys can be ported without problems. My recommendation, increase the database version manually and use the migration tool to copy the database into a new one. mysql -u USERNAME -p USE DIGIKAM_CORE_DATABASE UPDATE Settings SET value=9 WHERE keyword='DBVersion'; Maik

actually, this is not really enough without adding something like <statement mode="plain">SET FOREIGN_KEY_CHECKS=0;</statement> before trying to migrate the quirky tables. My problem was with the Tags table because of this in the (new) dbconfig.xml: <statement mode="plain">RENAME TABLE Tags TO Tags_old;</statement> <statement mode="plain">CREATE TABLE Tags LIKE Tags_old;</statement> <statement mode="plain">ALTER TABLE Tags ADD CONSTRAINT Tags_Images FOREIGN KEY (icon) REFERENCES Images (id) ON DELETE SET NULL ON UPDATE CASCADE, ADD UNIQUE(pid, name(100)), ENGINE InnoDB;</statement> <statement mode="plain">REPLACE INTO Tags SELECT * FROM Tags_old;</statement> <statement mode="plain">SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO';</statement> <statement mode="plain">REPLACE INTO Tags (id, pid, name, icon, iconkde, lft, rgt) VALUES (0, -1, '_Digikam_root_tag_', NULL, NULL, (SELECT MIN(tl.lft) FROM Tags AS tl), (SELECT MAX(tr.rgt) FROM Tags AS tr));</statement> <statement mode="plain">SET SQL_MODE=@OLD_SQL_MODE;</statement> <statement mode="plain">UPDATE Tags SET icon = NULL WHERE icon = 0;</statement> Only the last statement fixes the invalid references to an image with ID 0 but the foreign key constraint was added before that already and this is why the REPLACE INTO failed.
