Upgrade from 1.x to 2.x version : localizer table

The following SQL code (form MySQL) extracts the translations inserted for taxonomy and menu with the version 1.x and put them in the
new strings translation engine (localizertranslation table) :

insert into localizertranslation
(object_key, object_name, object_field, translation, locale)
SELECT m.mid, IF(m.type=115, 'menu', 'menu_item'), 'title', substring( t.translation, 1, 255 ) , t.locale
FROM locales_source s
INNER JOIN locales_target t ON s.lid = t.lid
INNER JOIN menu m ON substring( s.source, 1, 255 ) = m.title
WHERE m.type IN (115,118) AND substring( t.translation, 1, 255 )<>'';

insert into localizertranslation
(object_key, object_name, object_field, translation, locale)
SELECT td.tid, 'taxonomy_term', 'name', substring( t.translation, 1, 255 ) , t.locale
FROM locales_source s
INNER JOIN locales_target t ON s.lid = t.lid
INNER JOIN term_data td ON substring( s.source, 1, 255 ) = td.name
WHERE substring( t.translation, 1, 255 )<>'';

insert into localizertranslation
(object_key, object_name, object_field, translation, locale)
SELECT v.vid, 'taxonomy_vocabulary', 'name', substring( t.translation, 1, 255 ) , t.locale
FROM locales_source s
INNER JOIN locales_target t ON s.lid = t.lid
INNER JOIN vocabulary v ON substring( s.source, 1, 255 ) = v.name
WHERE substring( t.translation, 1, 255 )<>'';
