I had the same issue and RESOLVED IT by the following
1. Move live site to test/production server

2. UPDATE the following in core_config_data:

3. Modify magento/app/etc/local.xml to point to your database

4. Delete * var/cache and var/session

5. Delete the following from the following tables which is what causes the conflict (contain non essential statistical data):
tables: report_compared_product_index & report_viewed_product_index

6. Run the following commands
chmod 755 mage
rm -rf var/cache/* downloader/pearlib/cache/* downloader/pearlib/download/*
./mage mage-setup .
./mage sync –force
./mage config-set preferred_state stable
./mage list-upgrades
./mage install Mage_All_Latest –force
rm -rf var/cache/* downloader/pearlib/cache/* downloader/pearlib/download/*
chmod 755 mage

7. run this command:
php shell/indexer.php reindexall

This step causes an error but this is normal and only happens on the product price this will be fixed further on. There error you will see is:
Product Prices index process unknown error:
exception ‘PDOException’ with message ‘SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘website_date’ in ‘field list’’ in /home/erjpub/documents/public_html/lib/Zend/Db/Statement/Pdo.php:228

8. Continue with the update by running the following commands:
./mage upgrade-all –force
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 777 {} \;
chmod 750 mage
chmod o+w var var/.htaccess app/etc
chmod -R o+w media
chmod -R 777 var/package var/locks var/report var/export downloader

9. Enter the url for your site for the update. It will take a while (long while….BE PATIENT) depending on the size of your site.

Spend 3 days trying to get this working and this is the only thing that worked for me.


Unable to reindex Product Flat Data – Stuck on Processing. ‘SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row

The catalog_product_flat_# table is a flat table containing data from EAV product catalog tables.
If you have problem with reindexing the catalog, truncate (drop the content) that table and reindex your data.

It seems that Magento doesn’t clean that table when you delete some information.

In my case, that table was full of old deleted products.
