Upgrading to version 1.6 from 1.5 via SSH

This is a short explanation on how to upgrade to version 1.6 from version 1.5. I will continue to add to this WIKI as I have time.

rm -rf var/cache/* var/session/*
./mage mage-setup .
./mage config-set preferred_state stable
./mage list-installed
./mage list-upgrades
./mage install Mage_All_Latest --force
php shell/indexer.php reindexall

Potential problems with your upgrade

If your install encounters unique constraint issues you may want to consider modifying your /app/etc/config.xml with the follow:

Original Value

<initStatements>SET NAMES utf8</initStatements>

Modified value

<initStatements>SET NAMES utf8; SET FOREIGN_KEY_CHECKS=0; SET UNIQUE_CHECKS=0;</initStatements>

I haven’t come across the unique constraint error but completely disabling the database’s mechanism to keep itself consistent seems a too heavy-handed approach. (fooman)

But if you are having constraint errors the above helps (brent w peterson)
