As you probably already know, the Joomla 2.5.5 and 2.5.6 updates have been plagued with bugs. Big Bugs. Here’s another one to add to the list: jUpgrade, the Joomla component for upgrading from Joomla 1.5 to Joomla 2.5, does not work with Joomla 2.5.6, the current Joomla release. Bottom line: You need to use Joomla 2.5.4 to upgrade from Joomla 1.5.25 to Joomla 2.5.
If you are trying to migrate a Joomla 1.5 website to Joomla 2.5, most likely the migration will fail. The reason for this is that Joomla 2.5.6 is not compatible with jUpgrade. Be default, jUpgrade uses the latest Joomla version. Fortunately, you can override this.
The following prodedure explains a work around for the issue.
Note: This procedure assume you have already followed the instructions for migrating Joomla 1.5 to 2.5 and jUpgrade is failing during the migration process: http://docs.joomla.org/Migrating_from_Joomla_1.5_to_Joomla_1.6
