Attempt to restore the attached Moodle 1.9 backup (backup-allblocks-20121120-1246.zip). Confirm that it restores with no errors, and that all blocks (which exist in both 1.9 and 2.x) are present in the restored course. Confirm that the Moodle logo image in the HTML block has been migrated (i.e. uses pluginfile.php rather than file.php). Note that any blocks which store data outside the block config will be missing any such data (i.e. the rss_client block will not contain any feeds). This is because Moodle 1.9 does not back up that information, so it's not present in order to be restored. This behaviour is therefore consistent with restoring the 1.9 backup to a different instance of Moodle 1.9.
