We will be updating MySQL from version 5.0 to version 5.1 on your database server LPSQL04 on 10th May 2012 12AM Pacific time. We have backups on hand for all databases in the event of any issues with the upgrade process.
Please note MySQL prior to 5.1 has limited usernames to 16 characters. In those versions of MySQL, when a login username longer than 16 characters is sent to the server it is silently truncated to the 16 characters limit. In MySQL 5.1, all characters submitted for the username are checked during authentication. This change means that any user submitting more than 16 characters as their login username will fail to authenticate once the server is upgraded. To ensure the upgrade goes smoothly for you, if your sites use database logins longer than 16 characters, please correct database connection details to only send the first 16 characters of the current login usernames by truncating them.
