If a new nocase sortorder for Chinese or Japanese character sets is configured as Adaptive server's default sortorder. Before downgrading to a 15.0 or 15.0.1 release, switch to a sortorder that is compatible to that release. Switching a sortorder means all user indexes need to be reindexed. Please refer to System Administration Guide Chapter 9 "Configuring Character Sets, Sort Orders, and Languages" for details on how to change server's default sortorder. If sp_downgrade is called when the new nocase sortorder is in use, the error message "Cannot downgrade to '%1!' server, which does not support server's current default sortorder" will be raised and the downgrade process will be aborted.
