Pre-11.0 SQL Server versions required you to execute reconfigure after executing sp_configure. Beginning with SQL Server version 11.0, this was no longer required. The reconfigure command still exists, but it does not have any effect. It is included in this version of Adaptive Server so you can run pre-11.0 SQL scripts without modification.
Scripts using reconfigure will still run in the current version, but you should change them at your earliest convenience because reconfigure will not be supported in future versions of Adaptive Server.
