When a NetCommunity database is attached to an instance of SQL Server Enterprise, the database will take advantage of some data compression available only in SQL Server Enterprise or Developer editions. If you attempt to restore a NetCommunity database backup to any version of SQL Server other than SQL Enterprise or Developer 2008 or later when the backup was taken from SQL Enterprise, the restore will not be possible as the compression is not supported on other versions of SQL Server.
