Sql-server – DBCC CHECKDB errors migrating from SQL Server 2000 to SQL Server 2008R2

I'm getting integrity issues after I migrate a DB from SQL Server 2000 to SQL Server 2008 R2.

I ran a DBCC CHECKDB on the old db, and it returned no issues. Then I FTP-ed the backup file to the new server and restored it to a new database. I immediately ran a DBCC CHECKDB on the new DB and got the errors below. Is there something I'm doing wrong in the migration?

Could the FTP process be corrupting the file? (sizes were the same) Or, is there a way to fix these errors? (I tried various CHECKDB repair options and they didn't work).
