Backup database in SQL Server 2012 and restore this backup in SQL Server 2014

First what I do is to check consistency of database in SQL Server 2012: CHECKDB (DATABASE1) And it is ok, no errors and warnings. Next I do FULL backup and restore it on another machine with has SQL Server 2014 using SQL Server Management Studio with WITH REPLACE option. However after I run CHECKDB (DATABASE1) I receive consistency errors messages: Msg 8939, Level 16, State 98, Line 1 Table error: Object ID 293576084, index ID 67, partition ID 72057594074628096, alloc unit ID 72057594126598144 (type In-row data), page (1:5589561).

CHECKDB found 0 allocation errors and 8 consistency errors in table 'TABLE1' (object ID 293576084). CHECKDB found 0 allocation errors and 8 consistency errors in database 'DATABASE1'. repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (DATABASE1). Am I doing something wrong with backup restoration?
