Show specific data from a partitioned table in SQL Server. Data Archiving using Table Partitions
If you want to archive it and do not want it to be returned in default queries, then remove it from the table and add the filegroup for this partition to another table tblUserDetailsArchive. Then any user could query

select * From tblUserDetailsArchive  


or

select * From tblUserDetailsArchive where datecreated &lt; '20140101'      


to get the older rows if required.
