Getting following error when migrating from CRM 2011 Rollup update 14 to CRM 2013 sp1.
" Microsoft.Crm.CrmException: Database having version 6.0.0.809 is not supported for upgraded."

Before installing SP1 on CRM 2013 the database CRM was importing with out any issue.The only change is SP1 installation and the database I am importing is actually another copy of same organization of CRM2011.

Anyone knows what's causing the issue?
