HCM 8.9 / 8.47 MSSQL 2005 upgrading to HCM 9.1 / 8.52 / MSSQL 2008. SQL Server Native Client Compati

HCM 8.9 / 8.47 MSSQL 2005 upgrading to HCM 9.1 / 8.52 / MSSQL 2008.    Issue, 8.49 Demo is on MSSQL 2005, new 8.52 demo is on MSSQL2008.    On my Client machine where Change assistant (8.52) is installed, I can connect to both databases using apps. designer, data mover, etc.   However when I try to use Change Assistant and configure the environment, the "test Connection" fails when I try to access the MSSQL 2005 environment.    Tracing gives the following message. 

 1-6      09.15.02    0.003000 Cur#0.1952.HCM89DMO RC=0 Dur=0.000000 XER rtncd=0 msg=Invalid SQL Server version (minimum is SQL Server 2008) (SQLSTATE PS078)

My question is, can you connect to both a MSSQL 2005 and 2008 using SQL Server Native Client 10.0?    I have installed a DSN for both the 32 bit version and 64 bit version, but it still doesn't work.
