Use iMac late 2009 as a second display connected to iMac late 2014
Not sure if possible, is it possible to use my iMac Late 2009 as a second display for the iMac late 2014 build.
The old iMac has a Mini display port and the new iMac has only thunderbolt connections?
I am confused after reading apples FAQ's
Appreciate any help, thank you

Yes, the iMac late 2009 supports Target Display Mode (TDM)
Cable Supported: Mini DisplayPort to Mini DisplayPort
Port on Source Computer: Mini DisplayPort or Thunderbolt
Thunderbolt ports are backwards compatible, meaning they support MiniDisplay Port cables. Your iMac 2009 with MiniDisplay Port does not support Thunderbolt. So you will need a Mini DisplayPort to Mini DisplayPort cable; this would then be plugged into Mini DisplayPort in 2009 iMac and Thunderbolt port on 2014 iMac.
Command F2 on the 2009 iMac would put this computer into TDM, with the 2014 iMac as the source computer.

I know this reply is a bit late to the party, but for the benefit of future readers, the iMac Late 2009 does support Thunderbolt (not just Mini DisplayPort). Take a look in "About this Mac" under System Information and you will see Thunderbolt listed under the Hardware section.
