Microsoft does not provide any drivers to connect to Sybase. Sybase have their own drivers (only 32 bit) but they do not have 64bit. I cant understand why they dont provide the 64bit drivers. Flipside of that why dont Microsoft provide any drivers for SSIS.
If you are using Oracle or Teradata as your source you can have Attunity Connectors for FREE as long as you have got SQL Server Enterprise Licence.
Unfortunately Microsoft didn't sponse Sybase Connector from Attunity. There is another option available from Data Direct. You have to purchase both connectors from respectable vendors. These connectors are not cheap!!
