Hi tripfour,
Upgrading from MXI to MXI-2 should not be too complicated. The first obvious change is the hardware itself. When you upgrade from an AT-MXI system to a PCI-MXI-2 system, the MXI boards are the only hardware you need to change.
Additionally, you will need to upgrade your NI-VXI driver software to a version that supports the MXI-2 hardware. Existing instrument drivers and VXI or VISA based programs created for VXI/VME instruments and MXI should be compatable with MXI-2. You can download the latest VXI drivers at http://www.ni.com/support/vxi/drivers.htm.
If a driver does not exist for your operating system, it may be possible to use the PCI-MXI-2 Driver Development Kit to create a driver. For more information on the MXI-2 DDK, please review Know
