Acronis True Image
One tool that we often use is Acronis True Image with Universal Restore. Acronis True Image allows us to easily migrate off of older hardware onto new hardware with it support of dissimilar hardware types. You can take and Image of an application running on an older outdated piece of hardware and restore that image onto newer hardware. It does not matter if the seed or target servers have a Raid configuration, you simply re-apply the appropriate drivers and it works.We have done this many times and it is worth checking out.
This functionality is very similar to Ghost and although I have never used Ghost, here is a comparison of Ghost vs True Image.
