Apil,
We provide support for any volume for three years from the release of that volume so support for 2007 Volume 1 ended over five years ago. For the controls, yes you will need to replace the controls manually. For an approach to move from the UltraWebGrid to the newer controls refer to the following:

Note that you may also want to consider using our newer igGrid built on top of the jQuery framework if it is an option for your grid.
