How can I print my A4 Book now in 8"x10.5"? RESIZE?

Question

Hello
I have a book about 700 Pages already been printed a couple of times in A4 size,
Now the sponsor can only print it in max 8"x10.5"
This means the entire Book/file needs to be adjusted to this new size  in order to get it printed.
I need to know what is the best option to do this.
Can this be automadet in Indesign or trough the export via printing?
I am very thankful for any help and advice.

I appologize this Forum is confusing to me.
I posted a new question in a new thread.
I am working on a book in Indesign.I have 740 pages in total. I have black and white and color pages meaning Images.I converted the black and white images in Photoshop to Grayscale files, before I imported the imges into in design. As
to reduce printing costs my printer asked me to make sure these single
pages are safed as either color or black and white pages,so the printer will recognice those pages and will print those according to their color/ black and white profile of the images.I thought this will happen automatically since my photos, digital images are either in color or grayscale.Apperently this did not happen.My printer just told me all pages are having color profiles.So I wonder is there a way in Indesign to give single seperate pages of my bookdifferent
color or b/w profiles? so the printer who will recieve a PDF from me
does prints bacl and white in a black and white modus.

Rather than ask you for more details here, I'm going to suggest that this is so far from related to the original question that you should start a new thread. tellus exactly what you mean by "single color pages," whether you mean convert for final output and wish to leave the color intact in the document during editing or for multipurposing, the version of ID, etc.
