Renaming files recursively and moving them inside one single directory

Question

I have a project with 500k users in CentOS. The picture file/directory structure was setup like this (yeah... i know):

user/0070/ this is the user ID / 1000, so that all users in the range of [70000-70999] are inside this directory
user/0070/70909/ this is the user ID
user/0070/70909/p.jpg profile picture (100x100)
user/0070/70909/x.jpg full size picture

I'm moving everything to a CDN, so I need to convert that structure into this:

user/70909.p.jpg profile picture (100x100)
user/70909.x.jpg full size picture

Of course, the only way to achieve that in a period of time is to execute a script that renames and moves all files inside one single directory. Any ideas? Thanks!

@JamesRyan do you suggest leaving them as they currently are? — Carlos Santos, Dec 31 '14 at 07:21
They have probably been setup this way to make them manageable yes. Surely it is trivial in any script to use the extra folder? — JamesRyan, Dec 31 '14 at 16:05

In bash:

cd user
for i in *; do
    for j in $i/*; do
        for k in $j/*; do
            mv $k `basename $j`.`basename $k`
        done
    done
done
