thanks guys ; below was my mistake.. (have question though at the bottom)

[root@rleeserver tmp]# cat yaho11.b
#! /bin/sh

dir1=$1
dir2=$2
echo $dir1
echo $dir2

find /home/"$dir1" -type d -print |
sed -e "s;/home/$dir1/;/home/$dir2/;" |
while read newdir
do
mkdir $newdir
done
[root@rleeserver tmp]# ls -l /home/xmen4/*
ls: /home/xmen4/*: No such file or directory
[root@rleeserver tmp]# ls -l /home/xmen4
total 0
[root@rleeserver tmp]# sh -x ./yaho11.b xmen3 xmen4
+ dir1=xmen3
+ dir2=xmen4
+ echo xmen3
xmen3
+ echo xmen4
xmen4
+ find /home/xmen3 -type d -print
+ sed -e 's;/home/xmen3/;/home/xmen4/;'
+ read newdir
+ mkdir /home/xmen3
mkdir: cannot create directory `/home/xmen3': File exists
+ read newdir
+ mkdir /home/xmen4/one
+ read newdir
+ mkdir /home/xmen4/three
+ read newdir
+ mkdir /home/xmen4/two
+ read newdir

I also see below working to better solution.. but what does \(/\|$\) do??

\( \) is backreferenceing 1 that I understand but what is /\|$ do??

sed -e "s;^/home/$dir1\(/\|$\);/home/$dir2\1;"

NAME
mvdir - move a directory SYNOPSIS
dir newdir DESCRIPTION
moves one directory tree into another existing directory (within the same file system), or renames a directory without moving it. dir must be an existing directory. If newdir does not exist but the directory that would contain it does, dir is moved and/or renamed to newdir. Otherwise, newdir must be an existing directory not already containing an entry with the same name as the last pathname component of dir. In this case, dir is moved and becomes a subdirectory of newdir. The last pathname component of dir is used as the name for the moved directory. refuses to move dir if the path specified by newdir would be a descendent directory of the path specified by dir. Such cases are not allowed because cyclic sub-trees would be created as in the case, for example, of which is prohibited. does not allow directory to be moved. Only users who have appropriate privileges can use EXTERNAL INFLUENCES
