EDIT: The code has been modified so only the child directory is modified.
Here is a sh script that will surely work:
Code:
#!/bin/sh

cat /dev/null > tmp
for f in $(find -type d); do
  echo "$f" >> tmp
done

cat /dev/null > tmp2
while read line; do
  depth=$(echo "$line" | grep -o "/" | wc -l)
  echo "$depth|$line" >> tmp2
done < tmp

sort -nr tmp2 > tmp
while read line; do
  folder=$(echo "$line" | cut -d'|' -f2)
    parent=${folder%/*}
    child=$(echo ${folder##*/} | tr [A-Z] [a-z])
  newfolder=$(echo "$parent/$child")
  echo mv "$folder" "$newfolder"
done < tmp

exit 0

It's a bit hackish but the trick is to rename deeper directories first
- The first block of code creates a tmp file containing what find finds
- The second block calculates the depth of the directories and writes to tmp2, for each directory, a line in the form "5|/path/to/the/direc/tory". Then the file is sorted so deeper directory are first in the file tmp
- The third block actually rename each child directory with a pattern of choice
Remove the echo on the last line in the third loop to rename the files

I hope you'll find this script useful!

rmvb

rmvb(9F)						   Kernel Functions for Drivers 						  rmvb(9F)

NAME

       rmvb - remove a message block from a message

SYNOPSIS

       #include <sys/stream.h>

       mblk_t *rmvb(mblk_t *mp, mblk_t *bp);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       mp    Message from which a block is to be removed. mblk_t is an instance of the msgb(9S) structure.

       bp    Message block to be removed.

DESCRIPTION

       The  rmvb()  function  removes a message block (bp) from a message (mp), and returns a pointer to the altered message. The message block is
       not freed, merely removed from the message. It is the module or driver's responsibility to free the message block.

RETURN VALUES

       If successful, a pointer to the message (minus the removed block) is returned. The pointer is NULL if bp was the only block of the  message
       before  rmvb() was called. If the designated message block (bp) does not exist, -1 is returned.

CONTEXT

       The rmvb() function can be called from user, interrupt, or kernel context.

EXAMPLES

       This  routine  removes  all  zero-length M_DATA message blocks from the given message. For each message block in the message, save the next
       message block (line 10). If the current message block is of type M_DATA and has no data in its buffer (line 11), then remove  it  from  the
       message (line 12) and free it (line 13). In either case, continue with the next message block in the message (line 16).

	 1  void
	  2  xxclean(mp)
	  3	 mblk_t *mp;
	  4  {
	  5	     mblk_t *tmp;
	  6	     mblk_t *nmp;
	  7
	  8	     tmp = mp;
	  9	     while (tmp) {
	 10		      nmp = tmp->b_cont;
	 11		      if ((tmp->b_datap->db_type == M_DATA) &&
				    (tmp->b_rptr == tmp->b_wptr)) {
	 12			   (void) rmvb(mp, tmp);
	 13			   freeb(tmp);
	 14		      }
	 15		      tmp = nmp;
	 16	     }
	 17  }
