Exchange 2003 Prep for Exchange 2010

We have a Exchange 2003 Server which we can only defrag (using the system defrag) to::
Total Fragmentation - 48%
File Fragmentation - 96%
Free Space Fragmentation - 0%
The reason we checked this is that several mailboxes would not move over to the new Exchange 2010 server due to corruption.  I know that I can force the move to take place with the corruption, but what I am wondering is would it be best to use the utility ISINTEG utility to fix the corruption and not worry about the fragmentation.  I did use ESEUTIL and found that the Sapce Dump available is 22 GB.  Our Server is sliced so that the drive the database resides on is 100 GB and right now it is about 71% of that is used.  From my understanding if I run the ESEUTIL it requires 110% more space, which we currently do not have.  Any suggestions??  Thank you!

If you are doing the database defrag then only you need it. With ESEUTIL /d switch and you need 110% of actual drive. But defrag only clears the whitespace, not going to fix the corruption issue. It is better to create new db and move mailboxes to it. If you are planning to clear whitespace.

ISINTEG will help to fix the integrity. You can the ISINTEG command with -fix switch. Take backup before doing it. Below are the steps
