Hi again,

Thank you for the response. Just to make sure I understand it right, I will
repeat the steps for the "Microsoft Shuffle" and put some questions of mine
in brackets ;-)

1. Export User Attributes 

(using LDIFDE or CSVDE?)<<<<whichever is your preference.  I'd use CSVDE
since you're not likely to re-import this later for modifications to an
existing account.  It's just for reading.

2. EXMERGE export mailbox data into .pst file 3. Stop ADC connection 4.
disassociate the 5.5 and 2000 objects for this user [msexchadcglobalnames
attribute needs to be cleaned]

(please explain a little bit more, do I only have to clean that attribute in
AD? What should I do on the 5.5 mailbox for this step?)<<<<<<<nope.  You
have to clean both 5.5 and 2000 objects.  There's a kb that describes this: 

5. Wait for replication
6. Remove Exchange Attribute from the AD user object 7. Create mailbox in
site needed 

(should i do this either by creating a new user or creating a new mailbox
for the old user?)<<<<<<<A new mailbox for the old user.  That's really what
you're after from what I understand of your post.

8. Import User Data 

(LDIFDE / CSVDE; maybe not needed [step 7]?)<<<<<<< I'd be inclined to do
this with a script, but I'm comfortable with that.  For a one-off move, I'd
just manually do this part.  Importing the user data is needed to make it
the way it was in terms of dg membership and addresses, phone numbers, etc.
The hard part is gaining information about public folder permissions.  I
would tend to treat him as a new user and have him go through the process of
public folder permissioning already in place.

9. EXMERGE import data into new mailbox
10. Restart ADC and check for correct replication

Well, sounds good in my opinion, just the small questions I have in mind.
Hope you find the time to answer them for me ;-)
