ADMT Users with a ExchangeActiveSyncDevices Child Object Fail

We are currently migrating users from one child domain to another due to a
geographical location exercise.

I have run into an interesting issue with the ADMT User Migration Wizard
whereby the operation fails for any user who commonly uses an Exchange
ActiveSync device such as the Nokia smartphones we use.

The ADMT log displays the following message at the end:

ERR2:7422 Failed to move source object 'CN=username'. hr=0x8007208c The
operation cannot be performed because child objects exist. This operation can
only be performed on a leaf object.

This makes no sense because users are leaf objects, and shouldn't have any
child objects.

Looking at this in ADSIEdit, any user who has a ActiveSync device now has a
child object - CN=ExchangeActiveSyncDevices.

If the migration wizard is run on a user without this attribute then the
operation completes successfully.

Is it safe to remove this object and set the phone up from scratch, or is
there an approved method for migrating these accounts with the child object.
There doesn't appear to be a method of doing so either from the command line,
or from the ADMT itself.

Thanks in advance.

I did a migration a year ago from one forest to another, and some were AS users. I had no problems. I am curious. Create a test account currently enabled for ActiveSync and disable the feature for the user, then just migrate that account. Does it work?

I had experienced the same issue when we moved AD mailbox enabled users across domains.
Long story short, in a multiple domains forest (W2K8R2, W2K8, or even W2k3), you will encounter an issue during the user move by using ADMT or Movetree as long as the user has associated LEAF object (cn=msExchangeActiveSync\cn=iPhonedvexxxxxx).
Because we can only move leaf object between domains, not the container. the user object is a LEAF object to domain, we are supposed to move them easily by usig movetree or admt. However, it will turns to a container if it associates with msExchageActiveSynch. That is why you are able to move AD mailbox enabled users after you manually remove the cn=msExchangeActiveSync and cn=iPhonexxxxxx from the ADSIEDIT.msc.
You can also use ldp.exe to search the user object to ensure it does not have such exchange leaf attached.
