Active directory migration between 2 forests

sos2112 used Ask the Experts™
I have 2 forest which eanch one has one domain, the 2 domains have a an external trust setup between them 2 ways.

I'm trying to migrate users from domain A to domain B but keeping the source as it is so is like a copy using ADMT v3.0 but everytime i receive this error "Unable to establish a session with password export server. The specified service does not exist as an install service" when i choose the option of migrating passwords, but if uncheck that and go forward the migration fails with the errors below:
ERR2:7816 Cannot determine if source object "......" matches an object in the target forest or domain.  The handle is invalid.
ERR2:7301 Failed to migrate source object '.......'. The target object could not be created. hr=0x80070006  The handle is invalid.
So can anyone help me with this.
