Desktop Migration tool provides incomplete record set

I am migrating my QB Online company to Desktop (30 day trial)  to see if it better suits my needs. I have tried multiple migrations and regardless of many attempts I am always missing some recaords. These missing records do not fall under the "what doesn't get migrated" category - they are the same as records that do get migrated and they are just missing. I notice during the Desktop Migration process it always stops at 10,000 records. Is there a finite limit to the number of records it can migrate?
