number ranges in CRM -- HR integration ??

Hello All

I am working on CRM u2013 HR integration,

After replicating the organizational model and employees I found that not all of the employees have been replicated so I did changes in the number ranges that have been assigned to the employees at the table T770S0 and I tried again but still the same problem, my question is does the change in the number range causes no employee replication or just affects the business number for the newly replicated employees?

My number range assigned for the employees is external numb range
