AD and Enterprise User Mapping

Hello All,

We are moving from one AD domain to another  AD domain and there is a change in the account name.

We created Enterprise Aliases for all AD accounts with Current AD group and now planning to go with new AD domain that group have different name account.

Ex:

Old Ad group account in BO is kumaK  and it having alias with same name and in AD group account name is KumarK.

Please let us know  if there is any solution to map account with different names.

Thanks in advance to all.
