Number range issue while replicating customer master from 2 ECC systems to C4C

Hi Guys,

Need some help.

We have a situation where we are replicating customer master from 2 ECC systems into 1 C4C Tenant.

Now there are overlapping number ranges across the 2 ECC systems for Customer Master Records.

Will this create an issue while running standard replication transactions for initial load and delta load?

Can anyone share any thoughts.

Regards,
