Migration Tenant to Tenant in IMAP

hello everyone,

I have to do a tenant to tenant migration and for various reasons I only have imap available, and a single administrative user on the active tenant I have contoso.com which is also part of other domains, I have to bring contoso.com to a new tenant, before the migration I called the new tenant contoso.net. I use the microsoft migration tool but it tells me that it does not find the username email address  in the new tenant where I created email address but is different the @domain. in the meantime however the users must continue to use the old tenant until the cutoff. What should I do?

    Please follow below as IMAP requirement:

     

    - Create Migration Endpoints: Set up migration endpoints in the Exchange Admin Center (EAC) for both the source and target tenants. Use outlook.office365.com as the IMAP server for both
    - Configure Migration Batches: Create migration batches in the EAC. Ensure that the email addresses in the migration CSV file match those in the new tenant contoso.net
