D365 tenant to tenant migration?

(0) ShareShare

Posted on by

Hola,

im doing D365 CE t2t migration one of my clients, but now i faced tricky problem when creating user mapping file for sandbox. Problem: currently same time we are doing O365 t2t activities and source tenant upn domain @xxx.com has not been moved yet to destionation tenant, so can i use eg. @xxxx.onmicrosoft.com what is destination tenant default upn or should i wait that @xxx.com address is successfully moved to tenant and then use that to create mapping file? 

thanks

    Hey Purtsi.

    If you're doing a tenant to Tenant, that mapping file is important.  However, it doesn't have to be with your custom domain (@xxx.com)  You can use the @xxx.onmicrosoft.com as long as the value exists.

    Best regards
