Hello all,

I am in the process of migrating from desk.com to service cloud and had a question.  During the migration the desk migration wizard stopped working.  My team and I think it is becase of custom domain we started to roll out but have not yet applied to all users.  I was wondering two things,
1. How is the desk migration wizard related to my salesforce org?

2. Will changing the username of the account associated with the org break everything?

Thanks for any help.
