O365 migration From 1and1 Email

Has anyone migrated from 1and1 email (business email, webmail, and exchange configurator)? If so were there any special issues.

How many users, do you need all current data in the 1and1 copied to o365.

The simple straight forward answer the issues are the same. When one transitions from one email provider to another that deals with:
1) the change is not instantaneous
2) a decision on how to get the current data if left on server to the new server
3) how are the email clients configured and how many users are involved?
4) o365 has support/migration that might be engaged to assist with the transition
5) for safety, continuity, each user may have to have both accounts configured in the email client to cover the overlap period
6) after the initial signup, to complete the o365 setup, you would need to setup DNS records, NOTE: Do not delegate the DNS management of your domain, you have to manage it to maintain when what changes are made based on your schedule.  make sure when you are adding the MX records for the domain pointing to O365 server, make sure to pick as large a number than the one used currently for the 1and1. This will maintain your email flow while allowing you to setup and test the o365 setup, email routing within o365 if you need distribution groups, shared mailboxes, etc.

There are powershell tool for remote administration of o365 if you are so inclined.
