I am considering switching everyone in our office over to Office 365. We currently host our mail with GoDaddy. GoDaddy indicated to due so we have to:
-Download all our mail from our 14 email accounts
-Cancel the email address's from GoDaddy's servers
-Recreate the accounts on MS Server's
-Upload the data back to the accounts

Doing this for 14 email account is obviously quite cumbersome and I can definitely see something going wrong. Does anybody know of any easier routes to accomplish the migration?

I contacted MS and they referred me to a "Partner", however I haven't heard from them in a couple of days.
