Before you begin, you’ll need the answers to following
questions and to complete these tasks. Feel free to print
out this page and use it as your migration checklist:
What email service are you currently using?
Who is your DNS provide? Who is the admin to the
account, and what are the credentials?
How many inboxes are there?
What items do you want to migrate? Just the
emails? Contacts? Calendar items?
Do you have any shared inboxes?
How many domains do you have?
How many email aliases are there?
How large (in GBs) are each of the mailboxes?
Create a BitTitan account
You have the first Name, last Name, username and
password for all your users in an excel spreadsheet
(unless you are planning to be using Enable SSI,
Source-Side Impersonation, on GoDaddy)
Calculate your migration time. Microsoft's policy
limits the transfer rate of data to 10GB per user/per
day. What does that mean? Take a list of all the
mailboxes you have today and rank them by size,
from largest to smallest. If the largest mailbox of all
of them is 18GB, then it will take 2 days to migrate.
If the largest of the bunch is 7GB, then it will take
under a day to migrate all of them.
