Migrating
Exchange to Office
365BY JAMES DALTON
I have created this presentation over the last 15 hours to demonstrate my ability to take on the
task of migrating exchange to office 365. Although I have not taken on a migration of this scale,
I do have the ability to take on this task.
Not only am I a qualified option, I have several strong skills that will demonstrate I am one of your
strongest candidates.
Owning my own business (Dalton Technical Solutions, LLC) there have been several items clients
who have asked for tasks that required research my own solution. These skills were developed
as I obtained a Bachelors in Economics and Psychology at The University of Kansas. So much
information is available online, and I have the ability to get the right information using analytics.
I rose through the ranks of several entry level positions by streamlining tasks through
technological solutions; saving companies tens of thousands of dollars by creating new
procedures.
I obtained a position on a helpdesk and decided to join Centriq’s 4 month extensive, hands on
program starting a foundation as a network administrator, where I became very familiar with
Server 2012, Active Directory Domain Services & Powershell 4.0. Managing groups and group
policy, routing and remote access, and configuring backups became familiar with VMWare
Hyper-V labs brought all these processes out of the textbook and into practice. I know I can
compete your migration project. I’ve already acquired a tutor at Centriq who has the ability to
train me on any aspect I am unfamiliar with. Good luck with your interviewing; and consider me
as an option.
Why move from Exchange Server
to Microsoft Office 365
Exchange Server has been a way to maintain user mail onsite for
years, so why would a company have the desire to move the mail
server to a cloud?
First, let’s look at a traditional (rudimentary) diagram of the
Exchange Server used by most companies.
Information obtained from: https://www.youtube.com/watch?v=ZtZyQkTmOIw
o Exchange has the benefit of being located on-site
o Many File Server’s are needed to support the end users
o Since mail is located on the local server, archiving and backups
generally also take place in house
o All Remote Users need to be verified through the server , as do
any password changes, profile adjustments and additions using
more bandwidth
o Any disaster to the server (flooding, power shortage, hacking or
acts of nature have the potential to bring down all mail, including
archived messages
o The following slide shows a post migration server (in a rudimentary
format)

The Benefits to a cloud based server like Office 365 can be seen
clearly:
o Decreased infrastructure decreases maintenance, and increases
operational effectiveness
o Less File Servers are needed since data traditionally saved to the
Server are hosted by SharePoint
o Information stored on local drives and units are now supported by
OneDrive
o Remote Users are now authenticated by Azure (the infrastructure
used to support Office 365
o There is no longer a need for Exchange Mail servers, nor VPNs
There are several types of Migrations based on several factors:
How many sites, domains, child domains, e-mail accounts are
located throughout the company?
What is the timeline for the migration, what version of exchange is
utilized by the company and are there are their other types of e-
mail supported?
Is third party software used to assist with the migration, such as
Migration Pro, or Office 365 Migrate, or does the company want to
use PST files imported and exported for a free version?
Despite the obvious advantage to cloud computing, Several Factors need
to be considered before jumping right in.
o How is Active Directory setup as far as synchronization is concerned?
o Are the Public Folders going to transfer smoothly to 365s answer of using
SharePoint?
o How is the e-mail security going to be effected? Especially antispam
ware.
o How will the issue of calendar sharing and address books be addressed
o And one of the biggest issues is the archiving issues. The end user wll
flood the helpdesk asking why they went from 3 years of saved e-mails
to 2 days. This issue can be overcome by remapping.
Types of Migrations
Depending on the corporate needs, network traffic, internet
speed, and the version of Exchange, the timeline of the
migration, there are 4 different types of Migration.
Remote Move:
This is the hybrid answer and while utilizing the cloud, there is
still an active mail server onsite. This is the best option if using
Exchange Server 2010, or over 2000 mailboxes .

Types of Migrations
Staged:
In a Staged Migration, mailboxes are moved over in batches.
This is done by replicating users through Active Directory either by a CVS file or traditional Excel File.
This is done over a period of time, and when using Exchange 2003 or 2007.

Types of Migrations
Cutover:
This is a short term fix, and used when there are less than 2000
mailboxes. The user identities will be managed by 365.
Types of Migrations
IMAP:
This type of migration is used for large number of user
mailboxes, and is already on online platform to allow end
users the ability to check e-mail via mobile devices. This
leads to a discussion of some of the challenges created by
Migration.
Information Obtained from TechNet: https://technet.microsoft.com/en-us/library/jj200751(v=exchg.150).aspx
There are several issues that can come up during the process of migration, especially if steps are
overlooked. These include:
Calendar Sharing among users
Problems with Address Books
Tasks not transferring from one system to another
Issues with archived messages and archiving messages.
Carefully considering the different options when migrating, following steps from both Office 365,
other third party directions and Microsoft Help such as TechNet.
A competent administrator/engineer who has the ability to troubleshoot problems by testing
options through Virtual Machine Software such as VMware; an individual who posses
exceptional research abilities, and has the ability to reach out to third parties familiar with the
process is the best way to overcome these challenges and have a smooth migration where end
users are not effected by the changes made.
