Migration will be from 2007 to 2010/2013 then from 2010/2013 to 2016

Why do we need to migrate from 2007 to 2010/2013 then from 2010/2013 to 2016?

As per Microsoft limitations, we cannot migrate to any version of Exchange without passing the next version


Process plan & schedule day's to Migrate Exchange Server 2007 to Exchange 2016:

  • Install Exchange 2010/2013 into Exchange 2007 organization.1-2 day’s
  • Configure Exchange 2010/2013 and Exchange 2007 coexistence. 2-3 day’s
  • Migrate Exchange 2007 mailboxes, public folders, and other components to Exchange 2010/2013.2-3 day’s - Depending on Complexity
  • Configure Exchange 2010/2013 SSL-Cert. 1 day
  • Decommission and remove all Exchange 2007 servers.1-2 day’s
  • Install Exchange 2016 into Exchange 2010/2013 organization. 2-3 day’s
  • Configure Exchange 2016 and Exchange 2010/2013 coexistence. 2-3 day’s
  • Migrate Exchange 2010/2013 mailboxes, public folders, and other components to Exchange 2016. 2-3 day’s (Depending on Complexity)
  • Configure Exchange 2016 SSL-Cert. 1 day
  • Decommission and remove all Exchange 2013 servers.1-2 day’s

    so a total is 15-20 days’ work (rough estimate) 




Decommissioning Exchange Server 2007 Process  :

The steps to decommission Exchange Server 2007 are listed below:


1. Backup Exchange Server along with its User Mailbox database(s) and Public Folder database(s)


2. Migrate user mailboxes with their complete properties and settings to another Exchange Server


3. Migrate Public Folders to another Exchange Server


4. Disable Local Continuous Replication of User Mailbox Database and Public Folder Database


5. Remove User Mailboxes


6. Stop the usage of Exchange Server 2007


7. Remove the Public Folder Database

 

7a. Force removal of Public Folder Database


8. Remove the User Mailbox Database


9. Remove the Storage Groups


10. Remove or move the Offline Address Book (OAB)


11. Move Routing Group Connector to another Exchange Server


12. Remove Exchange Administrative Group, if no other Exchange Server is installed in the domain.


13. Uninstall Exchange Server 2007








 Hardware & Software Requirements:


- 2 Servers for Migration steps.


- 2 Server’s if we need to establish 2 parallel Exchange server’s one as a backup server.


- 2 SAN/NAS Storage Virtual Disks if we going to use DAG as High Available Database with the same drive letter.


- Windows Server 2012 R2 /2016 License.


- Windows Server UsrCALs


- Exchange Server 2016 License.


- Exchange Server UsrCALs


-- Mailbox Exchange Repair & Recovery Software, in case we got corrupted data.


- Offline Copy of the mailbox database:


-
Exchange database (.edb)


- Transaction log (.log file).


-
Checkpoint file (.chk).


-
Reserve log files (.jrs).


-
Temporary file (tmp.edb).


How to Calculate Space for new Exchange Server :


Space depends on Number of Org Users, Here we have 200 users, with 4GB Quota


 (200 * 4GB ) +(200*15MB)= (800GB +3000MB )   (no of mailbox’s * Quota ) + ( no of mailbox’s * whitespace)  Active

 (200 * 4GB ) +(200*15MB)= (800GB +3000MB )   For use ( Database Availability Groups  )  DAG’s for High Available    Passive


Note:
Whitespace isn't freed up until after the retention period is passed for the mailboxes you have moved, also not all the space of a mailbox will be freed up so trying to stop stores expanding by moving mailboxes out of them doesn't really work, you would be better off moving the mailboxes to a fresh store and removing the old store, this will give you the added advantage of defragging the store as well and should result in smaller databases

It depends on local regulatory, financial data could be kept for at least N years before it can be purged. financial auditors will audit on the what, where, when, which, how of your data is being stored, modified, deleted.

the Confidentiality, Integrity, Availability (so called CIA) should always be taken into consideration for the information system that involving data.

fraud could also happen if the data integrity was compromised regardless it's whether delete query or flag tagging.

and it not only applied to MS Access but in general applied to other DBMS/ RDBMS as well.

Hi Charlotte.

Andrew, my biggest pet peeve about Access training and "how-to" articles is that they address the tools in Access but rarely the underlying design principles that are essential in building a database.

Indeed. You make an excellent point, one that I hope Dale (author of this article) and other readers will take note of for future article submissions. Perhaps an article explaining just that? :) Yes, there are already many explanations to be found with Google.

The difficulty I see here is that the term "Database" is so broad that to a layman, can also sound such technical a term as to discourage the excitement of learning about it. A title like "Learn the underlying design principles involved in building a database" wouldn't likely attract my attention, nor dare I say it, most others who don't have a vested interest in learning Access or other related software.

Yet if I saw something I could relate to, like "Learn to organize your favorites so that all browsers can use them" and do that in Access, well, that might be something I'd click on and actually read. The trick is in finding a way to educate using a hook and subject matter that will entice people to want to read and want to learn more. That's why I think different ways of educating on the same topic is so important.

Take the question: What is a database?

If I "Google" that as kindly suggested to me earlier by Joe, then the first thing I get is that its "a structured set of data held in a computer, especially one that is accessible in various ways."

Sounds too much like programming to me and doesn't really entice me to continue digging in order to learn more. I think that's a core problem of why many don't turn to something like Access and use Excel instead - it's too much like programming.

It's only when the penny drops (and for me, it's by reading articles like this one out of need while editing) that you start to get more interested in digging further. Editing articles such as this one prompt me to ask the question, how can I relate what I do in Excel, to do it even better in something like Access?

I confess I have a vested interest in promoting for these types of articles, both as someone who wants to read them, and someone who gets to edit article submission here in a volunteer Page Editing capacity. We already have a ton of technical "how to" articles as you say, but I think that's a good thing and keep them coming I say!

Yet I think interestingly written articles that will attract the "Joe Averages" of the world, who use Excel to store information in mostly because it seems easier to come to terms with using, yet will never know until enticed to dig deeper just how much easier life could be by delving into the cryptic world of databases.

That's the type of "How to" article I'm trying to promote be written here. Is there a single way of doing that? I don't think so. I'm just trying to encourage readers who have the necessary knowledge to give it a go. Hope that makes sense? :)

Look for a book by Michael J Hernandez, "Database Design For Mere Mortals"

Thanks for the heads up. I'll most certainly do that.

Regards, Andrew

for those of you using the Linked Table Manager, the latest version (posted in the original article) is 1.14.07, which fixes several bugs, including one which caused the linking operation to fail if the path to the backend is > about 100 characters (has to do with the Title property of the FileDialog).

enjoy.
