Migration from On-Premise Exchange 2007 to O365

Hello All,
I am looking for a PDF or a case study on Migration from Exchange 2007 Geo Clustered Environment to O365 and if possible Challenges Faced during the process.
Regards
Sathya

I think you need to check with MS Partners - I am not aware of any specific single document which covers everything and all the challenges , of course there are many from Public Folder Limits to Name Space to GAL you name it- depending how large is the environment
you are moving from.. ..

Error migrating user from on-premises Exchange to Exchange online

We have a hybrid configuration with our on-premises Exchange 2010 server and our Office 365 Exchange Online server (if this should be posted in the Exchange 2010 forum instead, let me know, but I figured we have one of each). We have been doing remote
moves, and all but two of them are finished. The two remaining are refusing to go, and I've done extensive searching but haven't been able to resolve the issues.
The first mailbox returns this error message:
Error: MissingExchangeGuidException: The user object for ‎nnn
does not have a valid ExchangeGuid property and cannot be migrated.
The second mailbox returns this error message:
Error: MigrationTransientException: Couldn‎'t find a move request that corresponds to the specified identity
<‎identity>.
We've tried moving both mailboxes several times (deleting the migration batch after each error) with no luck. The migration for both of these users are being done as separate batches with one user in each batch. They are being created via the
Exchange Admin Center from the Office 365 admin portal. Any suggestions on what to do next?

Hi Dave,
I have gone thorough your query, its ok. Pplease follow this informative article that provides the steps Mailbox Migration to Exchange Online : https://technet.microsoft.com/en-us/library/jj863291%28v=exchg.150%29.aspx
In addition if you want to move mailboxes automatically you may also have a look on
Lepide Exchange Recovery Manager that could be a good alternative solution for you.
It is complete disaster recovery, backup restoration, and Exchange to Exchange or Exchange to Office 365 migration tool and one stop solution.

Migrate SBS 2008 with exchange 2007 to office365

Hi, we have a sbs 2008 with exchange 2007 the boss got the idea to move the E-mail to office 365, i have done some research but still have some questions, now i am not an expert on exchange, could some one tell me if this is a straight operation going from
exchange 2007 to office 365, is it supported or do we have to move to exchange 2010 and then to office 365?
Thank you very much in advanced.

Yes, going from Exchange 2007 to Office 365 is supported. You want to run a Migration.
Check out this link for exact instructions on what to do for the migration:
http://help.outlook.com/en-US/140/ms.exch.ecp.emailmigrationwizardexchangelearnmore.aspx
Then, when you are ready to setup Outlook with Office 365, check out this link to make Outlook use the public Autodiscover rather than SBS Autodiscover:
http://www.mcbsys.com/techblog/2011/08/using-office-365-in-an-sbs-2008-environment-take-2/
I just did a cutover migration from SBS 2008 to Office 365 using both these websites and it went off very nicely.
Good luck on your migration.
Oh, and if you only use Office 365 for email, it is $4 a month per user.

Migrating to Unified communications exchange 2007

we are currently using unity 5.0 and it is in its own active directory domain and forest as well as the exchange 2003..we want to move to exchange 2007 unified communications and this is in a different domain/forest as well...what would be the proper steps to migrate over in a situation like this from untiy 5.0 in one seperate forest than exchange 2007 thats in another forest?

Hi,
This is really more of an MS question.
But I take it you are using Unity VM only for exchange? If it is a separate AD then the only info in that AD is used for Unity so you dont really need to keep any of it.
If it's in a separate AD then why not just configure your exchange 2007 for UM in parallel.
In CallManager you can configure a separate voicemail profile for Exch UM and assign it to certain users.
Have you piloted this yet? There are some limitations with UM for Exch 2007.
You can export subscriber information from SQL database on unity, and use it with powershell script for exch 2007 to actually get the users across.
I'd say when people move, they are going to have to re-record greetings, and lose their old voicemail etc.
Cheers,
Tim

Migrating from FirstClass to Exchange

This message is for the very few out there who will be migrating from FirstClass server to Exchange.
I created a VB Script that will convert exported messages from FirstClass into a comma delimited file (CSV) that can be imported into Exchange.
FirstClass is not a full featured IMAP server, and thus you cannot migrate Sent emails or emails in folders using the Transporter Suite.
If you have any questions, feel free to contact me: [email protected]
Enjoy,
John Dombrowski
I cannot attach a file, so here is the code:
'VB Script to convert Exported FirstClass emails to comma delimated files
'Written by John Dombrowski - Thornapple Kellogg Schools - [email protected]
'Instructions:
'1. Create a Folder on your desktop called 'emails'
'2. Save this file into that folder the folder
'3. Create two (2) files inside the emails folder:
' 1. convertedfinal.csv
' a. Open this file and add the following line: "From","Date","To","Subject","Body"
' 2. temp.txt (you can leave this file blank)
'4. Create a Folder inside the emails folder called 'Exported'
'5. Export your FirstClass Mailbox, Folders, or Individual Emails into the folder created in step 4
'6. Run the convertemails.vbs file
'7. If everything ran properly, the convertedfinal.csv file will contain all of the emails that you exported in a
' comma delimeted file that can then be imported into other email systems.

Migrating From IMAP to Exchange 2013

Hi
I'm looking to migrate from a hosted imap email provider to racked exchange server 2013
we have about users, but also some of the services we provide generate and send mail
We are looking to just migrate the users for now, but at the risk of sounding stupid, I don't think this is possible due to the domain and the mx records, as in we don't want to change the email address' and we would be able to have both hosted and in house,
using the same domain
Any help and advice is very much appreciated

Do you have access to hosted environment to move the mailboxes?
What is the number of users you are talking about?
To move the mailbox you would require some third party tool.

Migration from OCS to Exchange 5.5

Hi All,
I need to migrate the users and thier email addresses and thier inbox into new exchange 5.5 server, is there any tool to do that, or any way!!???
Best Regards

OCS uses IMAP4 for storing emails, so the best thing would probably be to ask on some Microsoft message board about the best way to migrate from IMAP4 -> Exchange.

Migrating from Shared/Hosted Exchange 2010 to Onsite Exchange 2013

Hi All,
Hoping for some advice regarding a migration project I'm due to run with. A client has their current email data with a 3rd party hosted Exchange platform, this is a completely separate platform from their onsite AD infrastructure.
Platform wise it is built on Exchange 2010 that only really allows OWA/Outlook Anywhere/ActiveSync access. We'd like to migrate this platform to a more dedicated onsite Exchange 2013 platform.
Any software tools or advice appreciated, we're hoping to avoid exporting all the content to PST and manually importing but if this is the only way then fair enough. If there are utilities that may allow mailbox backfilling to suck the data out and in to
the new mailboxes in 2013 that would be awesome.
Thanks in advance!

Hi,
According to your description, my understanding is that you want to migrate mailboxes from the other forest to your forest.
I recommend you refer to the following article to achieve migration:

Hope this helps!
Thanks.

Migration from Rackspace to Exchange Online

I am having an astoundingly hard time migrating one test email address (mine) from our current rackspace email address to my new exchange online. When I use the migration tool, I give it the 2 line CSV file (headers and 1 line of my address) and start the
migration it just hangs for a couple of minutes trying to authenticate, I assume to the rackspace server.
Maybe I dont have the right rackspace server name but I have tried rackspace.com, cp.rackspace.com, apps.rackspace.com and email.rackspace.com. My users use apps.rackspace.com to login to their email. I use cp.rackspace.com to get the control panel. I have
seen them called email.rackspace .com and I threw in rackspace.com for good measure. When I login at apps... I use
[email protected] as the login id. When I login to cp.... I use only rpierce.
I have tried many cominations of server addesses, login ids etc. and I always die in "Connecting and Authenticating to source server". Does anybody have any ideas here?

I realize this is a very old posting, but I just went through this migration process this weekend and wanted to share for future posterity.
So, if you want, you can use the Microsoft Exchange EAC Migration tool to migrate over your email from Rackspace. It worked fairly well - HOWEVER, it is only email and not your contacts or calendar, which for us was not good. If you still want to do this,
here's how:
1) Go to the EAC Migration.
2) Add - Migrate to exchange online
3) For pretty much any hosted exchange system, you're probably not going to be able to do nice migrations like Cutover. Instead, you're stuck with IMAP...which is also why you can only do your email and not calendar. Companies like Rackspace will not give
you enough access to do Cutover migrations.
4) Upload your CSV file.
5) For your IMAP server, type in your mail server. If you do not know it, you should be able to get it from Outlook. Go to your Account Settings. To get the proper server, you may need to go to "More Settings", Connection, Exchange Proxy Settings,
and copy the proxy server name. For our Rackspace server, it was mex07a.emailsrvr.com
5) Name the migration and start it off.
Ok, so that does JUST email, but NOT calendar and contacts. We needed that. So, after a lot of hunting around and finding a couple of posts that helped, the only real option was migrationwiz.bittitan.com . It does cost about $11.99 an account, but it did
a good job. You can setup trials and run free migrations which migrate a few emails/calendar/contacts as a test.
When setting up the migration project, their system allows you to type in the source/destination servers, or they have a "I know my service provider" option. I clicked on that and was able to find the desired Rackspace server in the list.
Everything went real well, EXCEPT stupid me had done the IMAP migration and then the MigrationWiz. All emails wound up being duplicated. MigrationWiz keeps track of what it migrates and does not duplicate, but since I had all of the emails in the destination
already and then did it again, I duplicated everything. I wound up having to switch to the "Classic" interface for MigrationWiz, selecting all accounts, clicking on Bulk Options > reset mailboxes, and reset the statistics and errors for all accounts.
Then I had to clear everyone's email accounts out of mail. Again, problem - DNS was already pointed to new server, so I literally had to go into everyone's account on OWA and delete off all emails that were before the DNS change. UGH. Then I went
back to MigrationWiz and started their migrations over. So, much of that would not have been necessary if I didn't migrate with two different tools and if I had waited to switch DNS.

Migration from IMAP to Exchange online

Got a little pickle going on here:We've purchased Exchange online as we were rather dissatisfied with our email provider. In migrating over, I've updated our MX records, but when Exchange tries to "find" them, the address is incorrect (mydomain-com.mail.protection.outlook.com.mydomain.com).Exchange is telling me it should be mydomain-com.mail.protection.outlook.com and that I should change that before it will work. The same issue is coming up for all my records as Exchange sees them (with the extra .mydomain.com added at the end.Our domain is registered through network solutions, but our hosting is done through this other company, and they are also hosting our website. I wanted to stick with them for the web hosting because there have been few to no issues on that side.Has anyone seen this before?

After Exchange 2007 Migration to Exchange 2010, OAB is erroring

Hello all,
I migrated from single server Exchange 2007 to single Exchange 2010 2 months ago using a co-existence environment. The 2007 server is still running, but it's not doing anything but SMTP relay, as I am waiting on Oracle admin to point their server at
my new 2010 server. Yesterday, I noticed a new mail enabled user we created was not showing up in the Address Book. He is in the Global Address list when I check it from OWA. And I can see him in my Address book if I search All Users,
instead of the Global Address List. Everytime I try to update the Offline Address Book, I get the following error
OABGen encountered error 80004005 while cleaning the offline address list public folders under /o=2007Server/cn=addrlists/cn=oabs/cn=Default Offline Address Book. Please make sure the public folder database is mounted and replicas exist of the offline
address list folders. No offline address lists have been generated. Please check the event log for more information.
- \Default Offline Address Book
There was a Public Folder on the 2007 server, but I don't think anyone was using it. All of our clients our 2007 or later. Enable Web-based distribution is enabled and Generation server is my new 2010 server. Enable public folder distribution
not enabled.
Any help would be greatly appreciated.

No, the Enable public folder check box is not ticked. However, the link you provided has led me to other clues. The author says "To locate the actual
OAB distribution point on the Client Access Server, the Outlook client will use the autodiscover service." I wonder if still having the CAS role on the old 2007 Exchange Server still installed is causing issues with Autodiscover. Below

Public Folder Migration - disable on-premise?

I am in the middle of migrating Public Folders from on premise Exchange 2007 to Office 365.The mail-enabled switch and email addresses are not being transferred. I can use powershell to mail-enable the O365 PF's, but that is giving them an address with [email protected], and I want to continue to use the same email addresses they had before - [email protected] found a script that grabbed all the on-premise PF email addresses, but when I try to add them to the O365 PF's I get an error saying the email address is already in use:TextThe proxy address "smtp:[email protected]" is already being used by the proxy addresses or LegacyExchangeDN of "ABC".

Hi James
Check for illegal characters, spaces and trailing spaces. I have had similar problems with this in the
past.Also it can be a problem with the mail enabled public folders as well.For mail enabled public folders alone go to PFMC click mail disable and then try to migrate them and see the results.
You can try disabling and re-enabling the mail-enabled public folders and see the results.
Also you need to remove the legacy public system folders, like StoreEvents{GUID}, OWAscratchpad{GUID}
etc, before you can migrate the public folders to Exchange 2013

OWA still redirects to Exchange 2007 (legacy) after mailbox-move to Exchange 2013

Hi,
I am in the process of implementing Exchange 2013 in coex with 2007. I am testing now in a copy of the production environment and have installed the Exchange 2007 SP3 RU11 prior to installing Exchange 2013 using the SP1 media.
We use a wildcard certificate and I prepared the Exchange 2007 internal/external URLs for OWA/OAB/etc to use the legacy.domain.com names and in Exchange 2013 I set them all to email.domain.com. Exchange 2013 has Outlook Anywhere configured.
All tests like autodiscover (internally via SCP) run fine and for a new Exchange 2013 mailbox the Outlook and OWA functionality is as expected. A mailbox still on 2007 also connects fine via Outlook and while connecting to OWA (using the htps://email.domain.com/owa
url) also redirects me to https://legacy.domain.com/owa just fine.
HOWEVER: after a successfull mailbox-move from 2007 to 2013 my OWA logon-request STILL get's redirected to the 2007 legacy URL. When I then logon again on the 2007 OWA I get the message that I should connect to the 2013 URL and end-up in a loop.
Anyone any tips where to search?
Many thanks in advance.
Best regards and many thanks in advance, Eric Vegter

This seems to be an outstanding issue.
We just performed a fresh install of Exchange 2013 on a Windows Server 2012 R2 operating system. We're migrating from our existing Exchange 2007 server. At the moment we have everything properly setup in a co-existence state. All we lack is to complete the
migration of our mailboxes from the 2007 DB to the 2013 DB.
In performing the first mailbox move, to test the migration process and make certain mail flows as expected, we noticed this same problem. Before reading through this thread, I was able to assign Full Access to a delegate user and then perform the "Open
Mailbox" feature from a 2013 user's account. This was successful in opening the mailbox within OWA 2013. However, I still could not access the account by simply logging into the Outlook Web App. It would login, then proxy back to OWA 2007 with the message,
"Use the following link to open this mailbox with optimal performance:
http://mail.domainname.com/"
After reading about cycling the OWA app pool, I immediately tried it as a workaround and it worked. It is a little frustrating going about it in this way. Hoping to see more activity on this thread.
