Exchange 2003 Exchange 2010 migration confusing?

Hi,
I have searched several articles for this migration in this forum and other forums (ie
petenetlive,
simple-talk,
Exchange Server Deployment Assistant,
Technet) but when you start reading the guides there are discrepancies between one and the others and vice versa.
I have this scenario:
1) Old server windows 2003 R2 std + exchange 2003
2) New server windows 2012 R2 + exchange 2010
I have not installed exchange 2010 yet because I had to first update Active Directory schema to W2012 (adprep /forestprep, adprep /domainprep) R2 and also update exchange schema using setup /PrepareSchema from the exchange 2010 media.
Then I read that I have to install Exchange 2010 in stages ie Client Access Role first, then Transport Hub and then Mailbox role.
Also a digital certificate i required and was wondering if I could still use a self signed certificate.
Does anyone know of a very good article or video that explains this process consistently STEP by STEP?
Thanks

Exchange 2003 to 2010 Migration and Certificate Issue

Good Day All -
This is my first post on here, so if I post to the wrong spot or something is incorrect, please forgive and redirect me.
I have a small working knowledge of Exchange and even less about Certificates.
I did an Exchange 2003 to Exchange 2010 migration last weekend, and, for the most part, everything went well. Initially when users first launched Outlook for the first time, (post mailbox move), the received a Security Alert to install the Self-Signed
Certificate for the new Exchange Server. This was a one time deal and everything was good after that. Also, I exported the non-self-signed certificate, (for external mail, purchased from Network Solutions), from the Exchange 2003 Server, and imported
it into the Exchange 2010 Server. Again, no issue.
Jump ahead to today. It was brought to my attention that some mobile devices were unable to connect, and in my infinite wisdom ,<sarcasm>, I thought the issue had to do with the certificate(s). I started troubleshooting and it seems like I've
fixed the the mobile devices being able to connect, but now every time users launch Outlook, they receive the Security Alert for the non-self-signed certificate, over and over again. (or it just pops up while connected to Outlook)
They go through the motions of installing it, but it just keeps coming back.
I have referenced several articles on here, and other sites, but nothing has worked and I'm stuck and fried on this one.
http://support.microsoft.com/kb/940726/en-us
http://exchangeserverpro.com/how-to-issue-a-san-certificate-to-exchange-server-2010-from-a-private-certificate-authority/
Would someone please help. Thanks very much, (in advance).

Thanks for the reply. Yeah, I have read many articles, (especially from exchangeserverpro), and have learned alot, but I am definitely a cert novice here.
The cert "error" on my internal Outlook Clients is a Security Alert for
mylocalservername.mydomain.lcl. When I click to view this certificate it points to
webmail.mydomain.com, which is what the external
devices use for SSL verificartion.
I'm not understanding why my internal Outlook clients are prompting for this external certificate.
I have the self signed certificate that auto-installed with Exchange 2010, which points to the DNS Names:
mylocalservername.mydomain.lcl and mylocalservername. This was the server certificate that the Outlook clients installed after they launched Outlook post mailbox migration to the new Exchange
2010 server and everything was good internally.
For my external connection then, I exported the webmail.mydomain.com
from the old Exchange 2003 server, and imported it on the new Exchange 2010 server; (EMC\Server Configuration\Import Exchange Certificate (Actions Pane)). Ever since doing this, all Outlook clients, (2007 & 2010)
receive the Security Alert for mylocalservername.mydomain.lcl, but is for the
webmail.mydomain.com cert.
I have two certs on the Exchange 2010 server; one self signed and one not, (The non-self-signed purchased from a CA and thus the one I imported from Exchange 2k3).
The services assigned to the two certs are:
Self-Signed, (mylocalservername.mylocaldomain.lcl and
myservername):
IMAP, POP, SMTP
Non-Self-Signed, (webmail.mydomain.com, Purchased from CA)
IIS
Please let me know if there's anything glaring here that I'm missing, and if not, what you think the problem may be. Thanks very much.

Exchange 2003 to 2010 Migration

Hello,
I seem to have ran into issues with Default GAL, default address lists, email address policies, OAB, etc.
Background: Exchange 2003, with one FE and one BE server with multiple domains for mail access. We decided to migrate to 2010 and have one hyper-v server with 3 VMS running AD, CAS/HT and MBX roles respectively. All the AD preparations and installation (exchange
2010 Sp2) of CAS/HT role was smooth. When I installed the MBX role it was successful but could not see Public Folder Database and was unable to create one because of AddressList errors and had to be upgraded to 2010. Since there were multiple domains, LDAP
filter were used and those had to be updated with OPATH filters and I used the "ConvertFrom-LdapFilter.ps1" script to convert and upgrade to 2010. I could do this for all the custom address lists but it did not run for "All Users", "All
Groups" "All Contacts" as it says ADObject cannot be found on exchange2003 server.
I created a test mailbox on the new server and could login using OWA but cannot see GAL or search for addresses. I could send and receive email from 2010 to both 2003 mailbox & external domain with no issues. I did configure the CAS role with legacy
URL (existing OWA URL https://myweb.domain.net/exchange) for exchange2003 and a new URL (https://mymail.domain.net/owa) for exchange 2010 and also enabled Outlook Anywhere, MS Active Sync, etc. But I cannot setup outlook using autodiscover or even manually
by providing the info. I have to start migrating users and this has become a big show stopper and would appreciate if anyone could help/guide me through this to troubleshoot/fix the issues and move the mailboxes ASAP.
Some errors:

Hi SyedSF,
From your problem description, it seems that you have a permission problem here. Maybe you have had Address List Segregation configured in Exchange 2003 and that is not supported in Exchange 2010.
I recommend you to use ADSIEdit to check the permissions on "All Address Lists", "All Global Address Lists" and "Offline Address Lists". Include inherited permissions should be checked and "Authenticated Users" should have the permissions read and "Open
address list".
What's more, here are some similar threads for your reference.

Exchange 2003 to 2010 migration move public folder

Hello.
I'm on the road to Exchange 2010 migration and stuck at on question
All tutorial says then you want to replicate system PF and Public Folders you need to add PF 2010 in ESM and set replication to Urgent,that's all
But then i view my system PF replication on Exchange 2010 i see checkbox Use public folder is checked and replication shedule on Exchange 2010 is set to Never run(greyed out)
Is this right? Or i need to uncheck it and then shedule is set to Always run automaticly?
Do i need to do it for all PF? (system and non-system)?

Hi stevemaystr,
Don’t worry about the replication of PF, we can use the MoveAllReplicas.ps1 and ReplaceReplicaOnPFRecursive.ps1 script to move all public folder and all replicas to another database, please refer to:
http://technet.microsoft.com/en-us/library/bb331970(v=exchg.141).aspx
Additional, I find an similar thread about Migrate PF from Exchange 2003 to Exchange 2010, for your reference:

Exchange 2003 to 2010 migration mailflow issue

Hello,
I have a server 2003 w/ exchange 2003 that we are upgrading to 2010 to support Outlook 2013.
So we installed a windows 2008 server and exchange 2010. We followed a guide to help with the different steps and didn't have problem or error until now.
So what we have right now, is exchange 2003 with still ALL mailboxes.
Replications of folders is done.
Policies are updated.
The firewall is forwarding port 25 to the new exchange 2010 server:
Emails are coming in fine.
Internal emails are also perfectly fine (from internal user to internal users).
the only thing that is giving us trouble is the emails coming out. None of them are going out and they are getting "stuck" in the "routing group connector" on the 2003 machine.
The 2010 exchange has a simple send connector set SMTP/* with this server as source. The 2003 exchange only had the exch2003-exch2010 connector.
Because emails were kind of accumulating (80+) I decided to take the send connector on the 2010 exchange out. and added back a send connector on the 2003 exchange. This kind of "fixed" it as now all emails are going just fine. It also fixed
the queue as part of it got liberated when I added the 2003 send connector.
I still have 25 emails stuck in this "routing group connector" that I'd like to take care of.
We are obviously not done with the migration and this coexistence phase as actual mailboxes still need to be moved.
So I'd like to take care of this queue in the routing group connector as well as continue the process of being able to receive and send from the 2010 machine only. then I would continue the migration process.
FYI, the 2003-2010 connector was created using power shell on the 2010 machine. I am not using any smarthost.
and the error message (in the queue) I get is: "unable to bind to the destination server in DNS"
FYI, my 2003 server is called "SERVER1" and the 2010 server is "SERVER2", they're on the same local domain company.local.
FYI (not sure if that's relevant), the server1 exchange has a different certificate (different domain name) than the new server (server2) as our web host finally allowed us to use subdomains. not trying to confuse anyone but I am really stuck there and maybe
this is related: certificate for the exchange 2003 machine: www.company-mail.com (only 1) and certificates for the exchange 2010 are: mail.company.com / autodiscover.company.com (and a legacy.company.com we may not need since the actual coexistence phase will/should
be short).
any idea what's wrong here?

I added back the send connector on the 2010 exchange. everything still works fine since I still have the send connector on the 2003. However...
I connected through telnet to server2 (the exchange 2010) and was able to mail internally. however I couldn't send mail externally, it gives me a "cannot relay" error when I enter my rcpt to:... command.
I am guessing that this may be the reason why the queue is not emptying itself through that send connector.
Anything else I could try to test my "send connector" on the 2010 exchange?

Case of the Missing User Exchange 2003 - Exchange 2010 Migration issue

Hey All,
I am in the middle migrating from Exchange 2003 to Exchange 2013 by way of Exchange 2010 and going through the final parts of my Exchange 2010 portion of the migration I found that one of the users on Exchange 2003 is not showing up in the EMC to migrate.
In EPS I can find the user with Get-User username but I cannot get the mailbox or kick off the mailbox move from EPS giving me the error of "Object could not be found" It is a valid user with a valid user mailbox and I can log into the
mailbox in OWA for Exchange 2003. Any thoughts as to why the user's mailbox is not showing in EMC or that I can't get it to move via PS?
Thanks,
Joe

Exchange 2003 to 2010 Migration OAB Generation Issue

Hi
I am in the process of migrating from 2003 to 2010. All mailboxes are moved across and email in and out are moving through the 2010. However I cannot move the oab generation server as when i go to change the generating server my New 2010 server is not listed
only the two old 2003 servers. This is a child domain in a large organization and is one of a large number of exchange servers forestwide. I have created a new oab and asigned to the mailboxes on the new 2010 server. The old 2003 server is off for over a week
and there are no issues.
I now need to remove both 2003 servers, what issues will not being able to move the generation server cause (If any if i am using a new oab). Also I am following the remove last exchange server line as this is the last 2003 server in this child domain are
there any issues with this in this scenario?

Hi,
According to your description, I understand that all mailboxes have been moved to Exchange 2010 and a new OAB is created for all users in your environment.
Please make sure the new created OAB is generated by Exchange 2010 and Enabled Web-based distribution. If there are any Outlook 2003 users in your environment, the public folder distribution should also be enabled. Then we can set the new one as default.
If so, all users in Exchange 2010 would use the new created OAB by default.
If you want to double check the OAB configuration, we can run the following command to check it:
Get-OfflineAddressBook | FL
Additionally, if your migration is complete and successful, we can follow the article below to remove the last legacy Exchange server from your Exchange 2010 organization:

Setting up a test AD domain to practice Exchange Server 2003 to 2010 migration

Please critique my plan to upgrade our Exch 2003 server to 2010.
I want to start by setting up a test domain using an old Win Svr 2003 DC, and another old win 2003 server as an Exch 2003 mail server.
This test domain will be connected to our existing LAN so I need to make sure it doesn’t cause any problems.
We are a small single domain shop with a public domain name that I will call “mycompany.net” for the purposes of this question.
Our DC’s are named: “dc05.main.mycompany.net”, “dc06.main.mycompany.net”
Mail server: “mail1.main.mycompany.net”
Public DNS for our domain has an MX record that points to a public IP we use for our Sonicwall spam filter. The firewall has a 1 to 1 NAT entry to route that public IP to the LAN IP of the spam filter with corresponding rule that allows smtp to that LAN
IP.
The spam filter routes good mail to the Exch Svr, and the Exch Svr uses the spam filter as a smart host for outgoing mail.
Another public DNS entry points “smtp.mycompany.net” to our firewall which 1 to 1 NAT’s that public IP to another LAN IP of our Exch Svr (we have 2 IP’s assigned to this server). This is used for OWA, ActiveSync etc. to the Exch Svr.
Test Domain Setup
I plan to name the test domain “test.mycompany.net”.
DC = “dc01.test.mycompany.net”
Mail = “mail.test.mycompany.net”
Public DNS MX record for “test.mycompany.net” to point to a currently unused public IP we have available.
MX record for “test.mycompany.net” will point to public IP x.x.x.10
Firewall will NAT that public IP to the LAN IP x.x.x.30, and allow smtp on that IP to route to the sonicwall spam filter.
The spam filter will have in incoming mail path setup that routes mail with source IP x.x.x.30 to the test mail server.
Outgoing mail configuration on the test mail server will be the same as the “main” exch svr I guess.
Once the test domain seems to be working:
I will obtain an SSL certificate (we are not using SSL now) and apply it to the test mail server, so I can figure out how that works.
Then I will add a new Win Svr 2008 R2, Exch Svr 2010 machine to the test domain and go thru the procedure of migrating to it.
Once I feel like I know what I am doing I will plan the migration of the “main” domain mail server.
Primary concern is to not allow this testing to disrupt the operation of our currrent systems.
I know this is a lot to ask, but I’m hoping some of you guys just love this stuff so much you will enjoy thinking about it and helping me with any constructive suggestions.
Thank you.

Upgrade Custom Recipient Policies as part of Exchange 2003 to 2010 Migration

Hello,
We have Exchange 2003 and Exchange 2010 in co-existence. I have migrated all Mailboxes to Exchange 2010. Now I want to upgrade Recipient Policies.
We have 1 Default Policy, which I know how to upgrade
Set-EmailAddressPolicy "Default Policy" -IncludedRecipients AllReipients.
But my I dont know how to do it for 2 other Custom Policies. I came to know about the conversion scripts (http://technet.microsoft.com/en-us/library/dd351283.aspx)
but not sure how to run. I mean simply run the script on Exchange 2010 server or any special parameters needs to be included.
I can let you know the custom policies if required.
Thanks,
Mihir

Hello Niko,
I have already gone through this article, but it states for the "Default Policy". For custom policy it says
"Warning:
if you happen to do this on Recipient Policies that have (advanced) LDAP queries, all custom filters can be reset to "mailnickname=*"
which can result significant email outages. You have to test all these changes in a dedicated lab environment to see how these changes will affect your Exchange environment!"
I want to know about Custom Receipient Policies, not the Address list.
Custom Policy 1
(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=contact))(objectCategory=group)(objectCategory=publicFolder)(objectCategory=msExchDynamicDistributionList)
Custom Policy 2
(&(ou>="")(name=DOMAINNAME*))
Custom Policy 3
(&(mailNickname=*)(legacyExchangeDN=/O=NAME/OU=OURNAME/*))
So how to convert this custom policies.
Thanks,
Mihir

Exchange 2003 to Exchange 2010 Migration

Is there anything I have to do to migrate Exchange 2003 to Exchange 2010 aside from migrating the database(s)? I believe autodiscover picks up the new server when people open Outlook?

It will definitely HELP
you with the migration process, its not a guaranty for a successful one.
You should be familiar with both systems (Exchange 2003 & 2010) and know the migration process and be familiar with each step .
Best practice is to make the migration in lab environment that is a copy of you production environment first. that way you will get an experience with the process and know in advance if there are any issues before go to production. I
know that in real world this is not always possible.
Here is another grate guide from Pete Long:
http://www.petenetlive.com/KB/Article/0000234.htm
As a side note, Exchange SP1 or SP2 no longer supported, so make sure your Exchange 2010 is installed with minimum SP3 (RU5 is better).
Please take a moment to Vote as Helpful and/or Mark as Answer where applicable. Thanks.

Exchange 2003 to 2010 Migration - Offline / Address List conversion

I have seen several articles on the above but my question is this:-
Q/
Can I carry out the above before I move all the Exchange 2003 mailboxes over, or should this be only done once all the mailboxes have been migrated to the new server?

Hi,
It is recommended to migrate mailboxes at first. If your mailboxes have been moved successfully, you can move your offline address book.
What's more, here is a thread for your reference.

Exchange 2003 to 2010 migration web-mail question?

We are in the process of migrating our Exchange 2003 server onto Exchange 2010 and I have produced a plan to achieve this, but would appreciate some help regarding a couple of steps? In particular how this will affect external users. Information:At present we are running windows 2003 Domain controllers which I will be updating to the levels required for Exchange 2010 to exist.Our Email is provided by an external company which sends the mail to our external IP address on the firewall, which in turn is forwarded to the internal IP of the current exchange server.

Exchange 2003 to 2010 Migration Active-Sync & OWA

I am in the process of migrating from Exchange 2003 to Exchange 2010. I have a co-existence running currently. I have moved 1 mail box over to the new exchange server (a test account I created). I have 2 questions, one about OWA and the other about Active-Sync/Mobile
access.
1. When I log into my internal OWA site I can access the webmail just fine. However when I try to go to my external OWA site I get a HTTP Error 404. I have setup the weblink https://webmail.company.com in my external DNS record. However the internal link
says it is https://webmail.company.com/owa. Is there something additional that needs to be setup in IIS for the external site to work or only after the migration is completed?
2. I tried adding the account I migrated to my cell phone for mail but I just get a "Connection to server has failed" message. The internal and external link for mobile access is both the same and setup in external DNS https://mail.comapny.com.
Is this a feature that only works after the migration is completed? I have ports 80,443,143,25,993 open in my sonicwall for e-mail services. However the IP is still set to my old exchange server. Is it possible to have 2 settings the same in sonicwall with
2 different IP's? Last time I tried it with migrating my VPN neither VPN server worked after that.
Any help and insight would be greatly appreciated. I am new to systems administration and this is my first exchange migration

Hi,
Here are my answers you can refer to :
1. To deploy OWA in the Exchange 2003 and 2010 coexistence, we need a legacy namespace for the Exchange 2003 server.
For more information, you can refer to the following article:
http://blogs.technet.com/b/exchange/archive/2009/12/02/3408921.aspx
Additionally, for the 404 error, I recommend you check the IIS log to find the root cause:
http://support.microsoft.com/kb/943891
2. I recommend you deploy Exchange 2010 in the "Internet Facing AD Site" and Exchange 2003 server in the "Non-Internet facing AD site": set the external URL in CAS 2010 and point mail.company.com to Exchange 2010 server IP address.
For more information, you can refer to the following article:

Error in uninstall Exchange 2003 after Exchange 2010 migration.

Setup encountered an error while checking prerequisites for component "Microsoft Exchange": 0X80072030 (8240): There is no such object on the server. I searched about the error and most of the hit is referring to postmaster account point
to the old server and that doesn't apply to our environment.
http://support.microsoft.com/kb/283089
below is the errors from the setup log. Other users had reported this problem but didn't find any solution other than manually uninstall the last Exchange 2003 server.  The problem is I couldn't find any official KB for manually
remove legacy Exchange server from Exchange 2010 org, bb288905 or kb833396 do not provide enough information. So is my only choice is to call Microsoft Support?
thanks

Did you also check for other accounts, i.e. non-postmaster?
Setup will check to make sure that there are no mailboxes homed onto this server.    This attribute homeMDB could still be set for a mailbox that has the Exchange attributes remove. Seen that before when people set attributes directly
via scripts.....

Yes, I did. Nothing has MDB = the legacy server.    The error from setup log seems to suggest a different problem.

Exchange 2003 Exchange 2010 migration confusing?
