Migration from 1 domain to another (in relation to Exchange)

Hi, hoping someone can give me an opinion on the best way to carry out this task as it's quite a big project. I've read various articles on technet and other blogs, but I'm not sure if this is even possible with the versions of Exchange involved. Details
below:
We are carrying out a domain centralisation project - merging from an external forest (Domain B for example purposes) into another Forest (target Domain A). I will be using ADMT to carry out the account, group migrations etc and will include SID history
when doing so.
There is a two way external trust between the domains.
Domain B (source domain) has it's own Exchange 2010 environment. The target domain is on Exchange 2003 SP2.
Once I have migrated the accounts, is there any Exchange tools or methods for me to ensure that the migrated accounts can still access their Exchange mailboxes (with the domain trust still in place)?
As mentioned earlier I will be migrating SID history to ensure no disruption with access to resources, I have read that this would also be needed to ensure users can still access their original mailboxes in the source domain. Eventually we will be migrating
the mailboxes from old domain to new but this is phase 2 of the project (either by PST import or however this can be done, that will need to be thought about later...).
Any advice on how I can make sure the migrated users can still access their mailboxes and what I need to do, would be much appreciated.
Thanks,
Sarah

If the target forest is running Exchange 2003, you aren't 100% wrong in saying it may not be possible. If you are migrating from Exchange 2010 to a new forest, you need to be migrating into an Exchange 2010 organization - downlevel migrations aren't supported,
to the best of my knowledge. Here are the links supporting Exchange forest migrations, and they specifically say they are for migrations into an Exchange 2010 organization:

http://technet.microsoft.com/en-us/library/dd876952.aspx
I'm pretty sure that the tools used won't allow you to migrate from Exchange 2010 into Exchange 2003. I'm sure you can kludge together a migration process that exports mailboxes to PST, then imports them into the target mailboxes, but that would be
a painful process.

Exchange Migration from One domain to another domain on same forest

Team,
we are in the process of migrating exchange infrastructure from one child domain to another child domain within same forest.
root domain - root.com
child domains - US.root.com and EMEA.root.com
EMEA and US Domains setup are different from each other. Like EMEA has different email address policy , Email Flow than US , connectors etc.
Now we need to migrate all emea users under US Domain. based on the geographical locations, we are building a new dc, mailbox , cas servers on EMEA location , but these servers will be part of US Domain.
for CAS Servers - we are planing to register respective sites ( site affinity), so all the local requests will be handled by new cas server which is built under US Domain.
Mailbox Servers - we would be creating new db's and the limits on new mbx server and going to replicate as its on EMEA Mailbox server.
can some one please let us know what are the precautions , recommendation, sequence which we need to follow to perform smoother migration. as of now , I can think of below topics.
Mailbox Migration -I Have a script , which
will take care of mailbox movement once the objects are being moved.
Contacts Migration - Willard Martin blog helped me to perform migration
DL Migration - I believe there is no mechanism to migrate DL. only option is to recreate.
Email address Policy:we would be creating a new address policy and apply to OU's
DB Consistency check – do we have to perform the health checks on source mailbox server to see , the servers are free from errors /corruption.
Check outlook configuration - After the migration, we need to check and see , the exchange server/ auto discover works and identify the new exchange servers.
Internal /External Email flow.-
Active Sybc , OWA
Public folder Migration -
Offline Address Book
Certificates
any help or suggestions would be great.

AD Migration from one domain to another domain between different Forest.

Dear Team,
We have a domain named "test.gov.in" .Now we want migrate all the users,computers,groups,GP ....etc in to our new domain "abc.net".Operating system of the source DC and destination Dc is same (Windows 2003 32 bit)..
Pls provide me the steps to migrate one domain to another domain between different forest
Thanks
Anurag

Would agree with Christoffer and migrate using ADFS but before you can do this you will need to set up a trust between the two domains. Once this has been accomplished then you can run ADMT.

File associations are lost when user account is migrated from one domain to another domain (SID changes)

Hello,
Currently we are in the middle of a migration project. We are migrating users from child domains to the root domain of one organization.
The user accounts are migrated with powershell using Move-ADObject cmdlet. This works as expected. The SIDHistory attribute is updated correctly.
Recently we received complaints from some *migrated* users - they lost their default/custom file associations. This happens only on Windows 8/Windows 8.1.
What happens:
the user is migrated and logs on
her profile loads and everything's preserved (as expected)
the user clicks on a .jpeg file (previously associated with program XYZ)
OS asks the user to choose a program to open the file with
the user chooses a default program XYZ and the file opens
when the user clicks on a .jpeg file again - OS asks to choose a program again
i.e. the settings are not preserved.
Our investigation shows that it is connected with the UserChoice registry key and the HASH value under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.SomeExt
According to this blog
the HASH is calculated based on user's SID. But after the migration the user has new SID and the HASH becomes invalid and we hit this:
"However In Win 8, the registry changes are verified by a hash (unique per user and app) that detects tampering by apps. In the absence of a valid hash, we ignore the default in the registry."
Currently deleting the UserChoice key for all associations solves the problem. But the user has to make all her customizations again which is undesirable.
Is there any supported way to fix this? Why the OS doesn't update the HASH after the first logon when the SID has changed as it updates the SID for the ProfileList key?
This could become big issue in large migrations.

Hello Petar K. Georgiev,
Please check the following article to change the registry key to change back to the default file type associations.

How to migrate Distribution list from one domain to another within same forest

team,
we are in the process of migrating all users mailbox, DL and contacts from one domain to another within a same forest.
can some one please let me know how can we migrate them without loosing the group membership and exchange attributes.
Kindly help.
Srinivasa K

I ran all of them
First Command , it works very well and its removed the exchange attribute
$DomCtrlr = (Dir env:Log*).Value.Replace('\','')
Get-MailContact -OrganizationalUnit Contacts -DomainController $DomCtrlr | Export-Csv E:\MailContacts.csv
Get-Contact -OrganizationalUnit Contacts -DomainController $DomCtrlr | Export-Csv E:\UserContacts.csv
Import-Csv MailContacts.csv | Disable-MailContact -DomainController $DomCtrlr
Second command
$DomCtrlr = "DCNAME"
$MailContacts = Import-Csv E:\MailContacts.csv
$UserContacts = Import-Csv E:\UserContacts.csv
after running the above command, I copied below on note pad and saved as .PS1 , as per your advise I make sure that starting with new-mailcontact and below 2 are is same line and Executed the ps1 script.
Scipt rans but didnt give me any error mesage.
ForEach ($Contact in $MailContacts) {
    $UserContacts | ? { $_.SamAccountName -eq $Contact.Alias } | % {
        New-MailContact -DomainController $DomCtrlr -LastName $_.LastName -FirstName $_.FirstName -Alias $_.SamAccountName -DisplayName $_.DisplayName -Name $_.Name -ExternalEmailAddress $Contact.ExternalEmailAddress -OrganizationalUnit
Test_con }
By Running
$MailContacts : it provided the stored value for users
$UserContacts: it
provided the stored value for users
after runing below in single notepad as .ps1 , not getting error message , but its not giving any
output nor error.
suspecting something needs to b checked on for loop
ForEach ($Contact in $MailContacts) {
    $UserContacts | ? { $_.SamAccountName -eq $Contact.Alias } | % {
        $_
Hope this explained clearly.

How can I migrate from one user to another within the same computer?

My main user account in my desktop is becoming buggy after to many migrations from different computers and long time usage. I would like to migrate from one user to another user within the same computer to see if this improves my current problems.
How can I do it in a reasonably safe and quick way?
Thank you very much, cheers, Rui
iMAC, OS 10.6.8... and yes, I love Snow Leopard light and handy... and all my programs work on it...

Move small groups of files to the /Users/Shared/ folder or another location and see if the problems disappear. Moving everything to a new user account will in all probability transfer the problems.

Setups migration from one instance to another

Can any one please tell me how to migrate AME (Oracle Approval Management) setups and GL Setups?
We are using AME.B.(11.5.10.2). There will be quite a few of these setups required, and migrating by hand in all the eBS instances will be difficult.
Is there any other way (API/other tools) to achieve this? Can we use FNDLOAD?
Thanks in advance,

Hi Anugrah,
Unfortunately there isn't a facility to allow a customer iStore site to migrate from one environment to another (e.g. Test to Productions) easily. Currently the staging and migration of iStore environments are done manually, and some installations have utilized their own change control systems and adopted their own naming conventions for JSP customization and iStore content to make the environment promotion process more managable.
With that said, there are concurrent programs that allow customers to perform site administration around migrating template mappings between instances (import and export). You can refer to the iStore Implementation & Admin. Guide under the iStore Template Mapping Import / Export Concurrent Programs.

Bob

Powershell Copy User Description from one Domain to another in one Forest

Hi.
I would like to copy the Description field from one domain to another domain in the same forest.
First I would like to get the following data from source domain
- SamAccountName
- Description
- Office
- Job Title
- Department
- Manager
I would like to get these informations to a txt-file. That I can manage myself, I think.
These values shoud then be set on the destination domain - and here my powershell skills are not suffecient. How do I add these values from txt-file to existing users? (if some users aren't there, the script should continue)....
I can Get-AdUser -Identity xxx -Server sourcedomain and Get-AdUser -Identity xxx -Server destinationdomain from the same powershell windows.
Regards
Carsten

Hi. Thank you very much for helping me out. I tried the above script and added in additional properties.
When I run the script, I only get one line in my csv-file, the Office-field is empty and all items appear on screen instead of output to file.
The script looks as follows:
$ou = [adsi] "LDAP:<Server>"
$searcher = New-Object System.DirectoryServices.DirectorySearcher $ou
$searcher.Filter = 'objectClass=user'
$result = $searcher.FindAll()
foreach($contacts in $result)
$contact = $contacts.GetDirectoryEntry()
$contact | Select-Object -Property @{Name="SamAccountName";Expression={$_.SamAccountName}},
           @{Name="Description";Expression={$_.Description}},
           @{Name="Office";Expression={$_.Office}},
           @{Name="Title";Expression={$_.Title}},
           @{Name="Department";Expression={$_.Department}},
           @{Name="Manager";Expression={$_.Manager}}
$contacts | Export-Csv -Path output.csv

Hardware Migration from one server to another server

Hi All,
We require more information pertaining to hardware migration from one server to another server without changing OS & DB.
We are preparing installation guideline document for the same.
Has anybody came across similar scenario?.
Any pointers on this will be highly appreciated.
Regards
Tushar Vhora

usually you don't have to care too much about the tools used (r3ldctl = R3load control | r3szchk = R3 size checker | r3load = R3 Load), because you normally use r3setup/sapinst to fulfill the copy/migration. r3setup/sapinst will call the appropriate tools with the needed options...
-> which release are we talking about?
-> which os and which database do you use?
-> how big is your source database?
-> do you have any time issues while making the copy?

Migrating from 2003 domain/forest level to 2008R2 with all DC's at 2008R2 and 2 other Domain External and Forest Trusts

Is there anything that needs to be done or considered when migrating from 2003 domain/forest level to 2008R2 with all DC's at 2008R2 with 2 other 2003 separate Domain incoming
and outgoing Trusts, one Trust that is a Forest Trust and the other is an External Trust? Is there any chance or risks that doing this upgrade will break either one of these Trust relationships? Some of the user accounts with SID history have been migrated
from both Domain Trusts to our domain. Any chance that this upgrade will break these relationships for users that are using SID history for access to folders and files in their old Domains? If so what can be done to protect these trusts and SID history, prior
to moving the Domain to 2008R2

Hi,
Based on my knowledge,
the Upgrade of the function level do not affect the trust relationship.
Besides, before you upgrade the Functional Level,
verify that all DCs in the domain are, at a minimum, at the OS version to which you will raise the functional level.
Once the Functional Level has been upgraded, new DCs on running on downlevel versions of Windows Server cannot be added to the domain or forest.
For more information about function level, we can refer to following links:

Domain Migration :from single domain to multiple domain.

Hi ,
We have an urgent requirement for the domain migration
The scenario is currently we are using MS AD as LDAP server to store portal users and thier credentials.
Lets say we have current domain name as : ad.abc.com
we are planning to migrate from this domain to number of domains.our requirement is to move the portal users into thier specific domain in batches.eg out of 5 users 2 has been moved to new domain and other 3 are still in ad.abc.com.
But after domain migration ,all the 5 users <b>should</b> be able to access all the applications and functionality of portals.
What should we do to achieve the same?
How portal applications will be affected by this?Can all the users access all applications without fail?
What exactly the LDAP does in portals?
Any help will be greatly appreciated
Thanks in Advance

Hi,
Yes, you need to prepare Active Directory and domains.
What's more, you need to upgrade existing Exchange 2007 servers to Exchange 2007 Service Pack 2 at least.

how do i migrate from one computer to another ?

Hi, what are the 2 OS versions involved?
It's generally best to do it on 1st boot of the new one, but we need more info about OSes & exact model Macs.

I just migrated from one Mac to another and I got a msg to contact Adobe tech support and report error code 150:30. What do I do?

Reinstall the software properly. Migration is useless due to the specifics of the activation system.
