Can Active Directory user account SID be exported to file?

Points of My Scenario
1. I am admin of a Windows Server 2003 domain
2. I have a cross-forest trust with an external forest & domain
3. Users must be migrated to the external domain
4. I have been tasked to provide the SID history of my domain users (I'm not sure this is a proper request).
QUESTION: Can the SID history of accounts be exported to file?

Actually for Quest PS syntax it's better to use SID attribute, instead of objectSID.
So, proper syntax is

Get-QADUser -name * -sizelimit 0 | Select sAMAccountName,givenName,sn,SID | Export-CSV c:\SIDs.csv

You can use a tool called adfind

adfind -default -f "&(objectcategory=person)(objectclass=user)(sidhistory=*)" samaccountname sidhistory

That will only list users that have sidhistory populated.

I think what you want to do is use the Active Directory Migration Tool - ADMT - check it out.
Free tool for managing users' photos in Office 365

Easily upload multiple users’ photos to Office 365. Manage them with an intuitive GUI and use handy built-in cropping and resizing options. Link photos with users based on Azure AD attributes. Free tool!

That's strange. Why they want to have SIDs of all of your users? Maybe they want to somehow enumerate them in the new domain (I don't know). As leew mentioned, to migrate users from one domain into another you have to use ADMT which creates SID History for an object automatically.

SID is unique for each object, so when you migrate user into another domain, its SID is assigned from that domain SID's database and it's also unique within that domain. The only difference for existing user in the domain is that SID History is set up with SID from previous domain to preserve access to network resources without changing ACLs on files/folders by administrator.

Anyway, if you wish to export all user SIDs to text file, you can use Microsoft DS Tools for that, Quest PowerSHell module for AD or mentioned ADFIND by Mike.

To export SIDs using DS Tools, run this syntax on any DC or workstation with Administrative Tools installed

dsquery * -filter "&(&(objectClass=User)(objectCategory=Person))" -limit 0 -attr sAMAccountName givenName sn objectSID >>c:\SIDs.txt

for Quest PowerShell use

Get-QADUser -name * -sizelimit 0 | Select sAMAccountName,givenName,sn,objectSID | Export-CSV c:\SIDs.csv

or modify a little bit Mike's ADFIND example (if you wish to use ADFIND)
