Cross-Forest Move-Request Exchange 2007 to Exchange 2013

Hi people!!

We have two Exchange environments in different forest. We want to do a crossforest migration from Exchange Server 2007 to Exchange Server 2013 (Exchange Resource Forest with Linked Mailboxes). These are the configurations:

Domain: SourceDomain.local

ActiveDirectory: 2012 R2 Domain Controllers. Domain functional level 2008

Exchange: Exchange Server 2007 Service Pack 3 RU15

• 2 Mailboxes Servers à Cluster Continuous Replication
• 2 ClientAccess & HubTransport Servers with NLB by Microsoft
• 2 Edge Servers

Domain: TargetDomain.local

ActiveDirectory: 2012 R2 Domain Controllers. Domain functional level 2012 R2

Exchange: Exchange Server 2013 Cumulative Update 7 (CU7) (Exchange Resource Forest)

• 2 Mailboxes Servers à 1 DAG
• 2 ClientAccess Servers
• 2 Edge Servers

Both Exchange works fine. Exchange Server 2007 (SourceDomain.local) is currently in production and Exchange Server 2013 in Resource Forest (TargetDomain.local) is for migrating mailboxes in Linked Mailbox from Exchange 2007. We´ve configured a Linked Mailbox and it works.

We´ve configured a trust between the forests:

• Conditional Forwarders in both domains
• Forest trust, One-way outgoing, Forest-wide authentication: TargetDomain.local, Domains trusted by this domain (outgoing trusts)à SourceDomain.local – Forest- Transitive SourceDomain.local, Domains that trust this domain (incoming trusts) à TargetDomain.local – Forest – Transitive

We´ve configured following prerequisites for migrating:

• Accepted Domains à Both Exchanges have an accepted domain:Company.com as Internal Relay Domain
• Send Connectors à Both Exchange have a send connector (CrossForest) with Address Space:*.company.com and Smart Hosts
• Test Mailflow. (Currently, MXs for company.com are in Exchange 2007)
  • Mail from external source to mailbox in Exchange 2007 à OK
  • Mail from external source to mailbox in Exchange 2013 à OK
  • Mail from external source to Linked Mailbox in Exchange 2013 an account in DomainSourceDomain.localà OK
  • Internal Mail from Exchange 2007 to Exchange 2013 à OK
  • Internal Mail from Exchange 2013 to Exchange 2007 à OK
• MRSPROXY. We´ve activated MRSProxy in both Client Access Servers in Exchange 2013

For Migrating Mailboxes, from Client Access Server in Exchange 2013 in PowerShell, We’ve done these steps:

• Preparation Mailboxes. Previously We´ve stored credentials with Get-Credential. $SourceCredentials à SourceDomain.local and &TargetCredentialsà TargetDomain.local We´ve run this command: Prepare-MoveRequest.ps1 –identity “Testuser”–RemoteForestDomainController DC1.SourceDomain.local –RemoteForestCredential $SourceCredentials –LocalForestDomainController DC1.TargetDomain.local –LocalForestCredential $TargetCredentials –LinkedMailUser –TargetMailUserOU “OU=Mailboxes,DC=TargetDomain,DC=local” –Verbose It finished fine and 1 mailbox ready to move. We´ve checked It´s created a Disable User in TargetDomain.Local.
• New-MoveRequest. Previously We´ve stored credentials with Get-Credential. $SourceCredentials à SourceDomain.local We´ve run this command: New-MoveRequest –identity “Testuser” –RemoteLegacy –TargetDatabase “DB1” –RemoteGlobalCatalog “DC1.SourceDomain.local” –RemoteCredential $SourceCredentials –TargetDeliveryDomain “company.com” It finished with this error: MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80004005, ec=2423)

After this error, We´ve done following changes and tests:

• To check network permission between both Exchanges and Active Directory. Currently we have any/any permissions.
• To resolve NETBIOS name and FQDN names beween both Exchange. In TargetDomain.local We added in host file NETBIOS name and FQDN name of all Exchange Servers 2007. In SourceDomain.local we can do ping to NETBIOS and FQDN without to edit host file.
• Import Root CA Between both Exchange Organizations. In each Exchange server in SourceDomain.local import Root CA we use in Exchange 2013 and in each Exchange server in TargetDomain.local import Root CA we use in Exchange 2007. After this, We´ve checked to access OWA without warning certificate (Internal Access OWA).
• Restart all Exchange Servers 2013.

After these steps we carry on with the same error:

MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80004005, ec=2423)

I´ve tried as well to do the movement of Mailbox from EAC in Exchange Server 2013. After insert Source Credentials, we have this warning:
