Cross Forest Migration from 2003 to 2007

[RobD]

Hello,

 

I'm having a few issues with power shell and migrating a bulk of users from a forest in 2003 to a forest 2007.

 

The two forests exist and there is a full trust between them, DNS has been set up so everyone can see everyone else.

 

The way I'm doing this is to migrate a user first using the migrate tool then the mailbox using this command:

 

$s=get-credential # (use your AD Account)

$t=get-credential # (use your CIG Account)

 

$s=Move-mailbox -TargetDatabase "MYMAIL07SERVER\First Storage Group\Mailbox Database" -BadItemLimit:"214" -identity "[email protected]" -GlobalCatalog NEWDC.DOMAIN.local -SourceForestGlobalCatalog OLDDC.DOMAIN.local -NTAccountOU "OU=BLAH,OU=BLAH,DC=NEWDOMAIN,DC=local" -MaxThreads 8 -SourceForestCredential $s -TargetForestCredential $t

 

 

Works perfectly but I want to use a csv (or text) to migrate users in bulk, so I migrated the user and entered the details into the csv file:

 

Username,

TL,

 

 

And used this script:

 

 

Import-CSV c:\scripts\users.csv | Get-Mailbox -Identity {$_.Username} | Move-Mailbox -TargetDatabase

 

"MYMAIL07SERVER\First Storage Group\Mailbox Database" -GlobalCatalog NEWDC.DOMAIN.local -SourceForestGlobalCatalog

 

OLDDC.DOMAIN.local -IgnorePolicyMatch -NTAccountOU "OU=BLAH,OU=BLAH,DC=NEWDOMAIN,DC=local" -BadItemLimit 214 -MaxThreads 10 -SourceForestCredential $SourceCredential -

 

TargetForestCredential $TargetCredential

 

 

But I keep getting the same error and have no idea what i'm doing wrong:

 

 

Get-Mailbox : The operation could not be performed because object 'TL' could no

t be found on domain controller 'NEWDC.DOMAIN.local '.

At C:\Scripts\MultipleMBmRD.ps1:1 char:46

+ Import-CSV c:\scripts\users.csv | Get-Mailbox <<<< -Identity {$_.Username} |

Move-Mailbox -TargetDatabase "MYMAIL07SERVER\First Storage Group\Mailbox Database"

-GlobalCatalog cigbridc02.cig.local -SourceForestGlobalCatalog bridc01.ad.broad

system -IgnorePolicyMatch -NTAccountOU "OU=Blah,OU=BLAH,DC=NEWDOMAIN,DC=local" -BadItemLimit 214 -MaxThreads 10 -SourceForestC

redential $SourceCredential -TargetForestCredential $TargetCredential

 

 

 

Any help would be really appreciated, thanks.
