Yes, you can use powershell to export all of the old mailboxes to pst

If you have the space and enough room, you can do this for everyone at once

$users = Get-ADUser -filter* | Select SamAccountName
foreach ($user in $users)
{
Export-Mailbox –Identity $User -PSTFolderPath "C:\PST's\$User Mailbox.pst"
}

Open in new window

or if you want to use a .txt list.

$users = Get-Contents "C:\users.txt"
foreach ($user in $users)
{
Export-Mailbox –Identity $User -PSTFolderPath "C:\PST's\$User Mailbox.pst"
}

Open in new window

or by group

$users = Get-ADGroupMember -identity "Group Name" | Select SamAccountName
foreach ($user in $users)
{
Export-Mailbox –Identity $User -PSTFolderPath "C:\PST's\$User Mailbox.pst"
}

Open in new window

ASKER

so the idea is to export pst and then import pst to specify users?

Have the users been created in the new forest/domain already? Any forest trust between the two companies? You could also look at a Cross Forest Migration as well.
