Microsoft Active Directory Migration Tool 3.2

This microsoft tool simplifies the process of migrating objects and restructuring tasks in an Active Directory Domain Service (AD DS) environment. You can use ADMT v3.2 to migrate users, groups, service accounts, and computers between AD DS domains in different forests (inter-forest migration) or between AD DS domains in the same forest (intra-forest migration). ADMT can also perform security translation (to migrate local user profiles) when performing inter-forest migrations. This tool is available for download in the Microsoft Download Center.

Tool for Merging data from one Exchange server to another

Use the Microsoft Exchange Server Mailbox Merge Wizard program to extract data from mailboxes on a Microsoft Exchange Server and then merge this data into mailboxes on another Microsoft Exchange Server. The program copies data from the source server into Personal Folders (.PST files) and then merges the data, in the Personal Folders, into mailboxes on the destination server. The ability to merge data to and from an Exchange Server makes this program an invaluable tool with a variety of uses- especially during disaster recovery. The program can also replace existing data instead of merging new data if specified by the Administrator. Mailbox Merge has some limitations. Please read the tools documentation before using this program.

Different Roles of Exchange Server 2010

Mailbox Server Role

The CAS role handles all connection between all external clients that need email access. All the protocols necessary for client access are handled in the CAS, including POP3, Internet Message Access Protocol 4 (IMAP4), Messaging Application Programming Interface (MAPI) and HTTPS. The CAS also supports Microsoft Outlook, Outlook Anywhere, Outlook Web App (OWA) and Exchange ActiveSync (EAS).

Hub Transport Server Role
This role processes, routes and delivers all mails sent through Exchange 2010. The hub transport server oversees message filtering and formatting and checks the validity of attachments. The hub transport roles also records and journals email messages. The server role can work in conjunction with an edge transport server role.

Edge Transport Server Role

When installed this optional server role provides an added layer of security between the Exchange server 2010 organization and the outside network.The edge transport server checks that messages sent from outside an organization are free from spam and viruses before routing them to the hub transport server. Outgoing mail from the hub transport server is routed to the edge transport (if deployed) before leaving the Exchange organization.

Unified Messaging Server Role

The UM server, which is also optional, integrates an organization's PBX system with Exchange Server 2010. This stores business data like voicemail and faxes with email, calendars and contacts in users' mailboxes. Users also get features like call answering, automated greetings, message recording and fax support.
