Transferring DHCP role to the new domain controller

The DHCP database and settings can be backed up to allow the replacement server to quickly take over the DHCP server role and service clients again. If DHCP is not running on the SBS server, you may skip this step. To back up the database, follow this steps:

1. Open DHCP Management MMC by selecting Start, then All Programs, Administrative Tools, DHCP.
2. In the console tree, select the SBS server.
3. On the Action menu, click Backup.
4. In the Browse For Folder dialog box select the folder where you want to store the backup DHCP database and then click OK.

To allow the new server to act as a DHCP server, you must install the DHCP Server role and then configure the server’s settings. This steps assume that you have backed up your SBS Server settings and will restore them to the new server. If you are hosting DHCP on another server, you may skip this step.

Install the DHCP Server Role

You can use this procedure to install and configure the DHCP Server role, using the Add Roles Wizard. Membership in Domain Admins or equivalent is the minimum required to perform this procedure.
 

To install DHCP

1. Do one of the following:
   1. In Initial Configuration Tasks, in Customize This Server, click Add roles. The Add Roles Wizard opens.
   2. Click Start and then click Server Manager. In the left pane of Server Manager click Roles and in the details pane, in Roles Summary, click Add Roles. The Add Roles Wizard opens.
2. In Before You Begin page click Next.
3. In Select Server Roles, in Roles, select DHCP Server and then click Next.
4. In DHCP Server click Next.
5. In Select Network Connection Bindings, in Network Connections, select the IP addresses that are connected to the subnets for which you want to provide DHCP service and then click Next.
6. In Specify IPv4 DNS Server Settings, in Parent Domain, verify that the name of the DNS domain that clients use for name resolution is correct. For example, if your domain is named example.com, verify that the DNS domain name is example.com.
7. In Preferred DNS server IPv4 address, type the IPv4 address of your preferred DNS server, and then click Validate. In Alternate DNS server IPv4 address, type the IPv4 address of your alternate DNS server (if any) and then click Validate.
8. Click Next. In Specify IPv4 WINS Server Settings select one of the following:
   1.  If you do not have WINS servers on your network, select WINS is not required for applications on this network.
   2. If one or more WINS servers are deployed on your network, select WINS is required for applications on this network. In Preferred WINS server IP address, type the IPv4 address of your preferred WINS server. In Alternate WINS server IP Address, type the IPv4 address of your alternate WINS server (if any) and then click Next.
9. In Add or Edit DHCP Scopes click Add. The Add Scope dialog box opens.
10. In the Add Scope dialog box type values for all required items and in Subnet Type select either Wired or Wireless, depending on the IP address lease duration that you prefer and then do one of the following:
    1. To automatically activate the scope immediately after DHCP installation is complete, click Activate this scope. If there are computers or devices on the network that have static IP addresses, do not activate the scope until you have created an exclusion range. The exclusion range prevents the DHCP server from leasing IP addresses that are already in use by a statically configured device.
    2. To manually activate the scope later, use the DHCP Microsoft Management Console (MMC).
11. Click OK. This returns you to the Add or Edit DHCP Scopes page. If your network has multiple subnets that are serviced by this DHCP server, add scopes for each subnet using steps 9 and 10. Click Next.
12. In Configure DHCPv6 Stateless Mode, select whether you want to configure the DHCP server for DHCPv6 stateless operation and then click Next.
13. In Authorize DHCP Server, do one of the following:

Install the Exchange Server

Using a copy of 64-bit Windows Server 2008R2 Standard Edition, install a new server. The server should be joined to the domain manually as a member server. Once the server is installed, apply all the Windows Service Packs and updates.

There is no requirement that the Messaging Server should be a domain controller. If you have additional DCs, it is not recommended making this server a DC. 

 
Install Exchange and Migrate Data
To install the Windows Server 2008R2 operating system prerequisites, for a computer that will host the Hub Transport, Client Access, and Mailbox server roles, use the Powershell interface:

1. In Start menu run PowerShell as Administrator.
2. In PowerShell windows type Import-Module ServerManager.
3. Wait for the command to be completed and then type Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,Web-Asp-Net,Web-Client-Auth,Web-Dir-Browsing,Web-Http-Errors,Web-Http-Logging,Web-Http-Redirect,Web-Http-Tracing,Web-ISAPI-Filter,Web-Request-Monitor,Web-Static-Content,Web-WMI,RPC-Over-HTTP-Proxy -Restart. This command will install all prerequisites needed by a typical installation of Exchange. After the command will be complete, the server will restart.

Install Exchange Server 2010

1. Download and install Microsoft Office 2010 Filter Packs from http://go.microsoft.com/fwlink/?LinkId=191548 .
2. Install Exchange Server 2010 from a media or a downloaded copy by lunching setup.exe in the root folder on the Exchange DVD or extracted folder.
3. In Introduction window click Next.
4. In License Agreement window check I Accept the terms in the License agreement and click Next.
5. In Error reporting window click Next.
6. In Installation type window select Typical Exchange Server Installation, check Automatically install Windows Server roles and features required for Exchange and click Next.
7. In Configure Client Access server external domain check The Client Access server role will be Internet facing.
8. In Enter the domain name you will use with your external Client Access servers type the name of your MX record (for example: mail.contoso.com).
9. Click Next.
10. In Customer Experience Improvement Program click Next.
11. In Readiness Check that all requisites are installed (all checkmark must be green) and click Install.
12. Review that all tasks has completed successfully and click Finish.

In this time, you must change the firewall and the DNS setting. Now the new exchange is ready to receive and send mails. This will be possible after you change the forwarding roles on your firewall. You must change forwarding roles for ports 25, 80 and 443 to messaging server IP.

Some changes in DNS are also needed. To do this follow the procedure:

1. Open Start menu, Administrative tools and lunch DNS.
2. In the left pane expand SERVER_NAME, Forward lookup zones (Where SERVER_NAME is the name of the DNS Server).
3. Expand EXERNAL_DOMAIN_NAME and select A Record for the name of remote access – by default is remote and right-click properties (INTERNAL_DOMAIN_NAME is the name of RWW).
4. Change the IP address with the address of the new messaging server.

Creating data and migrating users to the new Exchange server
First step to do is creating a new Offline Address Book:

1. Open Start menu and open Microsoft Exchange Management Shell as Administrator.
2. Type the command New-Offlineaddressbook -name “OAB_NAME”default global address list” -server “SERVER_NAME” (where OAB_NAME is the name of Offline Address Book and SERVER_NAME is the name of Messaging server).
3. After the new OAB is created, it must be updated with the command Update-OfflineAddressbook -Identity “OAB_NAME”.
4. At this point we must set this OAB as default OAB for Mailbox Database on Messaging server with the command Get-MailboxDatabase | Set-MailboxDatabase –offlineaddressbook “OAB_NAME”.
   

 

After the database is ready, you can begin moving Mailbox Location with pipeline Get-Mailbox -Server SBS_SERVER | New-MoveRequest -TargetDatabase “NEW_DATABASE” (where SBS_SERVER is the name of the SBS Server and NEW_DATABASE is the name of the Mailbox database on Messaging server). During the move operation, user will be able to send and receive mails, but when the operation is completed, he will be prompted to restart Outlook.

At the end they remain only public folders. You can move them simply with a script from the new Exchange server:

1. Open the Exchange Management Shell as Administrator.
2. Navigate to the folder <Drive>Program FilesMicrosoftExchange ServerV14Scripts (where <Drive> is the system drive).
3. Run a PowerShell script .MoveAllReplicas.ps1 -Server “SBS Server” –NewServer “New Server” (where “SBS Server” is the name of the SBS Server and “New Server” is the name of the new Exchange server).
4. Wait few days, that all fodders will be moved completely.
