How Swing Migration Works for exchange server Just for Egypt Engineers

 How Swing Migration Works


Swing Migration is a process to accomplish either a version upgrade or server replacement migration without giving up the domain, or the server name, or the Exchange Information Store in the process, all while working offline with an open time line.
You get a clean server installation retains all the critical Active Directory domain information and predictable results. It's the most transparent method for bringing all versions of SBS, NT4, Win2K, or Win2003-based domains as upgrades to SBS 2003. This methodology works for non-SBS projects as well. You can learn a process flexible enough for most any project in any production environment regardless of the hardware changes involved.
Swing Migration solves technical issues, business interruption, and scheduling challenges. Construction is performed almost entirely offline, with an open-ended timeline. No repairs are needed if a problem halts the upgrade. Swing migration minimizes the preparations and changes to the production server, and that server remains in operation during the upgrade. Only during the final transition do you move the data and Exchange Stores to the fully constructed new server, which you then slide into service to replace the previous server. The domain accounts remain unchanged, you can keep the server name, and alternate paths in the process use the previous hardware. These upgrades have predictable outcomes; they are safe even for entry level technicians.
What is shown below is a diagram of the process, and further below is a simple outline of the process.

  • [TempDC] Clean install a Windows 2003 Server (using SBS media) as a workgroup server only.
  • Manually join it to the existing SBS domain, preparing this server as a Temp DC.
  • Install DNS, perform DCpromo and designate as a Global Catalog Server.
  • Replicate DNS and AD then shutdown and disconnect
  • Seize all FSMO roles
  • Purge the Active Directory metabase and DNS of all previous Domain Controllers, Exchange and DNS Server references
  • [FinalDC] Clean install Windows 2003 Server just as before, reuse the original SBS Server name and IP. This server will look just like the previous SBS for name, IP, AD, and UNC/URL paths.
  • Install DNS, perform DCpromo, designate as Global Catalog Server.
  • Replicate DNS and AD.
  • Seize all FSMO roles, purge the Temp DC from DNS and AD
  • Finish normal SBS Setup using this Server
  • Complete the balance of migration of Exchange, all Data, and shared resources
  • If desired, perform a migration of the intact Exchange Information Store as a direct mount of the previous Information Store as if it were an offline restore. Reconnect mailboxes.
  • Perform a direct substitution of the new server for the old SBS
  • Deploy Applications as normal for SBS.

  الحل بسيط جدا عايز الكونتاكت تتحدث دايما بحيث انك لما تضيف يوزر جديد يسمع في الكونتاكت اول حاجه بتدخل علي in office 2003 tools --- email account ---- add address book --- internet directory service (LDAP) type your server name then login info . mark this server require me to logon type any user on active directory and its password then save and close outlook and open it again now you will find all your active directory users in address book

3 things has to be done for better performance

  Tips from Goutham: 3 things has to be done for better performance: By default, XP displays extra graphic objects for menu items which can slow down your display. 1. To turn off these selectively... Right click My Computer Select Properties Click Advanced tab Under Performance, click Settings button To turn them all off, select Adjust for best performance Preference is to leave them all off except for Show shadows under mouse pointer and Show window contents while dragging 2. To speed up the display of the Start Menu Items, turn off the menu shadow. Right click open area of the Desktop Select Properties Click Appearance tab Click Effects button Uncheck Show shadows under menus 3. You can increase system performance by loading more of the system into memory. DO NOT attempt this with less then 512MBs of ram. Your system will become unstable. Click Start Click Run Enter regedit Click OK Go to HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management Double cli

The difference between DNS and NDS

  Novell Directory Services(NDS) - Novell Directory Services (NDS) is a popular software product for managing access to computer resources and keeping track of the users of a  network , such as a company's  intranet , from a single point of administration. Using NDS, a network administrator can set up and control a  database  of users and manage them using a  directory  with an easy-to-use graphical user interface ( GUI ). Users of computers at remote locations can be added, updated, and managed centrally. Applications can be distributed electronically and maintained centrally. NDS can be installed to run under  Windows NT , Sun Microsystem's Solaris, and IBM's  OS/390  as well as under Novell's own  NetWare  so that it can be used to control a multi-platform network. NDS is generally considered an industry  benchmark  against which other products, such as Microsoft's Active Directory, must compete. Lucent Technologies plans to integrate NDS into its own QIP product
