They contain critical information you will need to successfully upgrade and use Domain Time II v5.2.

IMPORTANT: If you are upgrading from version 4.x, be sure to read the 4.x to 5.x Considerations page

• Upgrading from earlier Domain Time II versions
  

  In general, all Domain Time II versions are completely interoperable (with minor exceptions), so you can upgrade any machine at any time without disturbing the program's operation.

  For best results, however, you should upgrade in this order:

  1. Any Server/Manager/Audit Server machines
  2. Master Server (the DC holding the PDC-emulator role)
  3. Slave Servers (deprecated; please consider changing the role to Independent)
  4. Independent Domain Time Servers
  5. Clients

  We recommend using the Domain Time II Manager to easily upgrade all your existing machines. Manager can investigate your network, automatically upgrade all your existing Domain Time machines, and provide a list of other machines that need to be upgraded manually. See the How to Manage Domain Time Remotely page for instructions on performing remote upgrades.

  Upgrades are available using the following methods

  • Download the latest Upgrade Patch File from our website.
  • Contact us to obtain the new distribution files on physical media.

• Upgrading from other time sync software
  You should not install two time sync programs on the same machine. The results of running two time services simultaneously are unpredictable, and usually not pretty. With the exception of Microsoft's Windows Time Service on Win2k or later (which Domain Time II handles automatically during installation), you must remove any other time management program before installing Domain Time. See the removal instructions provided by the manufacturer.
  Microsoft's Windows Time service
  Domain Time is much more accurate, reliable and easier to maintain than Windows Time, and also provides many additional important benefits without sacrificing any functions that Windows Time provides.

  If you do a fresh install Domain Time Server v5.1 or later on a machine running Windows Time, Domain Time will automatically disable the Windows Time service (since Server provides all necessary time services). A fresh install of Domain Time Client will also disable Windows Time, except on Domain Controllers and Cluster Servers, where Windows Time should be set to run in NoSync mode for compatibility reasons.

  If you are upgrading a machine running Domain Time, any existing Windows Time settings will not be changed. You should manually disable Windows Time on any Domain Time Servers after upgrade.
