  • Merging into one forest

    I work for a company that has been taken over by another company. We have two seperate domains but it has been decided that inorder to share global address lists and calenders etc we should be merging into one forest.

    Having never done this i have afew questions

    How would i go about this, what would the implications be ?

    Thanks in advance

    There need to verity the correct access requirements from each company and to the other company. There also need to know the routhing + VPN etc., security issues etc. before give a real solution to this topic.

      Hi,

      The connectivity would be through SDSL VPN managed by a firewall. We run the same virus scanning software and now operate the same IT policies.

      What else can i tell you ?

        Yuval's answer was perhaps a bit theoretical.

        Technically, you need to:

        1. migrate users and groups from one forest to the other. Investigate ADMT, for instance
        2. migrate mailboxes to the other exchange org, using exmerge or the Exchange Migration Wizard
        3. Migrate computers, etc.

        There is a lot of info on this subject with MSFT.

          The end result is that we want to share global address books and calenders and we would like retain and maintain our own servers and exchange boxes. IS there another solution that you know off ?

            That's another question altogether. In your first post you stated that you wanted to merge the forests! Exchange coexistence is simpler (well, different).

            You have some options.

            1. manual import/export
            2. use the Active Directory Connector of Exchange
            3. use MIIS feature pack
            4. ...

            there's probably a lot more. If you also need free/busy data, look at Exchsync.exe

              MErging inot one forest was the solution ic oudl see working, but the end result is the desire to share calender and global address lists.

              Of the options you have listed which do you think is the better ? Do you know where i can go to research this further, particularly the AD connector of exchange

                There lots of implementations scansions like:


                1. http://www.msexchange.org/tutorials/...tion-Tool.html

                * Please note that there no real offical support for this tool as I know.

                2. Migrate to one forest and one Exchange org.

                3. Use some tool for identity managment, like Microsoft identity server.

                  I currently have a client in the exact situation you are in. The first thing the client wanted was to share the GALs and Free/Busy (migration will be performed much later).

                  I am using two-way ADC connection agreement (I have Exchange 5.5 on one side, so IIPF is not an option) to create contact objects in the adjacent forest (make sure NOT to replicate contact objects as it will cause loop) and InterOrg Replication Tool to sync the Free/Busy information.
                  Quite a pain to setup, but works like a charm.

                    Yuval, we have already talked about it. This is a rumor and I have no idea where it came from. After going over the whole InterOrg Replication Utility documentation, I have not found a single word about it not being supported. Moreover, I would expect the fact of it not being supported to be found at the following KB: http://support.microsoft.com/default...b;en-us;238573. Yet, not a single word about it not being supported and there are more KBs about troubleshooting the tools and the fact that it does not support some specific things like replication between servers with different languages: http://support.microsoft.com/default...b;en-us;238573
