Cross Forest Migration from 2003 to 2010 RRS feed

  • Question

  • Hi Guys, Sorry to ask what is probably an age old question but I am looking for some tips on a migration. I have two forests, two separate namespaces that I wish to bring together. I have seen articles about moving the mailboxes but I do not plan for this to be a fast process so I would like some kind of sync in process for a while just like using a Notes connector for instance.

    Both Forests running Windows 2003 Forest one is Exchange 2003 one is Exchange 2010. Initially I will create a two way trust then I am looking to share GALs and free busy/availability between the Exchange organisations. Ultimately I will bring them into one forest using ADMT and use a cross-org mailbox move i.e. from the Exch2003 to the 2010. Its the same as an aquisition but in this case its always been one company but we are now looking to collapse the political bounderies which lead to two forests in teh first place. 

    Sound ok so far??

    I am working out the best way to do the initial phase and was looking at identity integration FP Sp2; say it’s supported on Exchange 2003 Enterprise only. Has anyone else worked on a similar project? I would love to hear your experiences and advise.

     

    Thanks in advance.

  • Hi Jonas, Thanks for this. Is third party tool is the best option? 2010 offers Federated sharing which would do what I want if both servers were Exchaneg 2010 right? but as one is 2003 this is not an option. Are there any native ways to do this between 2003 and 2010 ?

    http://www.testlabs.se/blog/2010/05/24/cross-forest-migration-in-lab/ is good if you have  few user or just doing POC

    if you have a lot of user you have to make sure users on each forest are visible in other forest gals for that


    here is a good refrence for galsynch

    Like Dhruv wrote, it depends on how many users, data etc..

     

    There are 3rd part tools, you can checkout this tool, it will give you F/B and Galsync

  • Along this topic....

    Is a Cross Forest Move possible where the Two Domains (Companies) refuse to allow a Trust relationship between the Active Directory Domains.  In this project we are encountering such Political constraints, which dramatically hamper the New-MoveRequest functionality.  Is there a way to circumvent the Domain Level Trust requirement? 

    Additionally, the challenges just continue to mount, the Trust challenge is complicated by the fact that one of the Client's Domain and Organizations are Virtual, and built their environment around a Local Namespace (Agency.State.Local) Domain FDQN.  They never intended to be visible or route to the rest of the environment.  In fact, Source and Target also do not participate in a Common DNS, and do not forward or update their DNS with others, they truly are totally separate from that respect.  IP Routing and addressing, both use 10.x.x.x addresses which are presented as Public Addresses  (NAT) through their respective Firewalls.

    Any ideas?
