OCS2007R2 to Lync Server 2010 migration RRS feed

  • Question

  • Hi,

    Have an OCS2007R2 pilot with about 80 users using it. I have now informed the customer about Lync and they want to make the move to Lync before they roll out Communicator for the rest of the users, about 3,500 users.

    They only use the IM and status, they don't use A/V Conferencing, Telephony and so forth. Just a standard installation with no policies, dial-plans and stuff.

    The easiest way is to make an migration right?

    Question: If we just want to migrate the users using Move-CsLegacyUser and not merge topologies and migrate policies and settings, nor the users buddylist; must we install WMI Backward Compatibility Package and go for the "full migration steps"?

    Is it possible to just install the Lync Server 2010 environment aside of the OCS2007R2 environment and just move legacyusers to the new environment. Or will the Lync Server not recognize the old OCS WMI and not find and be able to move the users before we install the package?

    Or must we install the package and merge the topology for the move to work but we can skip the migration of policies and settings?

    The current users (80 ppl) where about 30 from the start and it grew when people heard about it so we can just move the users without any further notice and it is legit to move them without any buddylist. But it's not the prefered way. We are now investigating the ways to do this.

  • Dear Friend ,

     

    If you migrate in properway - http://technet.microsoft.com/en-us/library/gg413057.aspx   you will not loose anything. But if it crash ? you can go for a second way(Deploy the Lync and add existing user to lync). But little bit harder but can be done.

     

    Enjoy!!!

  • if you properly deactivate / uninstall OCS 2007 R2 from your organization ( not force remove ) all the necessary related information will be removed from Active Directory and you can then install Lync on the same machine

    You can use the same server name as long as you disjoin the OCS server from the domain , delete the computer account from Active Directory if it wasn't deleted automatically.

  • Hi the most appropriate way it to you install the package and merge the toplogy for the move and migrate all the settings that you want to migrate.

    this way it will be easier for the migrated users and also for you from losing everything.

  • Ok, so moving users without the mergeprocess can be done.

    Last question, In a recent meeting they asked if they could use the same hardware in the lab environent. they have a physical server there with about 15 test accouns enabled for ocs.

    If they want to use the same hardware, can we just disable the ocs users -> uninstall ocs2007r2 -> reinstall the os and then do a new fresh lync server 2010 installation? will all information regarding ocs200yr2 dissapear from AD or must we use ADSI edit to remove some parts?

    They also want to use the same name on the server, and for the lync server 2010 standard edition it needs to bne the exact fqdn of the server right? so all information must be removed...
