Are you migrating to Unity or Unity Connection?

OK. Well, on the migration from Unity to Unity Connection. The first pre-requisite is that you have Unity 4.0(5) in order to use the COBRAS migration tool. If you don't have 4.0(5) and you need to migrate data, you'll need to upgrade to 4.0(5) before you can do that. Otherwise, you'll be doing a fresh install. Now assuming you can use COBRAS, you'll need to load COBRAS Export for Unity on the Unity server and choose the objects to be migrated. COBRAS is selective so you can select/deselect objects as needed. However, there are some things that COBRAS doesn't migrate so you have to rebuild those objects manually (or in bulk, where supported) on the Unity Connection server. Everything you need to know about COBRAS is here: http://www.ciscounitytools.com/Applications/General/COBRAS/COBRAS.html Read the help file top to bottom, then read it again. The next step is to install the COBRAS Import for Unity Conection tool on a laptop or server on your local LAN (technically, this could be Unity if it had to be). This requires some drivers to be installed first, then the import tool. The Help file will walk you thru all of the import steps as well. Before you get to this point, you need to get your Unity Connection server up and running and, if it's a cluster, make sure replication and server roles are configured properly.

CCM is fairly straightforward. You need to run the DMA (Data Migration Assistant) on your CCM server. If you have any errors or issues, you need to resolve them and re-run DMA before you proceed. DMA install requires that you reboot the Publisher server in the cluster as well. Then you need to copy that DMA file to an SFTP server so that CUCM can access the import file on the initial build. When you build the CUCM server, the installation process asks if you would like to import data from a Windows server and when you select yes - it will ask you for an SFTP or FTP location, credentials, etc to access the file. This is well documented in the links that Java sent to you. From there, you build the cluster as per installation docs.

Hope this helps you further understand the process. If you have other questions, just ask.
