Importing 700 Unity Subscribers from another Unity

For several reasons the customer would like to re-build a new Unity Server and bring the existing one eventually out of commission in order to be replaced by the new one.<br><br>There are currently 700 Subscribers currently defined on this existing Unity 2.46.135 system. They are in Voice Male only mode.<br><br>What are the suggested and supported procedures that we need to invoke to make this transition as painless as possible:<br><br>Items that are on my mind:<br><br>1) Copying the greetings of all Call Handlers and of Subscribers in order to paste them into the new Unity Server<br>2) How to export the existing Unity Subscribers from one system AND import them over to the new Unity Server<br>3) Can we also transfer the exiting voice mail messages that that Subscribers saved on the existing Unity Server to the new one.<br>4) For proper roll-over, can we have both Unity Servers up and running in parallel pointing to the same Call Manager with a range of different "uOne Ports" naturally. In this simulataneous Unity setup, must we have both the existing and the new Unity server in the same Exchange Site or not required.<br><br><br>


Re: Importing 700 Unity Subscribers from another Unity

This sounds like a job for the Full Database import/export tool. You can pick it up here:

You will need to use a program such as ExMerge from Microsoft to move the subscriber messages since the Full Database import/export will not. Check out this URL:;EN-US;Q174197

Check out this thread on having multiple Unity servers with one CM:

Also, you'll find a document Will wrote for migrating servers using ExMerge and Export/Import on the General Tools page on Worth a read...
