User migration between Unity systems

Unanswered Question
Jul 7th, 2008


We are planning to upgrade from Unity 4.2(1) to Unity 5.0(1).

The upgrade strategy is going to build a separate Unity system, hook it up to Corporate Exchange and Call Manager cluster and then gradually migrate users.

Does anyone know of the tool that could perform the migration for selected subscribers from one Unity system to another?



I have this problem too.

Wow! This is exactly what I was looking for. Perfect!

The tool is fairly new and training videos available on

Are you aware of any caveats for backing up data off 4.2(1) and restoring onto 5.0(1)?

not that i know of, but some other great NetPros like Tommer are using it and seem to like it =) :

"The way I prefer to install Unity servers now, if it permits, is to use Cobras Tool."

"You can also use COBRAS which is not TAC support *yet* but works very well I have found."

once this tool gets TAC support no one will be able to live without it =)
