Migrating from Cisco Unity Express to Cisco Unity Connection

[Volodymyr Yavorivskyy]

Hello,

We are going to migrate from Cisco Unity Express 8.6.6 to Cisco Unity Connection 9.1.2. Therefore, we need to migrate all mailboxes without data lost.

So, the questions are next: is it possible? Which tools we should use and what  steps we need to pass?

Thanks,

Dont think its possible. The closest you might be able to get is import into Unity Connection 8.x and then upgrade to 9. The tool is listed here but keep in mind its not TAC supported:

Based on my experience of keeping the data (i.e. voicemails for users) it is really not worth it.

Because all these voicemails will add up the Mailbox Space and user will get unnecessary "mailbox full" warnings even though they may be deleted (it takes around 2 weeks to get rid of the deleted voicemails)

Hence, my recommendation would be to do a stare and compare for the most part and build all the Call Handlers etc, this will give you even better chance to get rid of all the unwanted stuff.
