I have a project to install version 7 Unity UM and migrate existing Unity version 5 users to this new server. My plan is to install the new server into the same domain using new server name. Since it's an upgraded version I cannot use DiRT, so shall I use COBRAS? If so, is it required to take the "old" server off of the network before the import into the new server?
Afterwards, I'll be adding a Unity HA server but I imagine that's not difficult or relevant to migrating the users to the new version/server which will be the initial activity.
The recommended method to migrate subscribers from one Cisco Unity server to another Cisco Unity server that reside in the same Active Directory would be:
1.Add the new Cisco Unity 7.0(2) server to the environment.
2. Back up the old Cisco Unity 5.0(1) server with the latest version of the COBRAS backup utility for Cisco Unity. The latest version can be obtained from www.ciscounitytools.com
3. Move subscribers from the Cisco Unity 5.0(1) server to the Cisco Unity 7.0(2) server with the latest version of the Global Subscriber Manager (GSM) utility from www.ciscounitytools.com (You can move one or more subscribers at a time).
4. Restore the desired data from the COBRAS backup with the COBRAS restore utility for Cisco Unity to the Cisco Unity 7.0(2) server. (You have the option to restore selected subscribers data).The latest version of the COBRAS restore utility for Cisco Unity can be obtained from www.ciscounitytools.com
