Cisco unity4.x migration to CUC 8.X

Use COBRAS Briefcase mode.

http://www.ciscounitytools.com/Applications/General/COBRAS/Help/COBRAS.htm

You'll need to decide whether to integrate CXN with only the India CUCM cluster and rely on the Inter-Cluster Trunk to carry voicemail calls and MWI requests; or, to perform two separate integrations. The former has the advantage of allowing CUCM to enforce CAC while the potential disadvantage of additional configuration to ensure CUCM routes calls and MWI requests to the other cluster when appropriate.

Cisco unity4.x migration to CUC 8.X

Hi Vigeesh,

I agree with Mr. Jonathan .After reading the DOCS, BriefCase mode is the most preferred mode for migrating unity 4.2 to Connection  8.x

In hot mode, unity version 7.x is min. version or later .

In Briefcase mode, u can simply take backup from source server and restore it onto target server.
