Unified Messaging Migration Path Strategies

Two strategies to use to enable a unifiedmessaging migration path:• Strategy 1

– Install Cisco Unity into its own forest or domain

• Strategy 2

– Integrate Cisco Unity into an existing forest or domain

Considerations When Choosing a Migration Strategy

Strategy 1All new hardware

Create a new forest with all the steps for a separate infrastructure.

Do not modify the schema until the actual migration time.

Create storage capacity.

Create system security or Firewalls.

Create a backup schedule and implement backup hardware.

Strategy 2All current Infrastructure must be checked for readiness or made ready for Cisco Unity.

Modify the schema.

Check storage capacity.

Create system security or Firewalls.

Include Cisco Unity servers in the backup schedule to existing backup hardware.

Migration Strategy 1

Strategy 1: Premigration

Separate Exchange servers and DC/GC can be used.

Example: Strategy 1—Migration

Strategy 1: Migration• New Cisco Unity server must be the same version as the old Cisco

Unity server.

• Old Cisco Unity server is still serving as voice-mail server.

• Run DBWalker utility on old server before backup.

• Back up data using Cisco Unity DiRT or Veritas Backup Executive.

• Restore data using Cisco Unity DiRT restore process.

• Remove old Cisco Unity server.

Example: Strategy 2—Premigration

Strategy 2: Premigration• Cisco Unity is installed into

existing forest or domain as a member server.

• Exchange can be installed on box, or external server can be used.

• Hide voice mailboxes so they are not visible in the global address book.

to move voice-mail subscriber attributes.

• Third-party utility can be used to move voice messages, or users can forward them via Cisco Unity Inbox.

What Are the Client Message Retrieval Options for Voice Mail and Unified Messaging?

What Are the Cisco Unity Assistant and Cisco Unity Administrator Access Issues in Strategy 2?

Issues• Unified Messaging deployments are not complicated

because there is only one account for e-mail and voice mail.

• Voice-mail deployments use multiple accounts. Each account has a unique SID.

• Use the GrantUnityAccess utility to link the accounts.

• Fred logs into domain with Fred account.• Cisco Unity subscriber account

is linked with VM-Fred account.• Fred account cannot be

authenticated by Cisco Unity.

What Are the Cisco Unity Assistant and Cisco Unity Administrator Access Solutions?

Solutions• Configure Internet Explorer to prompt for a username,

password, and domain.

• Run GrantUnityAccess utility to link the SID from domain accounts with the SID for voice-mail accounts.

• If the SIDs reside in different forests, a trust must be configured to allow the voice-messaging forest to trust the corporate forest before GrantUnityAccess will work.

Summary

• Deployment requirements include sizing and scaling, codecs, firewalls, third-party applications, and TAC access.

• Two strategies can be used to enable future unified messaging upgrades: Cisco Unity installed into its own forest or domain and Cisco Unity integrated into an existing forest or domain. Identify possible migration paths from a voice-mail-only Cisco Unity system to a unified messaging system.

• There are premigration path considerations for moving a voice-mail-only Cisco Unity system to a unified messaging system.

Summary (Cont.)

• Voice mail and unified messaging characteristics for client message retrieval vary.

• Client access is complicated when Cisco Unity is installed as a voice-mail-only solution. The main issue is with authentication.

• Solutions for Cisco Unity Assistant issues include setting up Internet Explorer to prompt for a username, password, and domain; running the GrantUnityAccess utility to link the SID from domain accounts with the SID for the voice-mail accounts and, if the SIDs reside in different forests, configuring a trust to allow the voice-messaging forest to trust the corporate forest before granting Cisco Unity access.
