Determine Cluster Migration Strategy
Single Staged Migration with New Hardware

Key Points: A parallel CUCM 6.11 Cluster should be built using new hardware and pre-staged with configuration to support the existing production network. Migrate Users from existing system to the new system in one window (flash cut) or multiple windows (shrink and grow). Idea for small site with less than 300 IP Phones in one maintenance window and can scale to a very large site in multiple windows.

21

Determine Cluster Migration Strategy
Multi-Staged Migration with Existing Hardware (Hybrid)

Key Points: Individual components are migrated in stages. Separate maintenance window is used for each component upgrade or migration. The Multistage system migration on existing hardware is the recommended approach for medium to large network.

22

Determine Cluster Migration Strategy
Multi-Site Migration (Hybrid Network)
Key Points: Components are migrated from the base release set to the target set on a site by site basis during separate maintenance windows. A Hybrid network will exist across multiple sites. Within each site, either a singlestage or multistage migration strategy can be used for that particular site. A component that is common to multiple sites may affect the interoperability that will require those sites to be migrated concurrently.

Determine CUCM Software Migration Strategy
CUCM 6.1 Software Installation Options
CUCM 6.1 Software installer has three options:
Basic Install
• Installs a fresh copy of CUCM 6.1 onto the server. • This option is used for all Subsequent Nodes Installation.

Upgrade During Install (U1 install)
• Installs a fresh copy of CUCM 6.1 and a Engineering Special during the same installation process. • This option is used for future CUCM installation where cluster already has Engineering Special installed on top of the base image.

Windows Upgrade (W1 install)
• Installs a fresh copy of CUCM 6.1 and import DMA backup file from CallManager 4.x data • This option is used for First Node (Publisher) Migration.

Determine CUCM Software Migration Strategy
CUCM 6.1 Software Upgrade/Fallback Options
L2 Upgrade
• Linux to Linux Software Release Upgrade • This option is used to install Software Upgrade or Engineering Special Patch onto the Inactive Partition of the same server. • Local DVD and SFTP/FTP Server are supported for L2 Upgrade. • CUCM 5.x to 6.1 Upgrade is a L2 Upgrade

L2 Fallback
• Linux to Linux Software Release Fallback • This option is to fallback Software version to the software release on the Inactive Partition. • You can use Recovery CD, CLI Command, or OS Administration interface to switch between software releases on two Partitions.

31

Determine CUCM Software Migration Strategy
RAID and BIOS Firmware Leveling
• CUCM 6.1 Installation DVD automatically flash RAID firmware and BIOS firmware to match versions with CUCM 6.1 Linux drivers. • RAID firmware and BIOS firmware upgrade/downgrade require system reboot for new firmware version to take effect. • If you performed a L2 Upgrade on any CUCM 6.1 or later releases, RAID firmware and BIOS firmware will be upgraded automatically to match with the CUCM version. • If you performed a L2 Fallback from a CUCM 6.1 partition to a CUCM 5.x partition, RAID firmware or BIOS firmware will not be downgraded automatically to match with CUCM 5.x. You need to use a Firmware Leveling CD for 5.x to perform L2 Fallback. • CUCM 6.1 Recovery CD will apply the matching RAID firmware and BIOS firmware and settings with the CUCM release on that partition during partition switching. • Any fallback from CUCM 6.1 release to Windows release are not affected by this framework, because they do not have L2 fallback. It requires a W1 fallback, which is essentially a fresh install of Windows version of CUCM, hence that takes care of firmware leveling implicitly.

Determine IP Phone Firmware Upgrade Strategy

Upgrade IP Phone firmware before CUCM 6.1 Migration
• Best Practice is to separate IP Phone Firmware upgrade from CUCM 6.1 Migration. • Install CUCM 4.x Device Pack to match with CUCM 6.1 Firmware target code before migration to avoid IP Phone firmware download during CUCM 6.1 Migration.

Upgrade IP Phone Firmware during CUCM 6.1 Migration
• Allow Publisher, TFTP, and Backup Subscribers database replication to complete before shutdown Primary Subscriber for 6.1 Migration. It could take up to 2 hours for the database replication to complete. • Upgrading IP Phone Firmware during CUCM 6.1 Migration will generate a lot of TFTP download traffic, shutdown Primary Subscriber server one at a time and leave at least 10 min. in between to avoid mass firmware download from TFTP Server.

Conduct CUCM 4.x to 6.1 Migration Lab Tests
Why perform Migration Lab Tests
The purpose of performing CUCM 4.x to 6.1 Migration Lab tests is to ensure the success of migration. Migration Lab Tests can identify CUCM server hardware compatibility issues, Server Operating Systems Requirement issues, CallManager configuration issues, SQL Database issues, DC Directory Issues, and third party program installed that could conflict with DMA issues. Allow your Migration Team to be familiar with the Migration Process. Test Software Compatibility with other Cisco Unified Communications Applications deployed including CER, CUCCX, Unity, etc. Develop specific Pre-CUCM 6.1 Migration Checklist for your Cluster. Perform Administration Staff Training on the new CUCM 6.1 in the Lab and update your Operations Support and Maintenance procedure.

Conduct CUCM 4.x to 6.1 Migration Lab Tests
How to build a Migration Lab Test Bed
Use an exactly the same server in the Lab as production Publisher with pulled hard disk set from Production Publisher. This is the best option since it can test for both hardware and software compatibility issues. Use a compatible server in the lab and build test bed with BARS backup from Production Publisher server. This option can only test for software compatibility, but not for hardware compatibility. Purchase all new servers and you are planning to replace production CallManager servers with these new servers during Migration. You use BARS to build CUCM 4.x Cluster and to run the entire Migration Process. This option would be the best method for migration since you can pre-install the CUCM 6.1 Cluster and simply cut-over all devices during Migration.

CUCM 6.1 Disaster Recovery System (DRS)
Cisco Disaster Recovery System (DRS), which can be invoked from Disaster Recovery System GUI Web Interface, provides full data backup and restore capabilities for all servers in a CUCM 6.1 cluster. The Cisco Disaster Recovery System performs a cluster-level backup, which means that it collects backups for all servers in a Cisco CallManager cluster to a central location and archives the backup data to physical storage device. The Cisco Disaster Recovery System allows you to perform regularly scheduled or user-invoked data backups. DRS supports only one backup schedule at a time. The Cisco Disaster Recovery System contains two key functions, Master Agent (MA) and Local Agent (LA). The Master Agent coordinates Backup and Restore activity with all the Local Agents. The system automatically activates both the Master Agent and the Local Agent on all nodes in the cluster , but you can only access the Master Agent functions from the First Node or Publisher.

CUCM 6.1 Migration Best Practices

Install First Node (Publisher) first • Boot up from CUCM 6.1 installation DVD • Have information ready before answering questions • Takes < 1hr w/ empty Database, < 2hrs for 5000 Devices. Install Multiple Subsequent Nodes in parallel • Use Answer File for Subsequent Node Installation • Each Subscriber will initiate a DB sync with the publisher • Takes less than one hour for each Subsequent Node to install You must configure a Subsequence Node on the First Node before installing the Subsequence Node. Each Database sync will impact performance, so limit the number of Nodes to 4 in parallel installation. Do not make any configuration changes on during the Migration

If network connectivity test fails, the system always stops and allows you to go back and re-enter the parameter information. Have an USB key ready for diagnostic information dump in case of upgrade failure. You must configure an SMTP Server information in order to use certain Operating System Alert and Notification features. You must reset the Database Replication when revert the cluster to an older release. (execute utils dbreplication reset all on Pub)

CUCM 6.1 Migration Best Practices

Do not install CUCM in a large Class A or Class B subnet that contains a large number of devices. (1024 max ARP entry) Ensure that you connect each CUCM node to an Uninterruptible Power Supply (UPS) to provide backup power and protect your system. Be aware that directory names and filenames that you entered while you are running the installation program are case-sensitive. After CUCM 6.1 Migration, Hostname and Operating Systems Administrator name can not be changed. DNS is highly recommended for CUCM 6.1 deployment.

CUCM 6.1 Migration Best Practices

Do not use User created Profile from the Log out Profile, or it will become the permanent phone settings after CUCM 6.1 migration. If service parameters or product-specific information does not appear in the administration window, execute the CLI command run loadxml and you may need to restart some CCM services. Time required for Disk Mirroring, MCS-7845I1 and MCS-7835I1 servers with 72GB will take 4 hrs per mirror set; MCS-7825I3 with 160GB hard disk will take 3 hrs to mirror the drive. Cisco recommends that you do not delete any node that has CUCM running on it, deactivate the services that are active on that node before deleting it. Minimum Memory Requirement for RTMT Client is 128MB.

CUCM 6.1 Migration Best Practices
NTP Best Practices for CUCM 6.1 Migration
Cisco recommends that you use external NTP Server to ensure accurate system time on the First Node. Ensure the External NTP Server is Stratum 9 or higher (meaning Stratums 1 to 9). If you are getting the system time from a NTP server, verify that the First Node (Publisher) can synchronize with the NTP Server before you install a Subscriber Node. All Subsequence Nodes in the cluster get their time from the First Node. If the First Node fails to synchronize with the NTP server, installation of a Subsequence Node can also fail. To verify NTP Status of the First Node, use the CLI command utils ntp status.

CAR and CDR Database Migration Considerations

If Call Detail Records are not to be migrated to CUCM 6.1:
• All CDR’s should be purged prior to running Cisco DMA • Purge database from CAR using Purge option under System Menu • If running a third party billing program, make a manual CDR backup from SQL database before disconnecting the billing software.

If Call Detail Records are to be migrated to CUCM 6.1:
• Install CAR on CUCM 4.x Publisher before running Cisco DMA

CUCM 6.1 Operations Best Practices
Restart all CUCM servers after security password is changed. Configure Application Users, rather than End Users to access remote nodes to perform such tasks as starting and stopping services. Do not remove the Administrator that was created during CUCM installation or upgrade, or communications with the remote nodes via Serviceability Administration to fail. Create Subdirectories on SFTP Server for each 6.1 Cluster:
ClusterName \DRS \CDR \LOG \TAR \COP for DRS Backup Files for CDR Files from each CUCM Server for Log file download from CUCM server for DMA, Software Upgrade, ES Load, etc. for Firmware, Dial Plan, Locale, etc.
