Hi All,
We planned to upgrade CUCM cluster to 8.6 from 7.1.5.We have 10 servers in the cluster.
My current publisher & some of the subscriber will not compatible with CUCM 8.6.So we have to follow bridge upgrade.
When i upgrade my publisher to 8.x version ( to support DRS in UCS) before collect the DRS whether we have to upgrade all the Nodes to 8.x ?
DRS only collect the backup from active Node.When i collect the back-up only from publisher & upload it UCS is going cause any loss of data ?
Please suggest.
Path 1 :
1) Install the 7.1.5 Publisher on bridge upgrade hardware
2) Restore the 7.1.5 DRS on bridge upgrade hardware
3)Upgrade the Publisher to 8.X
4)Take the DRS
5) Install the 8.X on UCS
6) Restore the 8.X DRS
7) Install all other Servers directly on UCS
Path 2 :
1) Install the 7.1.5 Publisher on bridge upgrade hardware
2) Restore the 7.1.5 DRS on bridge upgrade hardware
3)Replace the Subsciber with bridge upgrade hardware to support 8.x
4)Upgrade the Publisher to 8.X
5) Upgrade all other Nodes to 8.X ( Cluster)
6) Take the DRS
7) Install the 8.X on UCS
8) Restore the 8.X DRS
9) Install all other Servers directly on UCS
If path 2 is supported one i have to use bridge hardware for nodes which all not supported for 8.X
Thanks in Advance

Hi Gpsriramdc,
Please refer the below link, and the section "Bridge Upgrade",
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cucos/8_6_1/cucos/iptpch7.html#wp1119088
Also please refer the below link on "Replacing a Single Server or Cluster for Cisco Unified Communications Manager Release 8.6(1)"
http://www.cisco.com/en/US/partner/docs/voice_ip_comm/cucm/install/8_6_1/cluster/clstr861.html
Procedure
Step 1 Perform an upgrade to the new Cisco Unified Communications Manager version on your discontinued first node (publisher) server. Refer to the preceding sections in this chapter that describe the kind of upgrade you want to do. Observe the warning on the console that tells you that the only thing you can do with the new Cisco Unified Communications Manager version is to perform a DRS backup ("This hardware has limited functionality. Backup and Restore is the only supported functionality.").
Step 2 Perform an upgrade to the new Cisco Unified Communications Manager version on your subsequent node (subscriber) servers. Refer to the preceding sections in this chapter that describe the kind of upgrade you want to do.
Step 3 Verify database synchronization between all nodes. You can use the CLI commands utils dbreplication runtime state and utils dbreplication status. For more information, refer to the Command Line Interface Reference Guide for Cisco Unifed Communications Solutions.
Step 4 Using the new Cisco Unified Communications Manager version on your discontinued first node server, perform a DRS backup. The DRS backups are encrypted using the cluster security password provided at install time. You must remember this security password as the "old" password, because you may be prompted to enter this "old" password at the time of restore. Refer to the Disaster Recovery System Administration Guide.
Step 5 Disconnect your discontinued server from the network.
Step 6 Install the new Cisco Unified Communications Manager version on your new supported first node server. You must obtain and install a new license on this server. Refer to the guide Installing Cisco Unified Communications Manager. You will be prompted to enter a "new" security password, a password that is different from the "old" password you noted in Step 4. The guide Installing Cisco Unified Communications Manager describes the requirements of a "new" security password that Cisco Unified Communications Manager will accept. You must remember this "new" security password.
Step 7 Using the new Cisco Unified Communications Manager version on your new supported first node server, perform the Disaster Recovery System Administration Guide procedure "Restoring the First Node only (Rebuilding the Publisher Alone)". First, select only select the first node for restore. You can only select the subsequent nodes for restore after the completion of first node restore. Use the discontinued server's backup file that you created in Step 4. You will be prompted for the "old" security password that you noted in Step 4. For further details, refer to the Disaster Recovery System Administration Guide.
Step 8 On your new supported first node server, reactivate all services that used to be active on your discontinued first node server before the bridge upgrade. Refer to the Administration Guide for Cisco Unity Connection Serviceability.
Step 9 Verify database synchronization between all nodes. You can use the CLI commands utils dbreplication runtime state and utils dbreplication status. For more information, refer to the Command Line Interface Reference Guide for Cisco Unifed Communications Solutions.

Hi Anand,
Thanks for the Info. I need some more clarifications.
My Pub is MCS7845I2-K9-CMB1 which is having 72 GB HDD , 4 GB RAM. This server not support for 8.6 & having insufficient memory.
When i install the 8.6 it will detect hardware type & considerd as bridge upgrade ?
If it support to install 8.6 whether we have to follow the same instructions as like RU procedure.
Thanks.

Hi Gpsriramdc,
Please refer the below link, please look out for "MCS7845I2-K9-CMB1" and in the column "Cis-co Uni-fied CM 8.6(x)", which has B(5), which means as stated below.
• "B" means the server is only supported for "bridged upgrade," as described in footnote 5
(5) Supported only for "bridged upgrade" to migrate to newer hardware. In a bridged upgrade, you upgrade to the specified Cisco Unified Communications Manager version, make a backup of your software configuration via the Disaster Recovery System utility, reinstall the Cisco Unified Communications Manager version on new hardware, and restore your software configuration from backup. This server is not supported for any other use with Cisco Unified Communications Manager other than this "bridged upgrade" procedure.
