A. CUCM 9.0 is also supported on MCS servers, please check the below URL for details on what servers support CUCM 9.0
A. Yes, CUPS needs to be upgraded to 9.1 as well, starting with ver 9.X. CUCM, IM & Presence version numbers need to be in sync.
A. Unity is EoS, so as such it is recommended to upgrade to Unity Connection.
A. Currently no automated Tool is available for upgrade. There are plans to introduce it in ver 10.X
A. You could use CUCM User Count Tool (UCT) for planning the licenses -
A. Have a look at this URL, it has a presentation on license migration - https://supportforums.cisco.com/community/netpro/collaboration-voice-video/ip-telephony/blog/2013/05/20/drive-to-9
A. Have a look at the supported server model for CUCM, that should provide info on which servers support Bridge mode -
A. There are different upgrade options available starting CUCM 9.1.2, we will be covering that in the PPT, you may also use the Upgrade Assessment Tool which provides the relevant documentation depending on From/To version. Stay tuned for demo ahead
A. It will help you in planning for licenses. Since licensing changes in 9.1, you can use this utility to find out how many Enhanced, CUWL or relevant licenses are required.
A. Unity is EoS, consider upgrading to Unity Connection. Use this url for more on Unity - CM Compatibility
A. Have a look at CUCM Software Compatibility Matrix.You may need to move to CME 9.0
A. ELM is Enterprise License Manager, basically a centralized pool for licensing for CUCM + CUC. This is available starting CUCM 9.0
A. You have to just open a case, give your requirement and the Licensing Team will get licenses for you. However we recommend that you add all un-used licenses prior to upgrade.
A. With CUCM 9.0 we have introduced ELM and licensing has changed, visit this page for a presentation on licensing migration - https://supportforums.cisco.com/community/netpro/collaboration-voice-video/ip-telephony/blog/2013/05/20/drive-to-9
A. Jump Upgrade only available + supported from CUCM 9.1.2. Doing a Jump Upgrade on prior versions is not supported by TAC.
A. CUE 8.6.6 should work with CUCM 9.1. I recommend you keep an eye on this document -
A. You need to use the User Count Tool (UCT) to find out the CUWL, UCL licenses you need pro-actively.
A. We have User Count Tool (UCT) available for planning the licensing needs -
A. ATA186 is really old. It is EoS, I recommend moving to ATA187 or VG20x XM instead. As per CUCM Software Compatibility Matrix, ATA186 isn't listed.
A. One can use the “Prepare Cluster for Rollback to pre-8.0” enterprise parameter to download empty ITL files in the cluster(follow the documented process). Once the empty ITL file has been downloaded, the phone will accept any ITL file coming its way next. Now you can move this set of phone to another cluster & set the enterprise parameter back to false.
A. Yes, it considers the unused DLUs and it displays the unused DLUs. UCT is not going to give any licenses. It helps us to see how many DLUs are going to look like in the form of UCL/CUWL. UCT Tool pulls up DLU information and then you can calculated add or subtract your licenses. You can use the UCT tool to make a decision on how many licenses of what kind you are going to request from the licensing Team. This is just going to help us make a decision and it show you a picture of how your license lok like in ELM mode.
A. Upgrade Readiness Assessment is available for use. However continuos enhancements are made to the tool.
A. Extension Mobility has been removed as a licensed user feature in Cisco Unified Communications Manager 9.1(1a). Users that have only Extension Mobility configured no longer require an Essential license. Extension Mobility is configured when a device profile is entered for Extension Mobility in the End User Configuration.
A. We recommend using the upgrade readiness assessment tool. It shall let you know the best migration path to take.
A. Jump Upgrade is available + supported starting 9.1.2. Earlier versions are not supported by TAC
A. You can use license count utility to plan licensing and request licenses. Migration of CUCM License is a manual process and there is a need to contact GLO (Global Licensing Office) team with the UCT output and contract details.
A. If you are migrating from a hardware 8.6 to 9.1 on UCS, you can defintely do an upgrade on existing callmanager template the way its deployed for 9.1 and then take a DRS backup of 9.1 callmanager but when you actually deploy 9.1 you have to rebuild the system based on 9.1 using the template and then restore the backup.We will help to use the new template defined for 9.1.
A. CUPS needs to be migrated to IM/Presence 9.1 too and RCC would still be supported
A. 8.5 - 9.1 is a 1-step upgrade right. Refer to Upgrade paths on this URL -
A. CUCM 8.0.3 was the first release to support Virtualization on UCS. For 3rd Party Specs-Based support, I believe it was added in 8.6
A. It is very similar to a regular cop file install and requires no IMM credentails. However you would need access to CUCM to install cop file.
A. ELM can co-reside with CUCM.
A. Change of IP will require CTL file to be updated.
A. Refer to this URL on features available in different licensing options -
A. ELM doesn't support redundancy at the moment, so no clustering. However, ELM can be backedup.
Also, you have a 60 day grace period with full functionality if your ELM server goes offline.
A. Refer to Supported Upgrade paths here -
A. Use the license count tool to plan the licenses for 9.1. This can be done without upgrading to 9.1. Also, by providing the appropriate details to the licensing team, CUCM 9.1 licenses would be issued.
A. Co-resident ELM and Standalone ELM are both possible. However, for multiple clusters, we recommend Centralized ELM for easier management.
A. More on jump upgrade will be available once 9.1.2 is FCS
A. You may want to upgrade your current server to 9.1 (if it supports it) then move to Virtual environment using DRS restore
A. CUCM 9.1.2 is not FCS'd, so don't know the default phone firmware that will be available with this version. Also, we need to wait and check the support for older phone models.
A. Refer to New & Changed information in release notes -
A. Upgrade from 5.x may require multiple hops. You may need to upgrade to 6.1.4 or 6.1.5 before you could consider jump upgrade
A. We recommend a cluster backup & restore. Yes, all servers need to be backed up and restored.
A. Most likely isolated network would require LDAP. I recommend watch out for 9.1.2 Jump Upgrade documentation post 9.1.2 FCS for more details
A. We are targetting early August 2013 for FCS. However this date is not set in stone.
A. Here it is -
A. If License MAC changes, you need to re-host the license. You get a 30 day timeframe to do that. this has changed with 9.0 as we introduced ELM
A. Jump Upgrade is TAC supported starting 9.1.2
A. Refer to CUCM Compatibility Matrix -
A. Depending on your hardware model. 7.1.3 - 9.1.2 should be direct 1-step. Check this url -
A. Yes, introduced & TAC supported from 9.1.2 only.
A. We are targetting early August 2013. However this date is not set in stone. We believe the code would be available globally.
A. UCT should function with 5.x too.
A. Yes you can upgrade RAM/HDD, however they need to be procurred from HP directly as MCS 7845 H2 is EOS. Refer to supported server for CUCM doc -
A. Recommended to restore Subscribers also.
A. Most likely yes.
Q. Will the presentation be available for download or later review?
A. Yes, it will be available so that you can review and download.
