Hi Raees, 

 

Thanks for the video it looks very amazing tool, one of my client is going to upgrade from CUCM 6.1.2 (MCS) cluster to 10.x (B-Series) cluster

I just want to clarify couple of things - 

- Do i need to upgrade from 6.1.2 to 6.1.5 

- As part of the new license order client has "PC-10X-Standard-K9 - Cisco Prime Collaboration Standard 10.x" is this license sufficient for migrating from 6.x to 10.x. or any other license is required. 

 

Thanks,

Kazim

Hi Kazim

Yes, you would need to upgrade the customer CUCM system from CUCM ver 6,.1.2 to CUCM ver 6.1.5 before starting the migration using PCD to CUCM ver 10.x. 

As far as the license is concerned, the PCD software is shipped along with the CUCM 10.x bootable image & does not require any license for performing tasks like migration etc.

Hi Rashaikh,

 

Where can I get  OVA PCD? I have to upgrade CUCM 9.1 to 10.X on a BE6K platform.

I've seen the following on Cisco FieldTrainers channel on Youtube.

pcd_vApp_UCOS_10.0.1.10000-13_vmv7_v1.0.ova

 

Thanks in advance

Hi Jonas

The PCD SW & ova should be shipped along with the CUCM 10.x bootable image.

Hi Raees

PCD looks like a great tool. My issue is the ITL files deletion during the 8.x to 10.x upgrade. Even I had a nightmare on this issue at a customer site, where we went to each phone and deleted the file. My question is the ITL file issue will not hinder us while using PCD. Hope we don't have to delete the itl files from the phones after the migration.

Hi Ratheesh

You won't run into ITL file issue while performing upgrade/migrate task using PCD as it performs a backup of the Private & Public keys from the existing cluster & restores them in the new CUCM 10.x cluster. Therefore, the new ITL file is signed using the same keys & the phones would accept it seamlessly. 

 

Thanks & Regards

Hello...we currently went though a PCD migration to a new cluster (upgraded hardware, changed IPs and hostnames) to perform initial testing prior to a full migration of our production system. I am wondering if there is a way to simply "refresh" the data in the new CUCM environment rather than having to blow everything away and do it again for the actual conversion.

Thanks

Cisco Employee

Hi

You should be able to find the OVA in www.cisco.com downloads section using the following path

Downloads Home > Products > Unified Communications > Call Control > Cisco Unified Communications Manager (CallManager) > Cisco Unified Communications Manager Version 10.0 > Unified Communications Manager Virtual Machine Templates-10.0(1)

Hi Clark

Im not sure if I understand the question correctly. If you are talking about the Vm's you created to test the migration, there is no way to refresh the data & you will have to delete them as per your requirement.

Hi Guys We have following applications running on MCS servers.

1. CUCM 8.5.1 Pub and Sub

2. CUC and UCCX 8.5.1 respectively.

We have ordered two BE6K servers to migrate above applications to release 10. I am planning to use PCD for this and have few questions

1. We are not running CUPS and no plans to run IM&P. Does that mean that i dont need to create an IM&P ova for this migration?

2. PCD doesnt support CUC and UCCX migration at the moment. what is the best approach to have them migrated across to BE6Ks with minimum down time?

3. For licensing, can I install PLM 10 on BE6K in advance of migration? having other VMs running on BE6K shouldn't affect the migration?

4. We do have Vmware foundation licensing ordered with BE6K servers. so I hope PCD works fine there?

5. I can see PCD 10.5 is available. Can I use it to migrate from 8.5.1 to 10.5 directly? Release notes says below

 

For a migration from Release 10.0(1) to Release 10.5(1) to be successful, you must upgrade all source cluster Cisco Unified Communications Manager nodes to 10.0(1)SU1, at a minimum, before using Cisco Prime Collaboration Release 10.5(1) to perform a migration.

 

does that mean that pcd 10.5 is only for migrations from 10 to 10.5?

6. I believe PCD doesnt use DRS at any point so 8.5.1 to 10 shouldnt be affected by CSCtn50405?

what if the IP and hostname is changed as part of migration?

Hi Raees,

We have a CUCM 9.1.2 envirioment with 1 Pub and 1 Sub. Both are appliance model and are running in mixed mode. Most phones are using secure profile. We plan to migrate from appliance model to Vm on UCS using PCD tool.

Q: What about migrating CTL in this case? does PCD take care of everything? What is the proper procedure?

Q: Does PCD take care of ELM migration which is in our case co-resistent on Publisher node?

 

Thank you for info,

Hi Aman

Please find the answers inline

1. CUCM 8.5.1 Pub and Sub

2. CUC and UCCX 8.5.1 respectively.

We have ordered two BE6K servers to migrate above applications to release 10.
I am planning to use PCD for this and have few questions

1. We are not running CUPS and no plans to run IM&P. Does that mean that i
dont need to create an IM&P ova for this migration?

[Raees] If you dont use IM & P, there is no need to create an instance of the same. 

2. PCD doesnt support CUC and UCCX migration at the moment. what is the best
approach to have them migrated across to BE6Ks with minimum down time?

[Raees] Since PCD does not support the migration task for UCCX & Unity Connection, you will have to use the manual method to migrate these two application. 

3. For licensing, can I install PLM 10 on BE6K in advance of migration?
having other VMs running on BE6K shouldn't affect the migration?

[Raees] Yes, you can install a stand alone PLM & install the licenses or after the migration you can use the PLM from one of the applications to manage the licenses. Once you upgrade to UC ver 10, you get a grace period of 60 days to upload the licenses. 


4. We do have Vmware foundation licensing ordered with BE6K servers. so I hope PCD works fine there?

[Raees] Im not sure I got your question right, nevertheless, PCD has nothing to do with UC or Vmware licensing as long as you are able to create a Vm using OVA for PCD & install PCD.

5. I can see PCD 10.5 is available. Can I use it to migrate from 8.5.1 to
10.5 directly? Release notes says below

"For a migration from Release 10.0(1) to Release 10.5(1) to be successful, you
must upgrade all source cluster Cisco Unified Communications Manager nodes to
10.0(1)SU1, at a minimum, before using Cisco Prime Collaboration Release
10.5(1) to perform a migration."

does that mean that pcd 10.5 is only for migrations from 10 to 10.5?

[Raees] No. You can use PCD 10.5 to migrate from CUCM 8.5 to CUCM ver 10.5

6. I believe PCD doesnt use DRS at any point so 8.5.1 to 10 shouldnt be
affected by CSCtn50405?

[Raees] Yes. PCD does not use DRS to perform migrate operation.

Hi Ales

Q: What about migrating CTL in this case? does PCD take care of everything? What is the proper procedure?
[Raees] Although PCD does take a backup of the CTL file & the private/public keys for different roots ex. CAPF, its highly recommended that you re-run the CTL Client after migration. 

Q: Does PCD take care of ELM migration which is in our case co-resistent on Publisher node?
[Raees] In UC ver 10.x & above, ELM has been changed to PLM (Prime License Manager) & you would need ver 10.x licenses to work with UC ver 10.x. You will have to install & migrate ver 9.x licenses to ver 10.x using PLM.
