Review the Planning chapter. Make sure to review the following:

• Decide on your Unified CM and IM and Presence Service cluster Topology.

• Decide on the Hypervisor version that you want and its supported hardware.

• Pick an installation method supported by Hypervisor.

Review the installation requirements and record the configuration settings for each server that you plan to install.

• Get base OVA. An example OVA file name is: cucm_15_all_esxi_vmv17_or_nfvis_v1.0.sha512.ova.

  Note

  From Release 15 onwards, the OVA template is signed with sha512 using Cisco authenticated certificates to ensure that there is no tampering of the OVA file. To avoid seeing the "The certificate is not trusted" warning when using the OVA to create a new Virtual Machine, use the following steps: Navigate to https://www.cisco.com/security/pki/codesign/. Download the Issuer Chain PKCS7 (PEM) file (right-click and choose Save link as) for the selected certificate that is used to sign the OVA file. The signing certificate used is documented in the File Information of the downloaded OVA page. Add these certificates to vCenter by following the steps in the 'Resolution' section at: https://kb.vmware.com/s/article/84240.

For more information, refer to the technical documentation on Broadcom.com.

Place the installation ISO file in a location where the virtual machine can access it and edit the virtual machine's DVD drive to map to the file. Select the option to mount the DVD drive when you power on the virtual machine.

When you power on the virtual machine, it mounts the ISO file and start the installation process. Do not begin the installation process until you have completed all the steps in this procedure.

For more information, refer to the technical documentation on Broadcom.com.

• Decide on your Unified CM and IM and Presence Service cluster Topology.

• Decide on the Hypervisor version that you want and its supported hardware.

• Pick an installation method supported by Hypervisor.

Review the installation requirements and record the configuration settings for each server that you plan to install.

An example OVA file name is: cucm_15_all_esxi_vmv17_or_nfvis_v1.0.sha512.ova.

Upload the OVA as a profile and the ISO as an image together. This process creates a separate profile for each VM configuration and a single image for the bootable ISO. For more information, refer to the 'Image Registration for CUCM Applications' section in the Cisco Enterprise Network Function Virtualization Infrastructure Software Configuration Guide.

1. Ensure that an OVA and ISO image is already uploaded.

2. Navigate to Configuration > Deploy.

3. Select OTHER as the option when creating virtual machines for your application type.

4. Connect to the virtual network and assign the Image/Profile (depending on the deployment size that you prefer), and click Deploy.

5. Open the VM console via Configuration > Virtual Machine > Manage.

6. Use the console to complete the ISO installation process.

• Decide on the Unified CM and IM and Presence Service cluster Topology.

• Decide on the Hypervisor version that you want and its supported hardware and hyperconvergence software version.

• Pick an installation method supported by Hypervisor.

Review the installation requirements and record the configuration settings for each server that you plan to install.

An example OVA file name for a large size deployment is: cucm_15_large_ahv_v1.0.sha512.ova.

1. Download the Unified CM .ova files based on the required configuration from the Software Download page .

2. Upload the Unified CM .ova files (downloaded) onto the Nutanix cluster using Prism Central.

3. Download the desired Unified CM bootable .iso image version from the Software Download page and upload the image to the Nutanix cluster.

4. Creating Unified CM Publisher and Subscriber VMs using the .ova files.

5. Update Unified CM VMs to mount CD-ROM with the Unified CM image.

Review the Planning chapter. Make sure to review the following:

• Decide on your IM and Presence Service and Unified CM cluster Topology.

• Decide on the Hypervisor that you want and its supported hardware.

• Pick an installation method supported by Hypervisor.

Make sure that the Unified Communications Manager and IM and Presence Service software versions are compatible.

Gather all the information you need to complete the installation and configuration of the IM and Presence Service.

For every node in your cluster, create virtual machines using the Virtual Server Template (OVA file) that is recommended for your release. An example OVA file name is: imp_15_all_esxi_vmv17_or_nfvis_v1.0.sha512.ova.

Different OVA files are available; choose the correct OVA file based on the environment in which you are deploying Unified Communications Manager. See Virtualization Requirements.

Make sure that each IM and Presence Service server has network access to the Unified Communications Manager publisher server. Ping the Unified Communications Manager publisher node from the other IM and Presence Service servers.

• Decide on your IM and Presence Service and Unified CM cluster Topology.

• Decide on the Hypervisor version that you want and its supported hardware.

• Pick an installation method supported by Hypervisor.

Review the installation requirements and record the configuration settings for each server that you plan to install.

An example OVA file name for a medium sized deployment is: imp_15_medium_ahv_v1.0.sha512.ova .

1. Download the IMP.ova files based on the required configuration from the Software Download page.

2. Upload the IMP.ova files (downloaded) onto the Nutanix cluster using Prism Central.

3. Download the desired IMP bootable .iso image version from the Software Download page and upload the image to the Nutanix cluster.

4. Creating IM and Presence Service Publisher and Subscriber VMs using the .ova files.

5. UpdateIM and Presence Service VMs to mount CD-ROM with the IM and Presence Service image.
