Increase VM resource to Unity Connection and Im&Presence

[asafgo616]

Hello,

I have Unity Connection and Im&Presence in Ver: 11.5.1.11900

2 Unity Servers and 2 Presence servers.

The VM installed with the resource:

VM	CPU	Memory	Disk	Users
Im&Presence	2 vCPU	4 GB	80GB X2	5,000
Unity Connection	1 vCPU	4 GB	160GB	1,000

Now i need to increase the resource to:

VM	CPU	Memory	Disk	Users
Im&Presence	4 vCPU	8 GB	80GB X2	15,000
Unity Connection	2 vCPU	6 GB	200GB	5,000

I saw in "Supported Platforms List" doc that:

Caution

Changing the number of virtual CPUs, the amount of virtual RAM, or the number or size of virtual disks is not supported.

What is the best practice to increase resource in this VM's?

Thanks,

Whenever you need to adjust the OVA deployment, you can always perform a DRS backup of the application, deleted the VM from ESXi, and rebuild the entire server with the new OVA template and size, finishing with a restore from the DRS backup.

Here is the process documentation for DRS Backup/Restore in CUC.

Hi Anthony,

There is another way? Like shutting down the VM, Change VM settings and starting the VM?

Thanks,

Hi all,
To the Unity Connection servers - I will backup and restore to a new OVA.

To Im&Presence Server - I look in the Cisco Docs, I saw a Procedure in "Upgrade and Migration Guide":

- To change the vCPU, make the change in vSphere Client. Ensure that you change the reservation value to match the specifications of the new release.

- To change the vRAM, make the change in vSphere Client. Ensure that you change the reservation value to match the specifications of the new release.

- To increase the vDisk space, edit the storage size using vSphere Client. If the virtual machine has two disks, expand the second one.

Update:
I Backed up and restore the Unity, and Increae the Resource on Vsphere cliect to Presence Servers - it's work perfect.
