How can I safely increase the disk size of the Ops Manager VM?

Resolution

To safely increase the disk size of the Ops Manager VM, follow these steps: 

1. Export the installation settings from your current Ops Man. This can be done from the Ops Man GUI: Admin -> Settings -> Export Installation Settings.  Save this file as this will be used in a later step.
2. In your IaaS, create a new VM with a larger disk.  Deploy the Ops Manager OVA to vCenter with the same vApp properties (ip,netmask,gateway,DNS,ntp_servers,public_ssh_key,custom_hostname) as the current one.  Once it is deployed, and while powered off, right-click the VM and click "Edit Settings", and then update the size of "Hard disk 1" to desired number.  Save the changes. Do not power on yet.
3. Power off your current Ops Man VM (do not delete it, just leave it powered off).
4. Power On the new VM.  Once you see that the IP address has been assigned (in vCenter VM page), navigate to the Ops Manager URL in your browser, and then you should see the "Welcome" page.  Select "Import Existing Installation", and then upload the installation file (exported in step 1).  Enter your Decryption Passphrase. Click "Import".
5. Once the import is successful, log in.  Go to the BOSH Director Tile -> Status tab to ensure it sees the updated environment.  Run Apply Changes,
6. Once this is complete and working, keep the powered off old VM as a backup in the environment for a couple of days/weeks, or follow your own internal policies with regards to old VMs.
