Before You Begin
Make sure you have enough available space on the Manager for all appliance SWU files that you upload to Update Manager. Also, confirm you have enough available space on each individual appliance.
Check the Available Disk Space
Use these instructions to confirm you have enough available disk space:
- Log in to the Appliance Admin interface.
- Click Home.
- Locate the Disk Usage section.
- Review the Available (byte) column and confirm that you have the required disk space available on the /lancope/var/ partition.
• Requirement: On each managed appliance, you need at least four times the size of the individual software update file (SWU) available. On the Manager, you need at least four times the size of all appliance SWU files that you upload to Update Manager.
• Managed Appliances: For example, if the Flow Collector SWU file is 6 GB, you need at least 24 GB available on the Flow Collector (/lancope/var) partition (1 SWU file x 6 GB x 4 = 24 GB available).
• Manager: For example, if you upload four SWU files to the Manager that are each 6 GB, you need at least 96 GB available on the /lancope/var partition (4 SWU files x 6 GB x 4 = 96 GB available).
The following table lists the new patch file sizes:
| Appliance | File Size |
| Manager | 5.7 GB |
| Flow Collector NetFlow | 2.6 GB |
| Flow Collector sFlow | 2.4 GB |
| Flow Collector Database | 1.9 GB |
| Flow Sensor | 2.7 GB |
| UDP Director | 1.7 GB |
| Data Store | 1.8 GB |

Smart Licensing Changes
We have changed the transport configuration requirements for Smart Licensing.
If you are upgrading the appliance from 7.4.1 or older, make sure that the appliance is able to connect to smartreceiver.cisco.com.
Known Issue: Custom Security Events
When you delete a service, application, or host group, is it is not deleted automatically from your custom security events, which can invalidate your custom security event configuration and cause missing alarms or false alarms. Similarly, if you disable Threat Feed, this removes the host groups Thread Feed added, and you need to update your custom security events.
We recommend the following:
- Reviewing: Use the following instructions to review all custom security events and confirm they are accurate.
- Planning: Before you delete a service, application, or host group, or disable
Threat Feed, review your custom security events to determine if you need to update them.
1. Log in to your Manager.
2. Select Configure > DETECTION Policy Management.
3. For each custom security event, click the (Ellipsis) icon , and choose Edit. - Reviewing: If the custom security event is blank or missing rule values, delete the event or edit it to use valid rule values.
- Planning: If the rule value (such as a service or host group) you are planning to delete or disable is included in the custom security event, delete the event or edit it to use a valid rule value.
