After Upgrading ClearPass to 6.7.0 on Hyper-V Servers

If you are upgrading ClearPass from 6.5.x or 6.6.x to 6.7.0 on a Hyper-V server, additional steps are required after the upgrade.

ClearPass 6.5.x and 6.6.x Hyper-V images were shipped with network adapters of type “Legacy Network Adapter”. CentOS version 7 does not support the Legacy Network Adapter type, therefore ClearPass 6.7.0 Hyper-V images do not support the Legacy Network Adapter type. After upgrading from ClearPass 6.5.x or 6.6.x to 6.7.0, you must follow the steps below in order for ClearPass to have network connectivity:

1. After you upgrade to 6.7.0, log in to the console as appadmin, and use the CLI command <system shutdown> to shut down the ClearPass server. This step must be done only through the console.
2. After the command is executed, wait for the virtual appliance to shut down completely.
3. Edit the ClearPass virtual appliance settings in the Hyper-V manager and remove all three network adapters (these are named NIC0, NIC1, and Network Adapter).
4. Add two new network adapters with names of type Network Adapter.
5. Edit the network adapters. Make the first one the management port connected to SwitchManagement, and make the second one the data port connected to SwitchData.
6. Save the new settings and start the ClearPass virtual appliance.
7. Log in to the ClearPass console using the appadmin account, and then run the following CLI command to refresh the network settings:

system refresh-network

8. After the refresh command is executed, reboot the ClearPass virtual appliance to establish network connectivity.


Do not use the Cluster Upgrade Tool to upgrade ClearPass clusters from 6.5.x or 6.6.x to 6.7.0 on a Hyper-V server. Doing so will cause the appliance to lose network connectivity after the upgrade and will require manual intervention from the administrator to regain connectivity.
