You can migrate the Panorama configuration from an M-100 or M-500 appliance to a Panorama virtual appliance in Panorama mode. However, you cannot migrate the logs because the log format on the M-Series appliances is incompatible with that on the Panorama virtual appliances. Therefore, if you want to maintain access to the old logs stored on the M-Series appliance, you must continue running the M-Series appliance as a Dedicated Log Collector after the migration and add it to the Panorama virtual appliance as a managed collector. The M-Series appliance will continue to collect the new logs that firewalls forward after the migration.
Migrate from an M-Series Appliance to a Panorama Virtual Appliance
Plan the migration. Determine the required software version of the Panorama virtual appliance. Upgrade the software on the M-Series appliance before the migration if the Panorama virtual appliance requires a more recent Panorama release (the M-500 appliance requires Panorama 7.0 or a later release). For important details about software versions, see Panorama, Log Collector, and Firewall Version Compatibility. Schedule a maintenance window for the migration. Although firewalls can buffer logs after the M-Series appliance goes offline and then forward the logs after the Panorama virtual appliance comes online, completing the migration during a maintenance window minimizes the risk that logs will exceed the buffer capacities and be lost during the transition between Panorama models.
Purchase the licenses for the new Panorama virtual appliance. Get the auth-code for the Panorama virtual appliance and the support license. Provide your sales representative the serial number of the M-Series appliance you will phase out, the auth-code you received when you purchased the new Panorama virtual appliance, and the effective date for the migration. On the effective date, Palo Alto Networks will automatically apply the existing auth-code to the serial number of the Panorama virtual appliance, apply the new management license to the M-Series appliance, and trigger support for the M-Series appliance. Consult your sales representative regarding how much time is available to complete the migration after the effective date.
Export the configuration from the M-Series appliance. Log in to the M-Series appliance and select Panorama > Setup > Operations. Click Save named Panorama configuration snapshot, enter a Name to identify the configuration, and click OK. Click Export named Panorama configuration snapshot, select the Name of the configuration you just saved, and click OK. Panorama exports the configuration to your client system as an XML file. Save the configuration to a location external to the Panorama appliance.
Power off the M-Series appliance if you won’t need to access to it after the migration or assign a new IP address to its management (MGT) interface if you will need access to it. To power off the M-Series appliance: Log in to the Panorama web interface. Select Panorama >Setup > Operations and under Device Operations, Shutdown Panorama. Click Yes to confirm the shutdown. To change the IP address on the M-Series appliance: Log in to the Panorama web interface. Select Panorama > Setup > Management, and edit the Management Interface Settings. Enter the new IP Address and click OK. Select Commit > Commit to Panorama and Commit your changes.
Perform the initial setup of the Panorama virtual appliance. T o manage your firewalls and resume log forwarding, you will need to assign the MGT interface of the Panorama virtual appliance the same IP address as the original MGT interface of the M-Series appliance during the initial configuration of the Panorama virtual appliance. Set Up the Panorama Virtual Appliance. Perform Initial Configuration of the Panorama Virtual Appliance to define the network connections required to activate licenses and install updates. Register Panorama. Activate a Panorama Support License. Activate/Retrieve a Firewall Management License on the Panorama Virtual Appliance. Install Content and Software Updates for Panorama. Install the same versions as those on the M-Series appliance.
Load the Panorama configuration snapshot that you exported from the M-Series appliance into the Panorama virtual appliance. Log in to the Panorama web interface of the Panorama virtual appliance, and select Panorama > Setup > Operations. Click Import named Panorama configuration snapshot, Browse to the Panorama configuration file you exported from the M-Series appliance, and click OK. Click Load named Panorama configuration snapshot, select the Name of the configuration you just imported, select a Decryption Key (the master key for Panorama), and click OK. Panorama overwrites its current candidate configuration with the loaded configuration. Panorama displays any errors that occur when loading the configuration file. If errors occurred, save them to a local file. Resolve each error to ensure the migrated configuration is valid. The configuration has been loaded once the commit is successful.
Modify the configuration on the Panorama virtual appliance. Required if the Panorama virtual appliance will use different values than the M-Series appliance. Select Panorama > Setup > Management. Edit the General Settings, modify the Hostname, and click OK. Edit the Management Interface Settings, modify the values as necessary, and click OK.
Set up the M-Series appliance as a Dedicated Log Collector and add it as a managed collector on the Panorama virtual appliance. Loading the configuration from the M-Series appliance ( Step 6) removes the default managed collector and Collector Group that are predefined on each M-Series appliance. Power on the M-Series appliance. Set up the M-Series Appliance as a Log Collector. Configure a Managed Collector on the Panorama virtual appliance. Configure a Collector Group on the Panorama virtual appliance for the default managed collector. Select Commit > Commit to Panorama and Commit your changes to the Panorama configuration.
Synchronize the Panorama virtual appliance with the firewalls to resume firewall management. Complete this step during a maintenance window to minimize network disruption. On the Panorama virtual appliance, select Panorama > Managed Devices and verify that the Device State column displays Connected for the firewalls. At this point, the Shared Policy (device groups) and Template columns display Out of sync for the firewalls. Push your changes to device groups and templates: Select Commit > Push to Devices and Edit Selections. Select Device Groups, select every device group, Include Device and Network Templates, and click OK. Push your changes. In the Panorama > Managed Devices page, verify that the Shared Policy and Template columns display In sync for the firewalls.
