How do I transition from Lighthouse 4 to Lighthouse 5?

Lighthouse 4 has reached End of Life. This information is for archival purposes only.

Due to the significant architectural differences between Lighthouse 4 and Lighthouse 5, a direct upgrade or migration is not supported. However, Opengear devices support parallel management by Lighthouse 4 and Lighthouse 5, which can be leveraged to smoothly and quickly transition to the new central management platform.

These instructions assume that you already have a Lighthouse 4 running with all Opengear devices (nodes) enrolled, that Lighthouse 5 has been deployed but you are yet to enroll nodes, and that you will be transitioning all Opengear devices.

Process overview

1. Backup node configuration using Lighthouse 4
2. Upgrade node firmware to 4.1.0 or later using Lighthouse 4
3. Create an Enrollment Bundle on Lighthouse 5
4. Start Lighthouse 5 enrollment using Lighthouse 4
5. Optional: Remove managed nodes from Lighthouse 4

Backup node configuration

• Login to the Lighthouse 4 CLI as root or become the root user with: sudo -i - Run the command:

node-command --all --quiet config -e -

• The backup OPG files are saved in the /var/nvlog/nagios/node-command/<username>/stdout/ directory, named by their unique addresses in Lighthouse
• Optional: For convenience, run these commands to copy and rename the .opg backups:

src=$(ls -td /var/nvlog/nagios/node-command/*/stdout | head -n1)
target=/var/nvlog/opg_bak_$(date +%s)
mkdir -p $target
node-info | awk '/^[0-9]:/ { print "cp -a '$src'/"$2" '$target'/"$3".opg" }' | bash

• Copy the backups off box using scp, WinScp or similar

Upgrade node firmware

Note: This step is not supported by legacy Opengear models that do not contain internal mass storage (for example cellular-enabled ACM5000).

• Recommended: Before running the bulk upgrade, manually upgrade and test a single unit first - For each Opengear device model (for example IM7200, ACM7000), download the current firmware from: http://ftp.opengear.com/download/release/current/
• Copy the firmware files to Lighthouse 4 using scp, WinScp or similar, into the directory: /var/nvlog
• Login to Lighthouse 4 as root or become the root user with: sudo -i
• For each Opengear device model, perform a bulk upgrade using the node-upgrade command, for example for IM7200 Infrastructure Managers:

node-upgrade --select-match 'Model=IM72' --deselect-match 'Version=4.1' --firmware-file /var/nvlog/im72xx-4.1.0u2.flash

Note: You can view the available Model information to match on by running: node-info

• This process may take up to an hour to complete

Create an Enrollment Bundle

• Login to the Lighthouse 5 Web UI as a Lighthouse Administrator
• Click Manage -> Configure Nodes -> Node Enrollment -> Enrollment Bundles
• Click + to add a new Bundle:

Bundle name: Enter a name of your choice, for example MigratedNodes
Token: Enter a password of your choice, for example my-secret-token
Auto-approve node: Check

• Click Apply

Start enrollment

• Login to Lighthouse 4 as root or become the root user with: sudo -i
• Run the commands below if the Node firmware is 4.1:

node-command --all config -s config.lhvpn.callhome.address=address.of.lighthouse
node-command --all lhvpn-callhome address.of.lighthouse 443 my-secret-token MigratedNodes

• Run the commands below if the Node firmware is 4.2 or later:

node-command --all config -s config.lhvpn.callhome.address=address.of.lighthouse
node-command --all lhvpn-callhome -a address.of.lighthouse -p 443 -s my-secret-token -m MigratedNodes

• Login to Lighthouse 5 as a Lighthouse Administrator
• Monitor registration and enrollment as nodes progress from Configure Nodes -> Node Enrollment -> Pending Nodes to -> Enrolled Nodes

Optional: Remove manage nodes from Lighthouse 4

When you're ready to decommission Lighthouse 4, unenroll them by removing any Call Home and Lighthouse 4 Management tunnels:

• Login to the Lighthouse 5 CLI as a Lighthouse Administrator
• Run the commands:

sudo node-command --all config \\-d config.cms \\-d config.ssh \\-r sshforwards \\-r node
