Steps for In-Place Upgrade

Prerequisites

1

Have HQ deployed

The first step is to have HQ deployed and agent_key being obtained upon environment creation

2

Prepare Lenses 5 Configuration Files

Before doing upgrade, make a copy of all configuration files.

In case of Helm deployment that would be:

• values.yaml

In case of Archive of Docker deployment that would be:

• lenses.conf It is strongly suggested to rename this file to lenses-agent.conf for the upgrade.

• provisioning.yaml

In case you are missing provisioning.yaml configuration file, re-creating it will be covered in next step.

3

Convert all connections / alerts / channels to Provisioning

There were multiple ways how Lenses resources could have been managed in the past:

1. Wizard

2. Provisioning v1

3. Provisioning v2

For Lenses (6) Agent, it is recommended that all connections (kafka, schema-registry, connect,...) are kept inside of provisioning.yaml file in version 2. Provisioning

Differences of provisioning between version 1 and 2 can be seen below:

Steps to deploy Agent

1

Follow prerequisite steps above

Steps:

• Deploy Lenses HQ

• Prepare Lenses 5 Configuration Files

• Prepare Provision file

Once you went through the steps above you'll be ready to move ahead and deploying Agent at the side.

2

Clone / Migrate Lenses 5 Groups

In this step you'll ensure that Groups (with permissions) that exist in Lenses 5 will still have the same amount of permissions in Lenses 6 for newly created Environment (Agent).

Migration of :

• data policies

• alerts

• sql processors

is not necessary in case Agent will re-use the same database as Lenses 5.

To execute this step we have tooling that can help you Lenses Migration Tool.

Be aware, cloning of alerts is not available yet via script above.

Once script is initiated you should be able to see new:

• Groups and

• Roles with its permissions inside HQ screen.

These are matching the ones you have in Lenses 5 instance and will enable users to see new Environment once it is connected 👇

3

Stop Lenses 5 instance and start Lenses 6 Agent

There are multiple deployment methods for the Agent deployment, please choose one from Installation

Two Lenses instances shouldn't be connecting to the same database therefore old Lenses 5 should be stopped.

Note that there is no rollback mechanism once upgrade is initiated over the same database.

4

Check Environment screen for a new Agent

Screen of "Connected" Agent should look as follows and should be seen by AD groups that has been cloned in step 3️.
