Upgrading

How to upgrade the Anka Build Virtualization CLI

We follow semantic versioning; minor and major version increases can have significant changes.

Upgrade Procedure (without Anka Build Cloud Controller & Registry)

Install the new anka pkg. Follow the install instructions
Upgrade the guest addons inside the VM templates with anka start -u. Check the upgrade notes to see if this step is necessary.

When upgrading the entire Anka Build infrastructure (Controller/Registry and Nodes), execute the steps in the following sequence:

Run sudo ankacluster disjoin on your nodes
Install the new anka pkg. Follow the install instructions
Upgrade the guest addons inside the VM templates with anka start -u
Push the newly upgraded VM templates to registry with anka registry push {template} --tag <tag>
Go to the Controller & Registry and upgrade to the latest version.
On the nodes, run sudo ankacluster join http://{controller address}

Existing Version	Target Version	Recommendation
1.4.3	2.x.x	Requires upgrade of all existing VM templates with `anka start -u` and push to the registry
2.x	2.1.2	Only requires upgrade of existing Catalina VM templates with `anka start -u` and push to the registry
