# Migrating juju to HP Cloud’s Horizon

Share the article

HP Cloud retired its old regions this month. If you use [juju](https://juju.ubuntu.com/) on HP Cloud and your account was created before this year, you may need to update your [juju config](https://juju.ubuntu.com/docs/config-hpcloud.html) and possibly complete your project setup in [Horizon](https://horizon.hpcloud.com/).

There are two changes you must make to each HP Cloud environment listed in `environments.yaml`. Set the `region` option to “region-a.geo-1″ or “region-b.geo-1″, which are US West and US East respectively. The new regions do not automatically assign public IPs. The `use-floating-ip` option must be set to “true” to tell juju to request a public address.

```
use-floating-ip: true
region: region-a.geo-1
```

Note that juju does not yet release the public address when you destroy the machine, You need to use the nova command line tools or the `Horizon console > Project > Compute > Access & Security > Floating IPs` to release them. We will release a fix for “[Floating IPs are not recycled in OpenStack Havana](https://bugs.launchpad.net/juju-core/+bug/1247500)” soon.

If you haven’t used these regions before, you needs to register your public SSH keys and create a default network for each one you use. Visit `Horizon console > Project > Compute > Access & Security > Key Pairs`. Most people migrating just copied their public keys to the new region. Visit `Horizon console > Project > Networks > Network` and verify or create a default network, something like 10.0.0.0/24.
