LEAP Platform release 0.8 introduces several major changes that need do get taken into account while upgrading:

* Dropping Debian Wheezy support. You need to upgrade your nodes to jessie before deploying a platform upgrade.
* Dropping BigCouch support. LEAP Platform now requires CouchDB and therefore you need to migrate all your data from BigCouch to CouchDB.

Upgrading to Platform 0.8
---------------------------------------------

### Step 1: Get new leap_platform and leap_cli

    workstation$ gem install leap_cli --version 1.8
    workstation$ cd leap_platform
    workstation$ git pull
    workstation$ git checkout 0.8

### Step 2: Upgrade to Jessie

#### For couchdb nodes running BigCouch

For nodes running BigCouch, you must migrate the data to CouchDB:

1. Export BigCouch Data<br>
Follow [["migrating from BigCouch to plain CouchDB" => services/couchdb#migrating-from-bigcouch-to-plain-couchdb]], but only until the step where you remove BigCouch.

1. Upgrade to Jessie<br>
See below for detailed example of upgrading from Wheezy to Jessie.

1. Import Data to CouchDB<br>
Continue with [["migrating from BigCouch to plain CouchDB" => services/couchdb#migrating-from-bigcouch-to-plain-couchdb]] at the point where you stopped (right after removing BigCouch).

#### For all other nodes

See below for how to upgrade to Debian Jessie.

## Step 3: Deploy everything

When you have upgraded all nodes to Jessie, you are ready to deploy:

    workstation$ cd <provider directory>
    workstation$ leap deploy
    workstation$ leap test

Upgrade from Debian Wheezy to Jessie
------------------------------------------------

There are the [Debian release notes on how to upgrade from wheezy to jessie](https://www.debian.org/releases/stable/amd64/release-notes/ch-upgrading.html). Here are the steps that worked for us, but please keep in mind that there is no bullet-proof method that will work in every situation. USE AT YOUR OWN RISK.

    # keep a log of the progress:
    screen
    script -t 2>~/leap_upgrade-jessiestep.time -a ~/upgrade-jessiestep.script

    # ensure you have a good wheezy install:
    export DEBIAN_FRONTEND=noninteractive
    apt-get autoremove --yes
    apt-get update
    apt-get -y -o DPkg::Options::=--force-confnew dist-upgrade

    # if anything is held, you need to resolve it before continuing:
    dpkg --audit
    dpkg --get-selections | grep 'hold$'

    # switch sources to jessie
    sed -i 's/wheezy/jessie/g' /etc/apt/sources.list
    rm /etc/apt/sources.list.d/*
    echo "deb http://deb.leap.se/0.8 jessie main" > /etc/apt/sources.list.d/leap.list

    # remove pinnings to wheezy
    rm /etc/apt/preferences
    rm /etc/apt/preferences.d/*

    # get jessie package lists
    apt-get update

    # test if there is enough disk space for the upgrade
    apt-get clean
    apt-get -o APT::Get::Trivial-Only=true dist-upgrade

    # do first stage upgrade
    apt-get -y -o DPkg::Options::=--force-confnew upgrade

    # repeat dist-upgrade until it makes no more changes:
    apt-get -y -o DPkg::Options::=--force-confnew dist-upgrade

    # resolve any apt issues if there are some
    apt-get -f install

    # clean up extra packages
    apt-get autoremove --yes

    reboot


### Issues

**Failure restarting some services for OpenSSL upgrade**

If you get this warning:

    The following services could not be restarted for the OpenSSL library upgrade:
      postfix
    You will need to start these manually by running '/etc/init.d/<service> start'.

Just ignore it, it should be fixed on reboot/deploy.
