@title = 'Upgrade to 0.8'
@toc = false
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:
apt-get autoremove
apt-get update
DEBIAN_FRONTEND=noninteractive apt-get -y -o DPkg::Options::=--force-confold 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
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
DEBIAN_FRONTEND=noninteractive apt-get -y -o DPkg::Options::=--force-confold upgrade
# repeat dist-upgrade until it makes no more changes:
DEBIAN_FRONTEND=noninteractive apt-get -y -o DPkg::Options::=--force-confold dist-upgrade
# resolve any apt issues if there are some
apt-get -f install
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.
