+
+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.
+
+Here's how to upgrade from Wheezy nodes running BigCouch to Jessie nodes using CouchDB:
+
+1. Follow [["migrating from BigCouch to plain CouchDB" => services/couchdb#migrating-from-bigcouch-to-plain-couchdb]], but only until the step where you removed BigCouch.
+2. Now upgrade to Jessie (see below)
+3. Continue with [["migrating from BigCouch to plain CouchDB" => services/couchdb#migrating-from-bigcouch-to-plain-couchdb]] at the point where you stopped for the first step, and deploy to the couchdb node.
+
+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.
