+
+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 0.8.0
+
+### Step 2: Prepare to migrate from BigCouch to CouchDB
+
+<%= render :partial => 'docs/platform/common/bigcouch_migration_begin.md' %>
+
+### Step 3: 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.**
+
+For each one of your nodes, login to it and do the following process:
+
+ # 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-confold dist-upgrade
+
+ # if either of these return anything, you will need to resolve them 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
+
+ # clean out old package files
+ apt-get clean
+
+ # test to see if you have enough space to upgrade, the following will alert
+ # you if you do not have enough space, it will not do the actual upgrade
+ apt-get -o APT::Get::Trivial-Only=true dist-upgrade
+
+ # do first stage upgrade
+ apt-get -y -o DPkg::Options::=--force-confold upgrade
+
+ # repeat the following until it makes no more changes:
+ apt-get -y -o DPkg::Options::=--force-confold dist-upgrade
+
+ # resolve any apt issues if there are some
+ apt-get -y -o DPkg::Options::=--force-confold -f install
+
+ # clean up extra packages
+ apt-get autoremove --yes
+
+ reboot
+
+
+Potential Jessie Upgrade Issues
+-------------------------------
+
+**W: Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-max**
+
+You can ignore these warnings, they will be resolved on upgrade.
+
+**E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?**
+
+If you get this error, run `apt-get update` and then re-run the command.
+
+**Unmet dependencies. Try using -f.**
+
+Sometimes you might get an error similar to this (although the package names may be different):
+
+ You might want to run 'apt-get -f install' to correct these.
+ The following packages have unmet dependencies:
+ lsof : Depends: libperl4-corelibs-perl but it is not installed or
+ perl (< 5.12.3-7) but 5.20.2-3+deb8u4 is installed
+
+If this happens, run `apt-get -f install` to resolve it, and then re-do the previous upgrade command
+you did when this happened.
+
+**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.
+
+### Step 4: Deploy LEAP Platform 0.8 to the Couch node
+
+You will need to deploy the 0.8 version of LEAP Platform to the couch node before continuing.
+
+1. deploy to the couch node:
+
+ ```
+ workstation$ leap deploy <couchdb-node>
+ ```
+
+ If you used the iptables method of blocking access to couchdb, you need to run it again because the deploy just overwrote all the iptables rules:
+
+ ```
+ server# iptables -A INPUT -p tcp --dport 5984 --jump REJECT
+ ```
+
+### Step 5: Import Data into CouchDB
+
+<%= render :partial => 'docs/platform/common/bigcouch_migration_end.md' %>
+
+### Step 6: Deploy everything
+
+Now that you've upgraded all nodes to Jessie, and migrated to CouchDB, you are ready to deploy LEAP Platform 0.8 to the rest of the nodes:
+
+ workstation$ cd <provider directory>
+ workstation$ leap deploy
+
+### Step 7: Test and cleanup
