====== Puppet Upgrade 4.x to 5.x ======
This is simple steps to upgrade puppet.

==== Stop service ====
<code bash>
systemctl stop puppetserver
systemctl stop puppetdb
</code>

==== Update Puppet server ====
Download New repo [[http://yum.puppetlabs.com/puppet/el/7/x86_64/puppet-release-1.0.0-1.el7.noarch.rpm|puppet-release]]

<code bash>
yum install puppetserver
</code>

==== Postgresql upgrade ====

Install New postgres [[https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7Workstation-x86_64/pgdg-redhat96-9.6-3.noarch.rpm|pgdg-redhat9.6]]

<code bash>
systemctl stop postgresql-9.5
yum install postgresql96-server
yum install postgresql96-contrib
</code>

==== Upgrade Postgresql data ====

:!: Do it as user `postgres`

<code bash>
/usr/pgsql-9.6/bin/initdb /var/lib/pgsql/9.6/data/
/usr/pgsql-9.6/bin/pg_upgrade -b /usr/pgsql-9.5/bin/ -B /usr/pgsql-9.6/bin/ -d /var/lib/pgsql/9.5/data/ -D /var/lib/pgsql/9.6/data/ -v

systemctl start postgresql-9.6
</code>

==== Upgrading puppetdb ====
Upgrade puppetdb
<code bash>
yum install puppetdb
yum install puppetdb-termini

puppet resource service puppetdb ensure=stopped
puppet resource package puppetdb ensure=latest
puppet resource service puppetdb ensure=running
</code>


==== Final steps after your puppet started working ====
Optimize postgresql puppetdb.\\
:!: run as `postgres` user.

<code bash>
./analyze_new_cluster.sh
./delete_old_cluster.sh
</code>


==== If it doesn't works as expected with puppetdb ====
 :!: Run as `postgres` user

 :?: Only if you do not care for the data

<code psql>
drop database 'puppetdb'
</code>

<code bash>
createdb -E UTF8 -O puppetdb puppetdb
psql puppetdb -c 'create extension pg_trgm'
</code>
