h1. OS Upgrade 

 This is a list of steps as guidelines for OS upgrades. 

 * create a temporary _group_vars/<new-suite>/system.yml_ in a git branch: 

 <pre> 
 --- 
 system: 
   distribution: 
     debian: 
       codename: bullseye 
     dc: 
       codename: bullseye 

 </pre> 

 * (I often choose Elwing first) ansible-playbook --diff -l Elwing -t apt playbooks/common.yml | tee /tmp/dc.log 
 * apt upgrade 
 * apt dist-upgrade (check if removed packages are problematic) 
 ** accept new version of /etc/services and copy-paste content of _local services_ from _/etc/services.dpkg-old_ to avoid having to redeploy all services 
 ** do not accept new versions for: 
 *** /etc/smartd.conf 
 *** /etc/snmp/snmp.conf 
 *** /etc/oidentd.conf 
 *** /etc/sudoers 
 *** /etc/rsyslog.conf 
 *** /etc/apt-cacher-ng/acng.conf 
 *** /etc/zabbix/* 
 *** /etc/logrotate.d/* 
 ** check the diff manually for other files 
 * if PHP FPM: (to avoid having to redeploy all vhosts) (example for PHP 7.3->7.4) 
 ** rm /etc/php/7.4/fpm/pool.d/www.conf 
 ** cp /etc/php/7.3/fpm/pool.d/* /etc/php/7.4/fpm/pool.d/ 
 ** sed -i 's/7\.3/7.4/g' /etc/php/7.4/fpm/pool.d/* 
 ** systemctl restart php7.4-fpm.service 
 ** run the _playbooks/common.yml_ playbook 
 ** run common web playbook _playbooks/tenants/duckcorp/web.yml_ with _-t web-common_
