Upgrading Debian 8 Jessie to Debian 9 Stretch

If configuration files are changed the old version will usually be copied to a backup file (*.dpkg-old). Nevertheless it is a good idea to make a system backup yourself before upgrading.

Description how to upgrade

  • https://www.cyberciti.biz/faq/how-to-upgrade-debian-8-jessie-to-debian-9-stretch/

Network

  • Device names stay the same (eth0, ...). Debian 9 only uses a new naming scheme for new installations.

Bacula 7.4.4

  • So far I had no problems to connect bacula-fd v7.4.4 to a bacula server v7.0.5

FreeRadius 3.0.12

  • Major upgrade from version 2. The configuration will not be automatically merged. You have to do this manually.
  • Basic configuration stays pretty much the same. Some configuration variables have been renamed or moved to a different position.
  • New configuration directories:
    /etc/freeradius/3.0
    /etc/freeradius/3.0/mods-available
    /etc/freeradius/3.0/mods-enabled
    /etc/freeradius/3.0/sites-available
    /etc/freeradius/3.0/sites-enabled
