I am in the process of upgrading Open Source Puppet from Server version 3.8.7 (which is hosted on Ubuntu 14.04 ) to a New version of Puppet on Ubuntu 16.04.
i have listed all the existing modules in current version however deciding which Open Source version to be chosen for upgrade is not very clear from documentations.
Hence,request help on how to choose Next version of puppet server on Ubuntu 16.04? Can we upgrade straight from 3.x to 5.x or 6.x?
Anyone who has done this kind of upgrade, please share your learnings which can support us to complete the safe upgrade.
