An airgapped installation of Terraform Enterprise is an environment where the instance has no access to the internet. This is often done for security reasons to prevent unauthorized access and tighter control.
What additional considerations need to be taken into account when planning an airgapped Terraform Enterprise upgrade vs an online upgrade?
When upgrading an airgrapped installation, the package needs to be downloaded and then transferred onto the airgapped machine. The upgrade package will contain all needed versions to get from the version that is currently on the instance to the newest version. It is recommended to upgrade the airgapped installation as often as possible, long gaps between upgrades can lead to longer and more complicated upgrade experiences.
