This section explains how to upgrade Terraform Enterprise to a new version. Learn more about availability during upgrades here.

Before Upgrade

We strongly recommend the following:

Create a backup copy of the storage prior to upgrading your instance. Backup and restore responsibility varies depending on your Terraform Enterprise operation mode.
Review the general Terraform Enterprise requirements, including credentials, hardware, operating system, data storage, and network.
Review the upgrade requirements and release notes for the specific Terraform Enterprise release.
Review the Upgrading TFE or Patching TFE Node Instances for your Terraform Enterprise active/active architecture.

From the installer dashboard (https://<TFE HOSTNAME>:8800/dashboard), click the "Check Now" button. Terraform recognizes the new version.
Click "View Update".
Review the release notes and then click "Install Update".

Connect to the Terraform Enterprise host machine using SSH.
Fetch the versions of Terraform Enterprise.
```
$ replicatedctl app-release ls --fetch
```
Upgrade to the latest version of Terraform Enterprise.
```
$ replicatedctl app-release apply
```
Alternatively, upgrade to a specific version of Terraform Enterprise.
```
$ replicatedctl app-release apply --sequence "504"
```

Determine the update path where the installer will look for new .airgap packages. You can do this from the console settings of your instance (https://<TFE HOSTNAME>:8800/console/settings) in the field Update Path.
Download the new .airgap package onto the instance and put it into the Update Path location.
From the installer dashboard (https://<TFE HOSTNAME>:8800/dashboard) click the "Check Now" button. Terraform recognizes the new version.
Click "View Update".
Review the release notes and then click "Install Update".

Print the AirgapPackagePath.

$ replicatedctl params export --template '{{.AirgapPackagePath}}'

On the Terraform Enterprise host machine, upload the desired airgap packages into the AirgapPackagePath.
Fetch the versions of Terraform Enterprise from the uploaded airgap packages.
```
$ replicatedctl app-release ls --fetch
```
List the available versions of airgap packages for the upgrade.
```
$ replicatedctl app-release ls
```
Upgrade to the latest version of the available airgap packages.
```
$ replicatedctl app-release apply
```
Alternatively, upgrade to a specific version, using one of the options listed in the output of the previous step.
```
$ replicatedctl app-release apply --sequence "504"
```
