 ## Introduction
 
-Upgrades using Django migrations are not expected to work in AWX.  As a result, to upgrade to a new version, it is necessary to export resources from the old AWX node and import them into a freshly-installed node with the new version.  The recommended way to do this is to use the tower-cli send/receive feature.
+Early versions of AWX did not support seamless upgrades between major versions and required the use of a backup and restore tool to perform upgrades.
 
-This tool does __not__ support export/import of the following:
-* Logs/history
-* Credential passwords
-* LDAP/AWX config
+Users who wish to upgrade modern AWX installations should follow the instructions at:
 
-### Install & Configure Tower-CLI
-
-In terminal, pip install tower-cli (if you do not have pip already, install [here](https://pip.pypa.io/en/stable/installing/)):
-```
-$ pip install --upgrade ansible-tower-cli
-```
-
-The AWX host URL, user, and password must be set for the AWX instance to be exported:
-```
-$ tower-cli config host http://<old-awx-host.example.com>
-$ tower-cli config username <user>
-$ tower-cli config password <pass>
-```
-
-For more information on installing tower-cli look [here](http://tower-cli.readthedocs.io/en/latest/quickstart.html).
-
-
-### Export Resources
-
-Export all objects
-
-```$ tower-cli receive --all > assets.json```
-
-
-
-### Teardown Old AWX
-
-Clean up remnants of the old AWX install:
-
-```docker rm -f $(docker ps -aq)```     # remove all old awx containers
-
-```make clean-ui```              # clean up ui artifacts
-
-
-### Install New AWX version
-
-If you are installing AWX as a dev container, pull down the latest code or version you want from GitHub, build
-the image locally, then start the container
-
-```
-git pull                                        # retrieve latest AWX changes from repository
-make docker-compose-build                       # build AWX image
-make docker-compose                             # run container
-```
-For other install methods, refer to the [Install.md](https://github.com/ansible/awx/blob/devel/INSTALL.md). 
- 
-
-### Import Resources
-
-
-Configure tower-cli for your new AWX host as shown earlier.  Import from a JSON file named assets.json
-
-```
-$ tower-cli config host http://<new-awx-host.example.com>
-$ tower-cli config username <user>
-$ tower-cli config password <pass>
-$ tower-cli send assets.json
-```
-
---------------------------------------------------------------------------------
-
-## Additional Info
-
-If you have two running AWX hosts, it is possible to copy all assets from one instance to another
-
-```$ tower-cli receive --tower-host old-awx-host.example.com --all | tower-cli send --tower-host new-awx-host.example.com```
-
-
-
-#### More Granular Exports:
-
-Export all credentials
-
-```$ tower-cli receive --credential all > credentials.json```
-> Note: This exports the credentials with blank strings for passwords and secrets
-
-Export a credential named "My Credential"
-
-```$ tower-cli receive --credential "My Credential"```
-
-#### More Granular Imports:
-
-
-You could import anything except an organization defined in a JSON file named assets.json
-
-```$ tower-cli send --prevent organization assets.json```
