EdgeDB v2 (Sagittarius)​

Upgrading​

Local instances

To upgrade a local project, run the following command inside the project directory.

$ 

edgedb project upgrade --to-latest

Alternatively, specify an instance name if you aren’t using a project.

$ 

edgedb project upgrade --to-latest -I my_instance

Hosted instances

To upgrade a remote (hosted) instance, we recommend the following dump-and-restore process.

1. Spin up an empty 2.0 instance by following one of our deployment guides. These guides have been updated to 2.0. Keep the DSN of the newly created instance handy.

1. Take your application offline, then dump your v1.x database with the CLI

   Copy

   $ 

   edgedb dump --dsn <old dsn> --all my_database.dump/

   This will dump the schema and contents of your current database to a file on your local disk called my_database.dump. The file name isn’t important.

2. Restore the empty v2.x instance from the dump

   Copy

   $ 

   edgedb restore --all my_database.dump/ --dsn <new dsn>

   Once the restore is complete, update your application to connect to the new instance.

This process will involve some downtime, specifically during steps 2 and 3. We are working on an in-place upgrade workflow that will reduce the amount of downtime involved and avoid the need to spin up a new instance. We’ll publish that soon; join the Discord for updates. Though for most applications the dump-and-restore workflow will be simpler and less error-prone.

New features​

Integrated admin UI​

All v2 instances ship with a built-in rich admin GUI. Access it by running edgedb ui inside any EdgeDB project, or specify a local instance name with edgedb ui -I my_inst. The command opens the instance’s admin UI using the default system browser.

The current iteration of the GUI has

• a data browser and editor

• a REPL for writing and executing EdgeQL queries

• a schema introspection tool with text-based and graphical visualizations of the instance’s current schema
