Migrating and Upgrading Projects

Supabase ships fast and we endeavor to add all new features to existing projects wherever possible. In some cases, access to new features require upgrading or migrating your Supabase project.

Upgrade your project#

When you pause and restore a project, the restored database includes the latest features. This method does include downtime, so be aware that your project will be inaccessible for a short period of time.

1. On the General Settings page in the Dashboard, click Pause project. You will be redirected to the home screen as your project is pausing. This process can take several minutes.
2. After your project is paused, click Restore project. The restoration can take several minutes depending on how much data your database has. You will receive an email once the restoration is complete.

Migrate your project#

Migrating projects can be achieved using the Supabase CLI. This is particularly useful for older projects (e.g. to use a newer Postgres version).

Before you begin#

• Install Postgres so you can run psql and pg_dump.
• Install Supabase CLI.
• Create a new Supabase project.
• Store the old project's database URL as $OLD_DB_URL and the new project's as $NEW_DB_URL.

Backup your old database#

1. Run the following command from your terminal:

1supabase db dump --db-url "$OLD_DB_URL" -f roles.sql --role-only
2supabase db dump --db-url "$OLD_DB_URL" -f schema.sql
3supabase db dump --db-url "$OLD_DB_URL" -f data.sql --data-only

Restore to your new project#

In your new project:

1. Enable Database Webhooks if you enabled them in your old project.
2. Enable any extensions that were enabled in your old project.
3. Create any custom roles that were created in your old project.

Then run the following command from your terminal:

1psql \
2  --single-transaction \
3  --variable ON_ERROR_STOP=1 \
4  --file schema.sql \
5  --file data.sql \
6  --dbname "$NEW_DB_URL"

Enable publication on tables#

Replication for Realtime is disabled for all tables in your new project. On the Replication page in the Dashboard, select your new project and enable replication for tables that were enabled in your old project.

Migrate Storage objects#

The new project has the old project's Storage buckets, but the Storage objects need to be migrated manually. Use this script to move storage objects from one project to another.

// npm install @supabase/supabase-js@1
const { createClient } = require('@supabase/supabase-js')

const OLD_PROJECT_URL = 'https://xxx.supabase.co'
const OLD_PROJECT_SERVICE_KEY = 'old-project-service-key-xxx'

const NEW_PROJECT_URL = 'https://yyy.supabase.co'
const NEW_PROJECT_SERVICE_KEY = 'new-project-service-key-yyy'

;(async () => {
  const oldSupabaseRestClient = createClient(OLD_PROJECT_URL, OLD_PROJECT_SERVICE_KEY, {
    schema: 'storage',
  })
  const oldSupabaseClient = createClient(OLD_PROJECT_URL, OLD_PROJECT_SERVICE_KEY)
  const newSupabaseClient = createClient(NEW_PROJECT_URL, NEW_PROJECT_SERVICE_KEY)

  // make sure you update max_rows in postgrest settings if you have a lot of objects
  // or paginate here
  const { data: oldObjects, error } = await oldSupabaseRestClient.from('objects').select()
  if (error) {
    console.log('error getting objects from old bucket')
    throw error
  }

  for (const objectData of oldObjects) {
    console.log(`moving ${objectData.id}`)
    try {
      const { data, error: downloadObjectError } = await oldSupabaseClient.storage
        .from(objectData.bucket_id)
        .download(objectData.name)
      if (downloadObjectError) {
        throw downloadObjectError
      }

      const { _, error: uploadObjectError } = await newSupabaseClient.storage
        .from(objectData.bucket_id)
        .upload(objectData.name, data, {
          upsert: true,
          contentType: objectData.metadata.mimetype,
          cacheControl: objectData.metadata.cacheControl,
        })
      if (uploadObjectError) {
        throw uploadObjectError
      }
    } catch (err) {
      console.log('error moving ', objectData)
      console.log(err)
    }
  }
})()
