Prepare an older database for the current release

Current releases start from the database of 1.0.0-rc.1 and do not hold the 0.x migrations. Use this procedure when your database is older than 1.0.0-rc.1. The database prerequisites define the minimum upgrade history.

Before you start​

1.0 supports only the Helm chart. A Compose installation must first move to the chart:

  1. Upgrade the Compose installation to 0.95.0.
  2. Move that version to the chart, as Move from Compose to the Helm chart describes.
  3. Apply 0.95.1 and install its reconciler tooling.

Reach the baseline​

  1. Install 1.0.0-rc.1 with its signed image lock and its versioned upgrade instructions. These instructions own the stopped cutover to the database baseline.
  2. Run that release until its upgrade is complete.
  3. Upgrade to the target release, as its upgrade guide describes.

Check that it worked​

  1. Read the log of the migration Job of the target release. The migration completes. If the database has not reached 1.0.0-rc.1, the migration stops before it writes anything. Its message names the release to install.
