Chapter 4. Migrating within a maintenance window

Prerequisites

Perform a dry run migration in a staging environment to estimate the timing of the data export and import phases accurately. Once you are satisfied with the results, proceed with the production migration.

  2. Export data from Apicurio Registry 2.6 using the export script. See Migration scripts reference.
  3. Shut down Apicurio Registry 2.6.
  4. Deploy Apicurio Registry 3.x with updated configuration. See Updating registry configuration.
  5. Import data into Apicurio Registry 3.x using the import script. See Migration scripts reference.
  6. Validate the import using the verification scripts. See Migration scripts reference.
  7. Update client application configurations to point to Apicurio Registry 3.x. See Migrating Apicurio Registry client applications.
