Katalyst: New experiments cannot be created after database migration to cloud

Description

• After migrating Katalyst to a new server infrastructure, users can access the application and retrieve existing experiments but cannot save or create new experiments.
• Existing (pre‑migration) experiments can be imported or opened without issues.
• The problem appears only for experiments created after the migration.

Solution

• Verify that all backend services and databases used by Katalyst are correctly migrated and reachable from the new application server:
  • Spectrus DB / experiment database connection strings.
  • File storage locations for experiment data, templates, and attachments.
• Common causes and checks:
  • Permissions – the new Katalyst server’s service account may not have write access to the shared storage or database.
  • Configuration files – hostnames/paths may still point to old servers or locations.
  • DNS changes – ensure DNS updates for Katalyst URLs are complete and consistent.
• Review application logs when a user attempts to create a new experiment:
  • Look for errors related to DB inserts, file creation, or transaction failures.
• Once configuration and permissions are corrected:
  • Test creation of a new experiment with a standard workflow.
  • Confirm that saving, reopening, and subsequent processing all work as expected.
