Katalyst: Error when opening experiments created in much older versions

Description

• Experiments created many versions ago (major upgrades since then) sometimes:
  • Fail to open, or
  • Open with missing components (plates, analyses).
• Newer experiments open without problems.

Solution

• Verify version compatibility:
  • Check how far back the current version officially supports experiment formats from older releases.
• Migration strategy:
  • If possible, open the experiment first in an intermediate version that is closer to its original version, then re‑save and upgrade stepwise.
  • Alternatively, export the experiment from the old environment and import into the new environment using supported paths.
• If direct opening is required:
  • Review logs for migration/conversion errors when opening the experiment.
  • Work with Technical Support and Services team to identify whether a schema conversion script or patch is needed.
• Long term:
  • Encourage periodic migration of important legacy experiments as part of upgrade projects, rather than leaving them many major versions behind.
