Issue
Sigma data files from one computer are being opened on another computer with a different Sigma version, potentially causing system instability or data corruption.
Product Line
Satchwell BAS & Sigma
Environment
Satchwell Sigma
Cause
Sigma data files are version-dependent. When a specific Sigma version is installed, only data files created or used with that same version should be accessed. Copying the entire Sigma folder from one version to another may appear to work but can introduce hidden issues due to background tasks and version mismatches.
Resolution
- Do not copy the entire Sigma folder from one version to another system.
- Avoid restoring files that were accessed on a different Sigma version back onto the customer’s machine.
- Use virtual machines to host different Sigma versions if multiple versions are needed for support or testing.
- Refer to the article “How to Identify the Sigma Version Installed on a Computer” for guidance on matching release and build numbers.
