SPSS and AMOS 20: Considerations When Reopening Legacy Software Projects
Version 20 may be needed to reproduce an older project, but should not automatically be considered suitable for a new computer or study.
Preserve original data, syntax, and models; check the operating system, license, and modules; export results to durable formats before migrating to a current version (IBM, n.d.).
Install software from verifiable sources
- Official source
Verify the developer
- License
Choose an appropriate license
- Compatibility
Check operating system and version
- Verification
Open sample data and record the environment

A common need is reopening .sav data, .sps syntax, or an AMOS .amw model from an older study to reproduce its results. The objective is to preserve traceability rather than install an outdated environment at any cost.
For a new study, use a version licensed by the organization and still supported by its vendor. Running on one computer does not establish that the environment is safe, compatible, or reproducible elsewhere.
Do not disable security, use cracks, or download installers from sharing repositories. Use IBM’s portal, the IT department, or the organization’s licensed account.
2. Inventory the Project Before Opening It
| Component | Example | Purpose |
|---|---|---|
| Original data | .sav, .csv, codebook | Preserve variables and labels |
| Syntax | .sps and macros | Reproduce processing |
| Model | .amw and diagrams | Reproduce SEM |
| Output | .spv, tables/images/PDF | Cross-check results |
| Log | version, modules, plugins | Explain differences |
3. A Safe Migration Workflow
Create a read-only copy
Do not attempt conversion directly on the only copy.
Record the original environment
Save the SPSS/AMOS version, operating system, modules, and estimation options.
Open in a legally licensed environment
Prefer the organization’s archived computer or a newer version capable of reading the files.
Rerun using syntax
Compare descriptives, observation counts, missing data, and main results.
Export durable formats
Save CSV data with a codebook, text syntax, PDF/HTML tables, and model images.
4. Reproducibility Checklist
Example report
The original project was created using [SPSS/AMOS 20] on [environment]. Files were opened using [version] from the licensed source [ ]. Comparison of [N, descriptives, main coefficients] indicated [agreement/differences]; all differences were recorded in the migration log.
- Preserve original files unchanged.
- Retain a codebook and syntax.
- Record the version and operating system.
- Compare N, missing data, and main statistics.
- Record every warning when opening files.
- Save output in software-independent formats.
Conclusion
Legacy software’s value lies in reproducing the research record. A sound workflow prioritizes legally sourced installers, immutable copies, and cross-checks of results.
