SIMCA and SIMCA-online compatibility issues (Q904)
This article gives an overview of the compatibility issues present in SIMCA 15 and SIMCA-online 15.
File format: A project created in SIMCA 15.0.1 or SIMCA-online 15.0.1 cannot be used for predictions in SIMCA 15.0.0 nor SIMCA-online 15.0.0.
Dynamic lags: There may be small differences in the results from models using dynamic lags between SIMCA 15.0.0/15.0.1 and SIMCA-online 15.0.1 (first version with dynamic lags).

Dynamic lags: Use SIMCA 15.0.2 in combination with SIMCA-online 15.0.1 or later for models with dynamic lags.
Batch models: Use SIMCA 15.0.2 in combination with any SIMCA-online 15 version and especially if the projects include batch level models.
File format: The usp-file format was broken between SIMCA 15.0.0 and 15.0.1. This means that:
- Projects created in SIMCA 15.0.1 are compatible with SIMCA-online 15.0.1 but not with SIMCA 15.0.0 nor SIMCA-online 15.0.0. That is also the case for projects created in SIMCA-online 15.0.1.
- Projects created in SIMCA 15.0.2 are compatible with all SIMCA-online 15-versions.
Dynamic lags: The calculations behind the handling of dynamic lags were improved after the release of SIMCA 15.0.0 and SIMCA-online 15.0.0.
