Is there a specific evaluation for ACS 4.2.1 (I have found 4.2.0 from this thread) but 4.2.1 would be a better option as we need to migrate to the latest 4.2.1 in production after the evaluation period.
Is it possible to install ACS 4.2 full version over an evaluation version of ACS 4.2? It it just a case of electing to keep the existing database when installing the full version of software?
