Hello @MariaD,
it is possible to do a "backup" and bring it to SAS 9.4. There are two main paths to achieve this:
1. Use SMU (SAS Migration Utility) on SAS 9.2, it creates a package, which you can provide to SAS 9.4 installation (SDW) while you configure the new services. This will bring everything "as is" to 9.4.
2. Use partial promption. This is done with SAS Management Console, with the export Metadata and import Metadata fucntionality. The challenge is that in SAS 9.2 you cannot export the SAS security and server definition (users, groups, ACTs, custom roles, SASApp, database definitions, etc). So for this part, or either you do it manually and do the partial promotion afterwards (and re-asign security), or you use some other tools/tips. SAS Consultants often use SMU to a Lev9 (temporary level) to bring only the metadata and partial promotion of the security objects from 9.4 Lev9 to SAS 9.4 Lev2 (your final config).
