Upgrading to a Server With Larger Page Sizes

SAP ASE earlier than version 12.5 used 2K logical page sizes. You cannot change an installation’s page size by upgrading. That is, if your current SAP ASE uses 2K logical pages, you can upgrade only to an SAP ASE server that uses 2K logical pages.

However, you can migrate databases with 2K logical pages from earlier versions of SAP ASE.
