Ensure that the operating system is at the proper version and level to run Adaptive Server 12.5. Be sure that you have installed the most recent operating system patches to ensure that you have the latest bug fixes.
For release 12.5 operating system requirements, see the installation guide for your platform. See the ASE Migration Resources Web page for updates about recommended Sybase EBFs (bug fixes).
If you need to perform an operating system upgrade, do so before migrating. Test the new system to be sure it’s working properly to avoid introducing unrelated errors into the migration process.
