Migrating and upgrading

You can upgrade to the 14.10 release of HCL Informix® or migrate from other database servers to Informix®. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix® database server can affect upgrading from a previous release.
