Conversion from NATURAL 217 to NATURAL 22x

So... you want to convert from NAT217 to NAT22x... please follow these steps for a smooth conversion.

Before you begin your conversion, review the NAT22 Planning Guide (manual NAT-220-005), the NAT222, 223, 224, 225, 226, 227 and 228 Release Notes, and the Supplemental Release Notes (US) (manual NAT-224-009). These documents contain important information on NATURAL features, documentation corrections/changes, and early-warnings (when applicable).

Information in the Release Notes is NOT duplicated from one SM-level to the next, so it is recommended that these notes be considered as a single document, readily accessable to those installing and maintaining NATURAL.

  4. If you have user-supplied error messages, migrate these error messages via SYSMAIN, or with the SYSERR unload and load facilities ERRULDUS and ERRLODUS.
  5. Continue with your NATURAL Installation per the Operations Manual.
