Important Notes

These instructions are ONLY for commercial customers with current Annual Support.

If you also own one or more optional plug-in Solver Engines (such as Gurobi, LSSQP, etc.), upgrade your Solver SDK Platform first and then upgrade any optional plug-in Solver Engine(s). Your Frontline Solver Platform and plug-in Solver Engines must be the same version number to work together.
