Migration of configuration data from one software installation through an upgrade

A device for migrating current setting parameter values through a software upgrade, the device comprising:

• a. means for storing current setting parameter values and a current version number parameter value of a current software version in a non-volatile memory;
• b. means for loading a new software version into a system memory, wherein the new software version includes a new version number parameter value, new setting parameters, and default new setting parameter values;
• and
• c. means for controlling for storing in the non-volatile memory for each of the new setting parameters, the current setting parameter value, if available, and for each of the new setting parameters for which a current setting parameter value is not available, storing a corresponding default new setting parameter value in the non-volatile memory.

A device including a software version, the device comprising:

• a. a system memory to store a current software version, wherein the current software version includes one or more adjustable current setting parameters, current setting parameter values, a version number parameter, and a current version number parameter value;
• b. a non-volatile memory including the current version number parameter value and the current setting parameter values loaded in the system memory;
• and
• c. a controller to overwrite the current software version in the system memory with a new software version, wherein the new software version includes one or more adjustable new setting parameters, default values for the new setting parameters, the version number parameter, and a new version number parameter value, and to store in the non-volatile memory for each of the new setting parameters, the current setting parameter value, if available, and for each of the new setting parameters for which a current setting parameter value is not available, storing a corresponding default new setting parameter value in the non-volatile memory.

A method of migrating current setting parameter values through a software upgrade, the method comprising:

• a. storing current setting parameter values and a current version number parameter value of a current software version in a non-volatile memory;
• b. loading a new software version into a system memory, wherein the new software version includes a new version number parameter value, new setting parameters, and default new setting parameter values;
• c. for each of the new setting parameters, storing in a temporary memory, the current setting parameter value, if available;
• d. for each of the new setting parameters for which a current setting parameter value is not available, storing a corresponding default new setting parameter value in the temporary memory;
• and
• e. storing the current setting parameter values and the default new setting parameter values from the temporary memory in the non-volatile memory.

A device to migrate current setting parameter values through a software upgrade, the device comprising:

• a. a non-volatile memory to store current setting parameter values and a current version number parameter value of a current software version;
• b. an upgrade interface to load a new software version into a system memory, wherein the new software version includes a new version number parameter value, new setting parameters and default new setting parameter values;
• and
• c. a control circuit to store in the non-volatile memory for each of the new setting parameters, the current setting parameter value, if available, and for each of the new setting parameters for which a current setting parameter value is not available, to store a corresponding default new setting parameter value in the non-volatile memory.
