Upgrade infrastucture with integration points

A system comprising:

• one or more processors;
• and
• a memory comprising code stored thereon that, when executed by at least a first of the one or more processors, performs a method comprising:
• defining a plurality of integration points, wherein each of the plurality of integration points is associated with one of a plurality of workflow processing points included in an upgrade workflow;
• receiving a plurality of command lists, wherein each of the plurality of command lists includes one or more commands and is associated with one of the plurality of integration points;
• associating each command included in one of the plurality of command lists with one of a plurality of code entities;
• and
• performing a first processing that performs the upgrade workflow to upgrade a system, wherein the first processing further includes:
• executing a first executable code corresponding to the plurality of workflow processing points, wherein a first workflow processing point of the plurality of workflow processing points is associated with a first integration point of the plurality of integration points;
• and
• in response to said executing reaching the first workflow processing point corresponding to the first integration point, performing a second processing including:
• executing one or more commands of a first command list of the plurality of command lists, wherein the first command list is associated with the first integration point;
• and
• for each of the one or more commands of the first command list that is executed, invoking a corresponding one of the plurality of code entities associated with said each command of the first command list, wherein said corresponding one code entity performs first customized processing in connection with upgrading a first feature, facility or service in the system.

A non-transitory computer readable medium comprising code stored thereon that, when executed by a processor, performs a method comprising:

• defining a plurality of integration points, wherein each of the plurality of integration points is associated with one of a plurality of workflow processing points included in an upgrade workflow;
• receiving a plurality of command lists, wherein each of the plurality of command lists includes one or more commands and is associated with one of the plurality of integration points;
• associating each command included in one of the plurality of command lists with one of a plurality of code entities;
• and
• performing a first processing that performs the upgrade workflow to upgrade a system, wherein the first processing further includes:
• executing a first executable code corresponding to the plurality of workflow processing points, wherein a first workflow processing point of the plurality of workflow processing points is associated with a first integration point of the plurality of integration points;
• and
• in response to said executing reaching the first workflow processing point corresponding to the first integration point, performing a second processing including:
• executing one or more commands of a first command list of the plurality of command lists, wherein the first command list is associated with the first integration point;
• and
• for each of the one or more commands of the first command list that is executed, invoking a corresponding one of the plurality of code entities associated with said each command of the first command list, wherein said corresponding one code entity performs first customized processing in connection with upgrading a first feature, facility or service in the system.
