Documentation for upgrading from Elsa 1 to Elsa 2

[anupchaturvedi1]

Hi @sfmskywalker and team ,
I need your help as I am upgrading the Elsa 1 to Elsa 2.
I have gone through the "https://v2.elsaworkflows.io/docs/upgrading/1x-to-20#todo" which has some points when upgrading from Elsa 1 to Elsa 2.
But I have multiple other namespace and classes used which are not mentioned in the documentation.
Example of some missing namespace and class:
Elsa.Result
IWorkflowBuilder
IWorkflow
Variable
FaultWorkflowResult
WorkflowExecutionContext does not contains a definition of Workflow.
JavaScriptExpression
IActivityBuilder does not contains for ConditionExpression
Please let me know if there is any other documentation which I can refer.

Lacking any upgrade guidance going from v1 to v2, your best shot right now might be to learn about V2 and do some experiments, which will give you the necessary knowledge to adapt your V1 solution to V2.
