I have CEP project built in Apama 4 and I am now migrating to Apama 5.1. But I am new to it and unable to figure out how to open even the old project. I went through the pdfs but not much help. Please someone guide me as to how to begin.
I think you are asking how to do this within your Eclipse environment (Apama studio)
Go to File -> Import -> Existing Projects into Workspace [Click next]
Select the root directory of the project, you will see the project name populating in the window below.
Click Finish
