the next task is to bring this project up to the current family say Cyclone II, so that I can use the newer version of Quartus.
Do you foresee to redo the project with new device or is there any way out?

Usually a project targets a specific board. If your board has a Cyclone I device, then you need to use a version of Quartus that supports Cyclone I. I'm not sure when they dropped support for Cyclone I in the web edition, but its most likely the last 10.x version.
If your design is really just to learn VHDL and it doesn't really target any hardware, then you can just create a new project, import the VHDL and .SDC (timing constraints) file and synthesize for a Cyclone IV.
