Hi esmi thanks for the response.
I tried all your suggestions except from the last one to no avail, before I do the last one I’d like to understand the risks associated with it and what sort of data I may lose? I’m worried there may be plugin specific data outside of there e.g. I know W3 Total Cache stores information outside of the wp-content folder.
I have a lot of data in my current WordPress installation and I can’t afford to cause any sort of issues at this point in time.
