Is it easily possible reaming he Elgg install folder name... then changing these setting accordingly:

changing The site URL:

The full path of the Elgg installation:

The full path of the data directory:

...or is even attempting such concepts a total nightmare waiting to happen?

Renaming my Elgg install folder is on my list, yet can also just do new instal at this stage....

May as well ask before attempting something that could be fatalistic waste of time.
