1. Modifying web address: 
   Considering an example,
   Existing link :
   https://wiki.solvay.com/display/SBSOTC/SBS+-+OtC+Home

   Required link:
   https://wiki.solvay.com/display/SBSOTC/SBS+-+CCT+home

   We just need to edit the name of the page.

2. Modifying key name:
   We should inform the user that for right now we cannot change the space key once it is done, what we can do is copy all the space to a new space giving a new space key.
