Yes, you can just move the WoW folder from C drive to D drive. Nothing else to worry about it except if you have a shortcut on your desktop, in that case you will need to change the shortcut to point to the new location, or just make a new shortcut.

The only issue I have ever had with moving a WOW installation to another directory is the patch did not want to take once. Not sure why it only happened the one time.
Ok cool thanks imma do that and change it to d drive shortcut. But since im not using the c drive one imma leave it there just for safe keeping. Just thought about it incase something happens i have it backed up.
Just in case, put the clean install(backup) in a folder or change the top level folder name so some odd program doesn't look it it instead of the folder on the SSD
