I need to run a simple fix in my Drupal 7 website. The website administrator, not being a Drupal specialist, installed the SMTP module in the root /modules folder, instead of the /sites/all/modules folder. Now I need to upgrade the SMTP module and noticed the mistake. My first impulse was to move the SMTP folder from /modules into /sites/all/modules, and then proceed with the regular upgrade.
My question is: do you think that moving the SMTP folder from root /modules into /sites/all/modules could cause any problems, like data loss or website crash?
