This happens quite often.

When you install a new version of the installed software / cms it makes sense to create a subdomain maybe new.domain.com pointing to the new version directory.

After everything is checked the original path domain.com should be changed to the new version of a software.

Existing:
/var/www/domain.com/cms_v1 = domain.com

Now installing:
/var/www/domain.com/cms_v2 = new.domain.com

Checking CMS and everything is well:

Change existing:
/var/www/domain.com/cms_v1 to /var/www/domain.com/cms_v2 = domain.com

deleting testing domain:
new.domain.com (path should not be removed - only as an option - now when deleting a domain the whole data path is removed - quite bad!)
