I have been successfully running the lite version of XAMPP. I now want to upgrade so I can use Mercury Mail for testing, as well as adding Perl. I just want to check to see if there is a different method for doing it aside from the one I figured out. I am going to save the httpd-vhosts.conf and php.ini files (I made several changes to them). Then backup the htdocs dir. Then I will delete the XAMPPLITE dir and install the XAMPP version, adding back the httpd-vhosts.conf and php.ini files and the htdoc directory (a few subdirectories actually).
I figured that the httpd-vhosts.conf and php.ini files are the same in the full version so I wouldn't have to make all the changes again. Does this look correct? Any suggestions?
