Answer 1

The directive "AllowOverride None" in httpd.conf will disable parsing of the .htaccess file within the directories specified (in this case /) -- Can you confirm that either of your .htaccess files are in fact being parsed?
If not, does modifying the Directory subsection within your httpd.conf file to:
<Directory />
Options Indexes FollowSymLinks
Allow from all
AllowOverride All
</Directory>
Solve the issue?

Answer 2

I assume 2.0 is the new version of the site. It looks like /2.0/.htaccess is written as though it expects to be in the root folder. Try adding RewriteBase /2.0/ after engine on. You can remove it later when you replace the contents of the root folder with that of 2.0's.
The main problem is your # Handle Front Controller... rule. It'll capture any virtual URLs before they ever get to the 2.0 folder. Try changing it to this:
RewriteRule ^(?!2\.0(?:/|$)) index.php [L]
That will exclude the 2.0 folder from the current site's virtual URLs.
You do still need AllowOverride all as recommended by the other answer, and the directory should be the same as your DocumentRoot, not /.

Answer 3

Add this code inside root->.htaccess file
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
RewriteRule ^(?!2\.0(?:/|$)) index.php [L]
