Redirect 301 of the old url

ok I have understood but in the event in which the URL they were for example:
joomla.sakic.net/index.php?option=com_co...d=9&id=81&Itemid=145 and not
joomla.sakic.net/content/view/1/2/
the redirect would work the same one?

Non-sef URLs will not redirect. Only old SEF links.

In the Custom component strings I changed from mtree=>business to mtree=>directory
and changed Alias from business to directory

and defined in Redirects:

Source URL: business/
Target URL: directory/
Type: 301 Moved Permanently

How come the old SEF Advanced URLs containing prefix business/ gave me error 404: Not Found instead of replacing them to URLs containing prefix directory/    ???

I have tried to define the full URL but got the same error, eg business/abc.html and directory/abc.html

I have read SEF Advance Help and this Forum, but do not know what I did wrong or what/where else should I define ? I am using version 5.5.5 and any help would be much appreciated.

Defining the full URL correctly should work. It will not work for business/* -> directory/*, every URL needs to be redirected separately. More advanced redirects must be set in .htaccess.

I have removed Redirect definations in SEF Advance and used cPanel > Domains > Redirects tool to define permanently (301) and checked redirects with and without www:

abc.com/business => www.abc.com/directory

Then used FTP to check .htaccess file that has been inserted automatically by cPanel the last 3 lines at the bottom:

DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR]
RewriteCond %{REQUEST_URI} (/|\.htm|\.php|\.html|/[^.]*)$  [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php

RewriteCond %{HTTP_HOST} ^abc.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.abc.com$
RewriteRule ^directory/$ www.abc.com/business/ [R=301,L]

I then used FireFox browser to visit a valid SEF Advance URL, then replaced in the URL the folder name /business/ with /directory/ and pressed enter (and later refresh button), but I still got error 404: Not Found !!

I have tried with the slash / after folder names but got the same error 404:
abc.com/business/ => www.abc.com/directory/

I have also tried with the wildcard * after folder name/ but got the same error 404:
abc.com/business/* => www.abc.com/directory/*

RewriteCond %{HTTP_HOST} ^abc.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.abc.com$
RewriteRule ^directory/?(.*)$ www.abc.com/business/$1 [R=301,L]

Help please !

Sorry the last line in each case should have been as follows but still did not work:

RewriteRule ^business/$ www.abc.com/directory/ [R=301,L]

RewriteRule ^business/?(.*)$ www.abc.com/directory/$1 [R=301,L]
