@ everyone about a compatible htaccess to upgrade to vb4 without losing google indexed pages:

I't reeeealy easy, use this htaccess:

RewriteEngine on

#First of all, the tfSEO rewrite rules:
#tfseo start here
RewriteRule ^(.*)t([0-9]+)(.*)newpost(.*)$ showthread.php?t=$2&goto=newpost [QSA,L]
RewriteRule ^(.*)f(.*)/(.*)t([0-9]+)(.*)/post([0-9]+)(.*)$ showpost.php?p=$6 [QSA,L]
RewriteRule ^(.*)f(.*)/(.*)t([0-9]+)(.*)/([a-z]+)([0-9]+)(.*)$ showthread.php?t=$4&page=$7 [QSA,L]
RewriteRule ^(.*)f(.*)/(.*)t([0-9]+)(.*)$ showthread.php?t=$4 [QSA,L]
RewriteRule ^(.*)f([0-9]+)/([a-z]+)([0-9]+)(.*)$ forumdisplay.php?f=$2&page=$4 [QSA,L]
RewriteRule ^f([0-9]+)(.*)$ forumdisplay.php?f=$1 [QSA,L]
RewriteRule ^(.*)-f([0-9]+)(.*)$ forumdisplay.php?f=$2 [QSA,L]
#tfseo ends here

#than what follows is the standart vbulletin 4 .htaccess file:

# If you are having problems or are using VirtualDocumentRoot, uncomment this line and set it to your vBulletin directory.
# RewriteBase /forum/

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# Forum
RewriteRule ^threads/.* showthread.php [QSA]
RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]
RewriteRule ^blogs/.* blog.php [QSA]
ReWriteRule ^entries/.* entry.php [QSA]

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# MVC
RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

Make sure that old urls are redirected on new ones, and you are done.

Easy, isn't?
