I am trying to move my website(-s) to a new server. On my old server Magento and Database was on the same box. This Magento installation Serves two Stores.
I bought two new servers one for the DB and one for Magento only. My migration path was:

1. Copy old database and move it to new database server.
2. Change DB settings in app/etc/local.xml.
3. Cleaned up var/cache and var/ sessions.

So far so good. Everything till here works as usual, no errors. So I moved to new Server to install magento:
1. Downloaded Magento, extracted it in root web folder.
2. Copied all(!) files from old webserver and put it in the new.
3. Changed permissions to:

chown web37:client1 * -R
chown web37
:client1 .htaccess
. -type d -exec chmod 755 {} \\;
find . -type f -exec chmod 644 {} \\;
chmod -R o+w media var
chmod o+w app/etc
chmod 777 includes includes
-rf var/cache/*
rm -rf var/session/*/
/tempend ?>
4. Changed in .htaccess from
Options +FollowSymLinks
Options FollowSymLinks
#RewriteBase /magento/
RewriteBase /

5. Added

AcceptPathInfo on
to Apache

this configuration gives back the

dbModel read resource does not implement Zend_Db_Adapter_Abstract
with the trace

If change the permissions to 777 of the var folder the server tells me it had a 500 error but i can see absolutely nothing about this error in the error logs although if i change the Apache log level to \"LogLevel debug\” :( Same if i delete or rename the cache folder. Nothing helps and i don’t really know what can i do next. I have tried many many times to reinstall and I’m working to solve the problem nearly since one week. Any help would be nice :(

- If I trying a fresh install everything works fine
- A new Install after remove the old local.xml file wants that some folders in 777, but breaks at next step (after the database initialising) in 500 error.
- Both Server have the Magento requirements, both local.xml\’s are identical.
- Old Magento Server:
CentOS 5.9
H-Sphere 3.6.1
Magento Community

- New Magento Server:
CentOS 6.4
