Webs offline after migration (Apache shutdown)

[M:ke]

The migration seems to be sucessful, but the apache shuts down after migration.
Problem: Domain directory not found or old configuration used. Take a look in /var/log/apache2/error_log

[Thu Jun 18 12:24:06 2009] [notice] Graceful restart requested, doing restart
httpd2-prefork: Syntax error on line 178 of /etc/apache2/httpd.conf: Syntax error on line 71 of /etc/apache2/default-server.conf: Syntax error on line 355 of /etc/apache2/conf.d/zz010_psa_httpd.conf: Syntax error on line 60 of /srv/www/vhosts/migrated-domain.tld/conf/httpd.include: Could not open configuration file /home/httpd/vhosts/migrated-domain.tld/conf/vhost_ssl.conf: No such file or directory

Solution: Deactivate the domain, restart apache and reactivate the domain.
If you have futher problems, you can check the configuration manually.

apache2ctl -t
