postdrop: warning: uid=0: File too large sendmail: fatal: root(0): message file too big Error sending message, child exited 75 (Deferred.). Could not send the message.
Be warned installing exim to try and solve the issue will not work and do the following:

MySQL
It is commonly easier to use this to dump and restore MySQL, instead of using mysqldump on the new server via .sql files:
mysqldump --default-character-set=binary --user=root --password=EnterPasswordHere databasename > dbdump.txt
mysql --silent --local --password=EnterPasswordHere DatabaseName < dbdump.txt
Speed up SSH login
By default for some reason in Debian 6 (Squeeze) /etc/ssh/sshd_config does not have UseDNS=no within it. Add it into the file and restart SSH and this will greatly improve SSH login as a sudo user or root. GSSAPIAuthentication=no may also help.
Transmission
The easiest way to get this working is by doing:
vim /etc/apt/sources.list
Add in this line:
deb http://ftp.uk.debian.org/debian sid main
Do apt-get update , then do:
apt-cache show transmission-cli | grep Version apt-cache show transmission-common | grep Version apt-cache show transmission-daemon | grep Version
apt-get install transmission-cli transmission-common transmission-daemon
Then, to edit the files without it overwriting /etc/transmission-daemon/settings.json
Stop the service, edit the file, backup the file and then start the service.
/etc/init.d/transmission-daemon stop vim /etc/transmission-daemon/settings.json cp /etc/transmission-daemon/settings.json /root/settings.json.backup /etc/init.d/transmission-daemon start
Check /etc/transmission-daemon/settings.json is the same file you edited and that it is owned by debian-transmission:debian-transmission
Wordpress
If you are using a Vanilla build of a Unix OS you will need to do this so themes and plugins can install:
cd /var/www/vhosts/
chown www-data:www-data yourdomain.co.uk/* -R
Stop prompting for FTP credentials
echo "" >> /var/www/vhosts/yourdomain.co.uk/wp-config.php
echo "define('FS_METHOD', 'direct');" >> /var/www/vhosts/yourdomain.co.uk/wp-config.php
