====== Moving an ISPConfig2 server ======

===== on the OLD server =====

Make a backup of:
  /etc/group
  /etc/passwd
  /etc/shadow
  /etc/apache2/vhosts/Vhosts_ispconfig.conf
  /etc/postfix/local-host-names
  /etc/postfix/virtusertable
  /etc/proftpd*.conf

==== BIND ====

  cd /var/lib/named/etc/bind

Backup BIND files if use DNS
  named.conf
  all the pri.* zone files


==== MySQL ====

Create 3 sql dumps: ALL your MySQL databases
  mysqldump -p --all-databases > all_databases.sql
  mysqldump -p --databases mysql > mysql.sql
  mysqldump -p --databases db_ispconfig > ispconfigdb.sql

"mysqldump" does not dump the **INFORMATION_SCHEMA** database. If you name that database explicitly on the command line, mysqldump silently ignores it.

remember that the **mysql** & **test** databases are specials! You need to remove them from the **all_databases.sql** dump, before import in the new server

To show the databases on your mysql server run
  mysqlshow -p


==== Postfix ====

Create a Postfix transport, so that all emails are forwarded to the new server, until the MX records of your domains have switched to the new server, run:
  echo "*  smtp:[<FQDN or IP address, of new server>]" >> /etc/postfix/transport
  postmap /etc/postfix/transport
  postconf -e 'transport_maps = hash:/etc/postfix/transport'

Stop Postfix so that no new mails can arrive:
  /etc/init.d/postfix stop


==== Apache ====

Backup **/var/www** on the old server
  cd /var
  tar -pczf www.tar.gz www/

Remember that **-p** stands for keep permissions


===== on the NEW server =====

Install ISPConfig, it **MUST BE THE SAME VERSION OF THAT ON THE OLD SERVER**


==== MySQL ====
Regarding the **mysql** database: have a look at the **users** & **db** tables in the **all_databases.sql** dump file, then add the **user** & **db** rowsthat don't exist on the new server but on the old server.

So, completely remove the **mysql** database from the **all_databases.sql** file, then create all the databases running:
  mysql -u root -p < all_databases.sql
  mysql -u root -p < mysql.sql

It is safe to replace the ISPConfig database with the old one


==== ISPConfig ====
Log in to ISPConfig and go to
  Management -> Server -> Settings
and change the IP address(es) there.


==== Postfix ====

Copy **local-host-names** and **virtusertable** to **/etc/postfix**

Open **local-host-names** and replace the old hostname with the new one, add the hostname of the old server at the bottom so that the new server accepts the forwarded mails, then run
  postmap /etc/postfix/virtusertable


==== Apache ====

Replace **Vhosts_ispconfig.conf** with the one from the old server. Open it and replace the old IP address with the new one, then restart apache
  /etc/init.d/apache restart

Transfer www.tar.gz to **/var** and unpack it:
  cd /var
  mv www www_orig
  tar xvfz www.tar.gz


==== ProFTPd ====
Transfer proftp*.conf files, open them and replace the old IP address with the new one
Restart proftpd
  /etc/init.d/proftpd restart
