Migrate to new server

[skoena]

My server needs to be upgraded to Ubuntu 12.
What are the right steps to "easily" migrate to the new server?
(db's, data, mail, ispconfig etc)

Pffff as a linux noob this is some job.....

For example on the old server I want to copy /var folder (using scp) to the new server keeping file permissions. I tried to copy them but access is denied because only root can copy these files?

I used

scp -rp /var administrator@newserver:/var

Is this command correct?

How can I get root access to the new server to be able to copy the files to the new server?

On Ubuntu, you must enable the root account by setting a root password:

sudo passwd root

Falko,
Did it but when trying to connect I get Permission denied.

ssh root@myip
root@myip's password:
Permission denied, please try again.

Changed "PermitRootLogin yes" in /etc/ssh/sshd_config and restarted ssh

service ssh restart

and it works now!

2nd question.

I want to copy the files from the old server to the new server. How should I do this? I want to keep the permissions and owners like it is on the old server.

There's a saying in Dutch (in my best English translation): I don't see the forrest because of all the trees.
Untill now it's not clear how to do a "good" migration to a new server. Is it an idea to create a sticky about this?

*I copied (with rsync) all the data from
/var/www
/etc
/var/log/ispconfig/httpd
/var/vmail
/var/lib/mysql
(databases were not available on new server when I did this, so I dumped the db's on the old server and copied them to the new server with:

mysqldump --opt --user=root --password=xxxxxxxx --all-databases | gzip > mysql_backup.sql.gz

) For some reason the dbispconfig database was not imported so I imported it by hand via phpmyadmin.

Do I need to copy more or is this enough??
Is there anything I missed?

Till/Falko,
Idea to create write a sticky or howto how to backup a server running ispconfig and restoring it to a new server?

I now try to combine a lot of posts but still not clear what to do and which steps to do.

Can somebody make a post explaining all the steps needed to copy all contents from 1 server to another server? (files, db's, changes to ispconfig files eg passwords etc etc)

Can somebody make a "howto"?

Here the steps:


1) Backup the following directories on the old server: /var/www, /var/vmail and /etc, ensure that you preserve permissions e.g. with "tar pczf backupfile.tar.gz /directory/to/backup".
2) backup all mysql databases.
3) install ispconfig on the new server.
4) backup the new dbispconfig database and empty the database afterwards. Then restore the database of the old server.
5) copy all users and groups of the websites (users are web1, web2, ... , groups are client1, client2, ..., etc.) from the files /etc/passwd, /etc/shadow, /etc/group and /etc/gshadow from the old server to the new server. Copy only the lines of the users and groups, not the whole files! and make a backup of the files before you change them.
6) restore the contents of /var/vmail and /var/www on the new server.
7) restore the databases of the clients
8) Login to ispconfig, go to tools > resync, check all checkboxes and click on start and wait a few minutes to let ispconfig write missing config files.
