best practice for moving scalix to new hardware?

[DohnJoe]

Hi,
I will have to move a scalix installation (community edition 11.04 on centos 4.4) to new hardware (more hd space).
I've found different approaches in the forum and was wondering which one would be recommended.
a) Exporting all IMAP/MAPI/public folders in Outlook, deleting the old profile and creating a new one on the new scalix server and importing the folders again (that's what I did when moving the old exchange4linux installation to scalix).
b) Moving the new scalix installation /var/opt/scalix to /var/opt/scalix.old and rsyncing /var/opt/scalix from the old server onto the new one and restarting the new server ...?
c) Backing up the mailboxes on the old server as per [url]http://www.scalix.com/wiki/index.php?title=HowTos/BackupScript_Mbox_Style[/url]. Moving them to the new server and restoring them following [url]http://www.scalix.com/wiki/index.php?title=HowTos/RestoreMBOXStyle[/url].
Any best practice on how to do this?

Thanks in advance,

Bernhard

I don't think there is such thing as "best practices" when *moving* a scalix installation from one hardware to another. There is only "the practice", which is exactly *move* the installation.

If you have enough knowledge to craft properly the required configuration files for booting, you can just *clone* the smaller drive on the old machine to larger drive on the newer system, and ensure the system boots (you need to know what to put on the /etc/fstab file). From that point on the kernel itself should be able to "self-adjust" to the new HW surroundings at boot up, and all you may have to do is adjust the network ports by hand and the system should be just fine after that.

You could also use some imaging or barebone recover application to do the same thing described above on a more "professional" way.

And yet a more conservative way is to move the /var/opt/scalix from the old server to the new and install scalix over it again, provided that the new server keeps the same FQDN and IP as the old. You could take this chance to do both an OS upgrade as well as a scalix version upgrade. In that case these 2 threads should give you a good general direction:
