In this mini-howto I will show howto restore a desktop backup to a new server. In stead of using an USB-stick we will transport the backup using SSH (scp or secure copy).
 +
 +
I upgraded form 7.51 -> 8.0 in vmware esxi 4.1 with the following steps. Perhaps it can help someone.

 +
 +
restore smeX in vmware
 +
 +
1. Make backup from original server to desktop
 +
2. install sme8.x from iso in vmware
 +
    - do not use vmx network cards, but use e1000 nic's instead, see http://bugs.contribs.org/show_bug.cgi?id=7197
 +
    - log in via web-management console http://ip/server-manager and change remote acces so you can log in via ssh as root from internal network
 +
3. install vmware tools, see http://wiki.contribs.org/VMware_Tools#SME_Server_8.0_Guest_on_ESXi_4.0_Update_1
 +

4. update packages
 +
- before update set yum straight
 +
check if this is still needed here:
 +
########## see http://forums.contribs.org/index.php/topic,49362.0.html
 +
 +
yum clean all
 +
rpm -Uhv \
 +
http://mirror.canada.pialasse.com/releases/\
 +
/8.0/smeupdates/i386/RPMS/smeserver-yum-2.2.0-20.el5.sme.noarch.rpm
 +
signal-event yum-update
 +
 +
- update
 +
yum update
 +
 +
it will make a list, say Y
 +
wait while downloading lots of stuff & installing
 +
signal-event post-upgrade; signal-event reboot
 +
 +
 +
4. restore with backup
 +
- make a snapshot
 +
- copy sme.tzg to / directory new sme server (for instance form windows desktop with winscp (= cp via ssh) )
 +
- run comnmands below
 +
 +
cd /
 +
signal-event pre-restore
 +
tar -C / -xzvf smeserver.tgz
 +
If you are replacing an original server that is still running,
 +
shut it down before rebooting the new server
 +
 +
/sbin/e-smith/signal-event post-upgrade
 +
/sbin/e-smith/signal-event reboot
 +
 +
After reboot login to admin-console to change IPs to suit network
 +
If you are replacing an original server that is still running, shut it down before rebooting the new server
 +
 +
Save & Reboot
 +
 +
Delete backup file
 +
 +
cd /
 +
rm smeserver.tgz
 +
 +
System should now be online & operational,
 +
Run tests if all works:
 +
- check email (send & retrieve)
 +
- check connections & websites
