=== Moving from SME 7.x to SME 8 ===
 +
 +
{{Note box|Please note this information has not been thoroughly tested but may serve to assist - it worked for me but YMMV.}}
 +
 +
 +
See this thread:
 +
 +
http://forums.contribs.org/index.php/topic,46531.0.html
 +
 +
and this Bug :
 +
 +
http://bugs.contribs.org/show_bug.cgi?id=6195
 +
 +
 +
It would appear that you cannot rename the VolumeGroup on a SME 7 installation with the SME 8 CD
 +
 +
{{Note box|Before you start,  It might be worth fscking the disk/s to ensure that there are no errors.}}
 +
 +
# Make sure you have a very good backup
 +
# signal-event pre-backup on the old installation
 +
# Boot with a SME7 CD and only one of your original disks (in the case of a RAID1 arrangement)
 +
# As per instructions in "Boot from SME Server 7.1 (or newer) install CD" above :
 +
 +
Type "sme rescue" at the command prompt and hit enter
 +
 +
Note: don't start the network and skip mounting the filesystem.
 +
 +
mdadm -AR /dev/md5 /dev/hdx2
 +
lvm vgscan
 +
lvm vgs -v
 +
lvm vgchange -a n
 +
lvm vgrename orig_vg_name new_vg_name
 +
exit
 +
 +
Now remove the CD and reboot into SME 8 :
 +
 +
mdadm -AR /dev/md5 /dev/hdx2
 +
vgscan
 +
vgchange -a y new_vg_name
 +
mkdir /mnt/tmp
 +
mount /dev/new_vg_name/root /mnt/tmp
 +
 +
{{Note box|In some rare cases your VolumeGroup name listed in the last line might be different, more information can be found in [[[[bugzilla: 3883]]]].}}
 +
 +
You should now be able to view all your old data under /mnt/tmp
 +
 +
 +
db configuration setprop backup Program CopyFromDisk status enabled
 +
signal-event pre-restore
 +
signal-event restore-tape /mnt/old (note: this step may take a long time depending on how much data is being restored
 +
signal-event post-upgrade
 +
signal-event reboot
 +
 +
Shutdown and remove old drive and reboot
 +
 +
All the usual warnings apply. Remember that any old contribs & templates will have to be reinstalled (assuming that they will work with V8)
