Migrate images manually
This describes how to manually migrate all images to a new server.

Make sure your image directory on the destination server has the hidden marker files:
touch /images/.mntcheck /images/dev/.mntcheck
Below are many options for migrating all images. This article assumes you have FOG installed already on the new server, because the installer would setup FTP and NFS for you. Fog doesn't setup Samba but an example of how to use a Samba share is included. Where you see x.x.x.x, this is the old storage node's IP address. These commands are written to be run on the new storage node, however they can be altered to run on the old storage node.
lftp -c 'open x.x.x.x; user UserGoesHere PasswordHere; mirror -e /images/TheImagePath /images/TheImagePath; quit'
lftp -c 'open 10.0.0.4; user fog MyAwesomePassword; mirror -e /images /images; quit'
mount x.x.x.x:/<remote source> <local mount point> cp -R /<local mount point>/* /<local destination> umount <local mount point>
mkdir /tempMount mount 10.0.0.4:/images /tempMount cp -R /tempMount/* /images umount /tempMount
mkdir /LocalMountPointHere mount -t cifs //x.x.x.x/ShareNameGoesHere /LocalMountPointHere -o username=YourUsernameGoesHere -o password=YourPasswordGoesHere,noexec cp -r /LocalMountPointHere/* /DestinationHere umount /LocalMountPointHere
mkdir /tempMount mount -t cifs //10.0.0.4/images /tempMount -o username=root -o password=MyAwesomePassword,noexec cp -r /tempMount/* /images umount /tempMount
scp -r firstname.lastname@example.org:/images/* /images
scp -r email@example.com:/images/* /images
Enabling ssh root access on Ubuntu/Debian
apt-get install openssh-server -y
Then adjust the ssh config file to allow root to log in. The configuration file is located at /etc/ssh/sshd_config Change the line "PermitRootLogin" to be yes instead of whatever the default is. The line should look like this when you're done: PermitRootLogin yes Use the text editor of your choice to do it. I like to use Vi.
Instructions on using VI: Vi
Then you should enable and restart sshd, follow steps below.
systemctl enable sshd systemctl restart sshd
You should now be able to ssh and SCP to and from your Ubuntu/Debian box.
rsync -a firstname.lastname@example.org:/images/* /images
rsync -a email@example.com:/images* /images
Image definitions are what's stored in the database, and what is displayed in the web interface. There are DB entries for each image. Image definitions do not automatically appear just because the image files are present on the storage node, this is a common misconception.
You may recreate these manually, but you must recreate them exactly as they were on the old server. The image path must be exact and is case sensitive, the image OS and image type must be set exactly as in the old server as well.
The easiest option is to use FOG's export/import feature inside of Image Management.
