Introduction:
Sometimes a server needs to be recreated on a higher version keeping the same hostname.
As a result, applications needs to be moved/ reinstalled as well so we are going to explain how to do so for a Dollar Universe node.
Environment:
Dollar Universe installed in a Unix / Linux server.
Instructions:
Here is a brief description of the actions to move a node from server A to server B.


Action on old server A  
- Stop all queues on node and wait until jobs Complete or cancel those Running. 
- Stop Dollar Universe 
- Unregister the node (unims -unregister -login XXX -pwd XXX) 
- Backup Dollar Universe folders containing data and log:
For example: /uniacndata/NSPPHK (data and bin ) and /uniacnlog/NSPPHK (log) by tar command 
- Copy the tar files to the server B or to a shared folder.
- Stop Server or remove it from the network so that the hostname is resolved with server B.


Action on new server B : 
- Install from scratch the node with same company name / node name / ports and folders without registering it to the UVMS.
- Restore the previously backuped tar files containing the data and log folders.
- Register node (unims -register -mshost xxx -msport xxx -login admin -pwd xxx) 
- Start the node
