Problem

A DLO Server with Dedupe is being replaced and needs to be migrated to a new DLO Server.

Solution

1 . Disable all of the Desktop Agents on the old DLO server
  • From the DLO Console, go to Tools -> Options, Global Settings -> Options
  • In the right pane under "Disable", check the box for "All Desktop Agents" and click 'OK'

2. Stop the Veritas (Administration, Maintenance, Edge, Web), Mindtree StoreSmart and SQL Server services on the old DLO server.

3. Make a backup of the DLO.mdf and DLO_log.ldf files from the default path:
<old machine Installed path>\Program Files\veritas\veritas DLO\Data\)
 
4. Make a backup of the dedupedb.mdf and dedupedb_log.ldf files from the default path:
<old machine Installed path>\Program Files\veritas\veritas DLO\Dedupe\Database)  
 
5. Create the same installed path folder structure on the new machine and place the old database files to that path:
<new machine Installed path>\Program Files\veritas\veritas DLO\Data\)
<new machine Installed path>\Program Files\veritas\veritas DLO\Dedupe\Database)  

6. Install the Admin server, Dedupe server, and maintenance server on the new machine (make sure to install to the same directory where the database files were copied to).

7. Open the DLO Console on the new DLO Server:

  • Go to Setup->Dedupe->Edit and provide the IP of the new Dedupe Server and press ok.
  • Go to Setup->Dedupe->Manag e and create the sa me pool and dedupe storage location as there were in old server.​
  • Create the storage location and attach it with the respective dedupe storage location as it is configured in the old server.
8. Copy and paste all of the contents of the NUDF and Dedupe storage from the old server to the new server storage location path with the appropriate security attributes.​
9. Ensure all of the files and folders in the new NUDF and Dedupe folders are identical to the files and folders of the old server.​  
10. On the new server, run the command to assign users to the new storage location.​  ( https://www.veritas.com/docs/HOWTO63842)
For example: DLOCommandu.exe -AssignSL -NI 50 -U *
11. On the old server run ChangeDB command to notify each users to point to the new DB machine. ​
For example: DLOCommandu.exe -ChangeDB -DBServer newmachine -DBInstance DLO 
12. On the old server run ChangeServer command to notify each users to point to the new Server machine.
For example: DLOCommandu.exe -ChangeServer -M machine2 -U *
13. Restart the Mindtree Storesmart, DLO Admin Service and SQL services.​
14. Enable all Desktop Agents.
