Here the steps i followed to migrate from 5.0 OS 2003 to 5.2.1 OS 2008 R2 without no issues, this should work for 2012 as well.
======================================================================================================================
- Capture and save the license from the current install:
C:\>dfm license list
Feature License Code Serial # Expiration
---------------- -------------- ----------- -----------
core ************** 1-50-****** ***********
2. Run these commands:
dfm service stop
dfm service start sql
dfm backup create -v <---> ****** very important that you use -v here ******
*If this completes successfully it will provide the full path and filename of the backup*
*If this fails, let us know as we'll need to fix this before moving forward.*
- Disable monitoring and purge controllers and vFilers no longer existent or monitored:
dfm option set discoverEnabled=No
Linux: for i in `dfm host list -a | grep -i yes | awk '{print $1}'`;do dfm host delete -f $i;done
Windows: for /f "tokens=1" %i in ('"dfm host list -a | findstr /I "yes""') do dfm host delete -f %i | echo HostID=%i
- Take another backup.
dfm backup create -v
*If this completes successfully it will provide the full path and filename of the backup*
*If this fails, let us know as we'll need to fix this before moving forward.*
- Move the last backup to a safe location. It should be a place in which the new server can access it in order to restore the DFM db.
- Now Go to the New Windows server and install UM 5.2.1
- Install UM 5.2.1:
Windows - http://mysupport.netapp.com/NOW/download/software/occore_win/5.2.1/
Linux - http://mysupport.netapp.com/NOW/download/software/occore_lin/5.2.1/
- Restore the backup
dfm backup restore <path>\<file>
The restore will take an unknown amount of time due to the database cleanup included in the process.
