Hi Hemant,
The upgrade path is as follows:
9.3.2 >> 9.4.2.0.9 >> 9.5.2.0.15 >> 9.6.2.0.13 >> 9.7.2.0.9 >> 9.8.2.0.24
All the Image files can be downloaded from the Support site.
Things to do:
- Take Back up of Config at each upgrade step.
- Upgrade using Google Chrome or Firefox.
- Disable Real Time Monitoring if it is enabled. You can disable it from ZD UI, Monitor :: Real Time Monitoring.
Here is a KB article that explains a bit more about the firmware upgrade procedure:
