Splunk ITSI upgrade

[medavenu]

Hello Team ,

We have a Splunk ITSI version running on 4.7.1 in Splunk Production and the plan is to upgrade to Splunk 4.9.1 in QA and DEV first followed by Splunk Production and I have upgraded to new version 4.9.1 in DEV ,when i am trying to restore the prod and setup in QA restore job is failing so that I can perform the complete Upgrade with KPI and Entity.

I even tried reverting the older version(4.7.1) and tried to restore the configurations in QA but still job is failing where as the backup was working fine so need your suggestions.
