1. Splunk 7 is and has been unsupported for quite some time already so if anything goes wrong you might have problems getting help. This upgrade is several years overdue.

2. See the https://docs.splunk.com/Documentation/Splunk/9.1.1/Installation/HowtoupgradeSplunk document for requirements for specific versions (you can change the version of the document in the top right corner). You can upgrade to 9.x from 8.2 or any lower 9.x. So your first "stop" needs to be 8.2. If you see the document version for a 8.2 release, you see that you firstly have to upgrade to 8.0 or 8.1

So your upgrade path should be 7.x -> 8.0.x or 8.1.x -> 8.2.x -> 9.x

My indexer server is 2016 and splunk 7 is installed there , but somehow OS got crashed , so we have to re-install the OS and after that we will re-install the splunk 7 instance there, and the old Data is present in F Drive as it was configured as such.
so my question is that if i re-install the splunk 7 there and configure it as old version, will the data get reflected in splunk instance?

Ahhhh... So it's not a simple in-place upgrade but rather a restore from a broken installation? (I assume it's an all-in-one instance). It should be doable but it depends on the layout of the original server, on how it was installed, where the configuration was stored and so on. And it's something I'd advise you to go to your friendly local Splunk Partner for help because it's something that requires a bit of experience to do properly and damage your data.
