Hi..
We are planning for a upgrade from splunk 4.3.2 to splunk6 , for the current splunk 4.3.2 is installed on the below mount point
i.e splunk 4.3.2 mount point : /opt/splunk
splunk 4.3.2 db mount point : /opt/splunk/var
Now we are planning to install splunk6 in different mount point say , /opt/splunk6 and share the common db as splunk 4.3.2 . Now we are planning shutdown 4.3.2 and start splunk6. Lets say something gone wrong , and we wanted to rollback to splunk 4.3.2 , then in this case if we turn off splunk6 and enable splunk4.3.2 , will the database works without fail ? or we will loose data ?? i.e splunk 4.3.2 again supports the Splunk 6 database stuff??
Thanks in advance.
I don't have a definitive answer, but this seems like a risky idea to me.
There are certainly some differences between the 4.3.2 index files and the 6.0 index files. I don't know whether the differences would be catastrophic for a down rev from 6.0 to 4.3.2, but I wouldn't want to be the admin responsible. I don't know of anyone else who has actually done this, either.
Instead, I think you should build a 6.0 test environment and investigate it thoroughly with your data. If it works well, then I would take a backup of production and upgrade to 6.0 - without any expectation of being able to rollback to 4.3.2...
Hi .Thanks for the update ..One more thing, if i copy the db of splunk 4.3.2 in to db path of splunk 6 , will it work without any problem ?
Usual caveats about data backup, etc, apply.
I've upgraded from 4.3 straight to 6; I didn't have any issues.
