Suppose we have a license of 500 GB/day.
we have added a new license file of 750 GB/day.
Why does the total go upto 500 + 750 = 1250 GB/day.
Can two licenses be active at the same time. So, can we index without errors for upto 1250 GB/day ??
Or should we delete the old file
if you buy additional license it makes 1250gb/day .
if you want to upgrade to 750gb it makes 1250gb/day .
You can split it by index etc, check this url for more detail. http://docs.splunk.com/Documentation/Splunk/7.0.3/Admin/Groups,stacks,pools,andotherterminology
If both licenses are valid, the license quota is combined from both licenses. And yes, you can index that combined amount without any error.
