License File - how know which license to remove from the License server

[kcooper]

we have purchased a number of licenses over the years. The names of the files are pretty much the same except a number was added at the end of the name. (See example 1 below). we need to give 3 - 1 GB licenses to our Information Security group for their own Splunk enterprise environment. How do i know which license i need to remove from the license server? I would like to give the following licenses (see list of some of our files on the Splunk License server below) to them but how do I know which licenses to delete from the license server and which files those would be in the /opt/splunk/etc/license/enterprise directory (example 1 shows a list of files) . We have several other licenses that are 1,024 MB as well so it isn't like there are only 3 - 1 GB licenses.
ANy help is appreciated.

These files are in XML. If you open it with an editor you can identify details like the size of the license (quote, in Bytes) and creation and expiration dates (in epoch time).
