Hi,
If you only purchase 100 terminal licenses, then installed in the RD Licensing servers, you only can install 50 CALs in each one or install totally 100 CALs in only one. The time of CALs installation, the installation wizard does not limit the numbers you entered,
but you need to comply with the number of licenses you have purchased.
In my experience , you cannot splitting up the licenses or change the date so that you can splitting licenses. if you want to splitting up licenses, you may rebuild the RD licensing server database.

In each of these cases, you must call the Microsoft Clearinghouse to reinstall the appropriate CALs. For information about how to call the Clearinghouse, see
Locate the Microsoft Clearinghouse telephone number for your country or region.
Additional information:
You have installed two RD licensing server, according to my understanding, you may need RD licensing server sake of redundancy, if your concern is that the time your license server is down, your client is not denied of connection, then you can have a license
server on which you don't have any CALs installed and point your TS to that new license server for the time being. Your clients will keep on getting the temp CALs till the time your new license server is inside grace period. In that time frame, you can recover
your old license server.
If your concern is to have a backup server for the existing one, then you can't have one until your main license server is running. But you have the option of migrating the CAL Packs from one server to other (even if your Source Server is dead).
For that you should have the license server ID of the Source license server and all the paper work related to the license key packs. Once you have that, you can easily recover your dead license server also.
The steps you need to follow for migration of your CAL packs are:
