Here is tips to upgrade license for Cisco LMS4.1(Ciscoworks). Due to lack of documentation, I spent an hour to figure it out.
1. Download license file *.lic (it comes with *.zip, but unzip it before upload)
2. Upload the file to LMS server on directory " LMS/root-ade hsperfdata_casuser "
* If you put the file on other location, you might have permission or visibility issue.
3. Create "casuser" on local user section thru LMS server portal.
4. Change ownership
ex) LMS# chown casuser:casusers LMS20120111153122885.lic
5. You should see the license file from browing windows.
