“ERR LC.V: New license type is not supported prior to 5.3”

You may see the following license error:

2018-10-03 12:50:58.439805 [NOTICE] Memory size is: 8388608KB.
2018-10-03 12:50:58.633518 [ERROR] [LICENSE] License key operation failure: ERR LC.V: New license type is not supported prior to 5.3.

8GB of memory meets the license requirement already. Why still error?

Our new license type not only have RAM requirement but only need LSWS 5.3 as the minimum version to run. If you are still running LSWS 5.2.x or previous version but orderred new license type, you may see the above error. Upgrading LSWS to 5.3 and above should fix the error.
