FlexLM backward compatibility

Hello,

I have 3 questions.

1. My license generator was built with FlexLM 10.1 and client with 11.14.1. I upgraded my client application to FlexLM 11.14.1.3 and it stopped working. It thew LM_BADCODE error which maps to "Bad encryption code". Then I upgraded my license generator application from 11.4.1.3 and everything stated working. So, Is it necessary to upgrade the license generator to use this version of FlexLM?

2. If I upgrade my license generator, will the file generated with upgraded FlexLM be compatible with old client application of FlexLM? Is there any flag to make it backward compatible? It is a tedious process to re-share the license files to customers.

3. I noticed a significant improvement in time taken to checkout the license when I upgraded both license generator(from 10.1 to 11.14.1.3) and client (from 11.14.0.1 to 11.14.1.3). Have you made and performance improvement while transitioning to this version?

Best Regards,

Mohan.

Hi, the rules about FLEXnet Publisher component version compatibility are:

• Version of lmutil/lmtools must be >=

• Version of lmadmin or lmgrd, which must be >=

• Version of vendor daemon, which must be >=

• Version of the client library linked to the FlexEnabled application, which must be >=

• Activation utility, which must be >=

• Version of license file format.
