Renew lease by using offline mode

The context is for C++ app.
I found some information about offline mode for activating the license.
But is there an offline mode to renew the lease ?
Thanks for your help.

Hi Gilles,

Is your question related to hosted-floating licenses? If yes then they are only meant for online scenarios. In the case of offline floating licenses, you should use LexFloatServer.

In the case of node-locked licenses you just need to repeat the offline activation cycle to sync the server changes with the client.
