How to convert to new format

[Sniffierpond]

Hello,
I recently updated llama.cpp and when starting the program it says that I need to convert the models to the new format to use mmap.
It may seem dumb but I actually don't know how to do it. Is there a program or a script to do that or do I need to completely reinstall the models ?
Sorry for my bad English and thank you by advance for your answer.
