Hi Harshad

Thanks for posting in the Community! To modernize a software means to switch to an up-to-date software instead of using a legacy software/ outdated software.

Lucidchart is a cloud-based diagramming tool that is always growing and updating as a product. It is also a software to consider when replacing or modernizing your legacy system.

I hope this answers your question. If you have any additional questions please feel free to comment below.
