According to this link, to test HTTP2 connections using JMeter, a plugin would need to be installed and a new kind of sampler is used.
The problem is that I already have lots of test case set up using the original HTTP request sampler and it seems stupid to convert my test cases to HTTP2 request one by one with all settings the same. Is there a converter for that?
What's more, it seems the current recorder create HTTP request. Is there a way to record HTTP2 request instead?
