On PS4, the Legacy Console Edition of Minecraft still exists for people who owned it before Bedrock came out, you can launch it from a button on the Bedrock title screen.
In Legacy Console edition it says your worlds are accessible to transferred into the new Bedrock edition, but I can't figure out how to do so.
I know that the ability to transfer worlds from Legacy PS3 edition to Legacy PS4 edition was removed in April 2020. But none of those sources mention the Legacy PS4 -> Bedrock PS4 path being removed, so it should still be available?

I found it. In the Bedrock edition world select menu, just scroll to the bottom and there will be a secondary sublist with the heading "old worlds", which are the legacy console worlds. They can be loaded into bedrock from there.
