It’s pretty common to have two different IDEs open on the same project. For example QT developers will often have the QT creator as well as VS code open. Developers on Apple‘s platforms almost always keep Xcode open, while they may also have another IDE open alongside it that allows them to work in the project with greater productivity, but still build and profile and do other things that are only available in Xcode.

I had a similar setup at a previous job. Basically, the journey went like:

1. I already used VSCode as my daily driver. 2. Backend team all used IDEA for their Java codebase/had some workflows designed with it in mind. 3. I familiarized myself with IDEA for working on the backend, but used VSCode for the rest of the codebase.

Not OP, but I'm doing the same thing. I spend 95% of my time in IDEA, though. VSC is for Ansible playbooks (because it has a relatively decent extension), and when I need a quick and dirty fix in some other projects (so you don't have to wait five times as long for IDEA to warm up).
