How do you switch clients?

I'm using the official F-Droid client now but I'd like to switch to another one. The problem is I have some third party repos added and I don't really know how F-Droid works (it seems to have a lot of modules for app installation). I don't want to break it or reflash my whole OS. So can I just uninstall the previous client, install the new one and add the repos back or are there any additional steps I must follow on order for it not to cause any issues?

EDIT: thank you to everyone who replied. I did what was recommended the most (installed 2 clients alongside and deleted the old one after copying all repos and settings) and it seems to be working fine.
