Upgrading starlte to Android 10 on S9

Thank you for your thoughtful comments and words of encouragement. I’m still struggling to understand whether it is ok for me to upgrade to Q. In your reply to @Manoj you mentioned an inaccuracy that as far as I understand it is known has been reported. I saw mention of this on another post that I can’t seem to locate at this moment. This is the ambiguity I was referring to. Frankly… I don’t know what to believe.

-is going from Starlte 8.1.0 to Android 10/Q going to cause issues?
I can see from here https://doc.e.foundation/devices/starlte/upgrade that there is a note of caution


that makes me aprehensive.
-I also see this guide [HOWTO] Update /e/ that is different
-Do I need to install TWRP? How about about Heimdall?
-Is it correct for me to assume that I don’t need to unlock the bootloader?
