FreeRTOS upgrade from version 8.x to 10.x

I am currently using FreeRTOSV8.1.2 in my software stack. I had few concerns.

  1. I want to upgrade to latest stable version. Is V10.3.1 drop-in compatible with FreeRTOSV8.1.2?
  2. If not which is the latest version which is drop-in compatible with FreeRTOSV8.1.2 with least/no migration efforts?

Here is the page that describes updating from 8.x.x to 9.x.x - and likewise for upgrading from 9.x.x to 10.x.x
