Update:
I have just reattempted the upgrade with the core 2.6.3 files (without adding plugin folders including course formats).
After installation, when I enter a course (which is supposed to use grid or tabtopics) it opens on the 'adding a new forum' page!
The following debugging message is displayed:
Format plugin format_tabtopics is not found. Using default format_singleactivity
