Per the FAQ in the Wiki, only upgrading from one major to the next major
release is supported. Skipping major releases is *not* supported.
Thus for you, 2.6.21 > 3.11 > 4.2 would be okay.
However, 2.6.21 > 4.2 *might* result in issues which *may* include data
loss or corruption. (no guarantees either way) You might get lucky, you
might not. You might not, and not realize it for some time depending on
the nature of the corruption/loss.
Properly upgrading *should* result in custom reports and other settings
being migrated properly. There were some migration issues with the early
3.x series, but that was solved at some point. (not sure of the cutoff
release, see release notes starting with 3.0 till about 3.3 or so if
curious.)
Also per the FAQ and the Wiki, after opening your data file for the
first time with each new major version, you should run Action > Check &
Repair > Check & Repair All to make sure your book is adjusted to
reflect any changes to how GnuCash internally records data. This also
can prevent previous versions from reading the file after this point.
(this will vary by book, according to what features you were using in
the prior edition) The release notes for 3.0 and 4.0 should detail these
changes.

Currently running 2.6.21 (without issues) and think I should probably
upgrade to 4.whatever.
I know I need to bridge via 3.something, but can I safely assume that
3.11 will do the necessary data tweaking, or should I start with an
earlier 3.x? And is opening and closing my files sufficient, or do I
need to take any other actions before further upgrading to 4?
I've looked on the website and the wiki for answers but failed to find them.
