Hi,
Yes you can upgrade from 2.2 to 3.11.3
The steps for upgrade are there on lots of blogs and sites.
You can follow:

You should read the NEWS.txt for information on any release while planning
for upgrade.

Hello,
If we are upgrading from version 2.2 to 3.x, should we go directly to
latest version 3.11.3?
Anything we need to look out for? If anyone can point to an upgrade
process that would be great!
Hello,
The error might be related to your specific clusters (sstableloader / 1
node), I imagine connectivity might be wrong or the data not be loaded
properly for some reason. The data has to be available (nodes up - and
maybe 'nodetool refresh'/'cassandra restart' after the sstableloader things)
Hi Maik,
IMO, when using TWCS, you had better not run repair. The behaviour of TWCS is
same with STCS for repair when merging sstables and the result is leaving
sstables spanning multiple time buckets, but maybe I'm wrong. In my use case, I
don't do repair with table using TWCS.
