Thank you for all reactions. I learned a lot from it.
I took the plunge and first did a minor upgrade from 10.1 to 10.3.
Then the major upgrade to 11.0 (following the handbook).
Initially everything looked fine (website up and running!).
But then some problems came up:
  - different versions op php are installed
  - gkrellmd won't start (libkvm.so.6 not found)
  - (and this is the worst) pkg doesn't work: libssl.so.7 not found
Installed version is pkg-1.10.0_2.
pkg-static info works but still gives the message:
Warning: Major OS version upgrade detected.  Running "pkg-static install 
-f pkg" recommended

During the forced upgrade of all packages I saw that an attempt was made 
to downgrade
pkg to 1.9.something and I also saw that a POST_INSTALL failed for some 
reason.
Any recommendations?
Thanks again for your help!
