You only have that, when you do not update SOPE packages too.

Yes, but sogod will create every new user with an old table structure!
Therefore I would suggest against using it with the old SOGo 2.2.16.
Or you need to do the database upgrade again before switching to the new
version.

Beware:
The script is really inefficient.
Therefore it needs some time to run over a lot of users (we have ~18000).
We talk hours here :-)

Disable sogod in order to be sure nobody changes any data.

Take a backup ;-)
Preferable with sogo-tool.

Run the database script.

Start sogod and enjoy.

Should work without problems.
