Update ocs server 2.0 to 2.3 db error

I have a database problem when upgrading from version 2.0 to 2.3, after finishing the installation and using my existing database, I can see that the new records are not loaded correctly showing fields like the empty network.
If I do a clean installation with an empty database if the records are loaded correctly but when using the old database there are values ​​that are not loaded.

What are my options?
Update my old database or import the old data to the new database ??

regards
