Upgrade from 2018 to 2019

[DevOma]

Same db with other version - so the users checked their "Settings=>Context menu" with version 2019? And again - NO context menu or only missing entries in context menu? That makes a huge difference for me...

And startup problems - users should try to run the DataOptimizer (in Administration menu) - this could solve some data issues - if not I would need a sql backup for analyzing - but first the users should try it with the DataOptimizer!
