ZCP 7.0 has some major database changes to realise a higher IO performance and support more concurrent users on a single Zarafa Server.

The largest database architecture changes in the introduction on a new table called tproperties. This table will contain all mapi properties which will be displayed when opening view in the client, for example the calendar week view or the inbox view.

During the upgrade process this table will be filled with all required mapi properties of existing data. In large email environments this process can take some time.

All other mapi properties like bodies, headers are still stored in the properties table.

For upgrading previous Zarafa versions and database conversions, please read the upgrade section of these release notes.
