Apps not showing up after moving server

I have sucsessfuly moved to a new server. I can log in and access files hovever a lot of the apps are not showing up on the drop down (even thought they are enabled).

Apart from moving the database & files is there anything else I need to do? Manual seems to say I only need to move database and files to migraye.

for sure you need to install all apps on the new server as well.

Odd, dont remember doing that before. I am using the sources (for ubuntu). Calinder, contacts app were (am I fairly use) already there. Also the apps are enabled. Can they be enabled with out being installed?
