Howto migrate 1.1.8 -> 1.3.8

[marc]

I try to upgrade server on new machines to be prepared for 1.4.

i just made a first try..
after copying database from my 1.1.7 server and supplying patches from 1.3.8 upgrade directory maps and graphs not working. history data is displayed on other pages like latest value but not in my defined screens and graphs pages. on these pages "no data" is displayed instead. well known problem?
