I am quite happy, because my upgrade went reasonably well, just a few problems. 

The site was a DNN 3.2.2 with SQL2000 and asp.net 1.1 and I went in one go to DNN 4.5.3 with SQL2005 and asp.net 2.

4 upgrade logfiles 3.2.3, 3.3.1 and 4.3.1 all had a message about FK_Files_Folders: The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Files_Folders". and 4.4.0 only said Error: HelpURL.

At first a few things didn't work but after reinstalling and upgrading all the modules the site worked fine. Very handy to have all the core modules ready to install and to have the upgrade indication for installed modules. Beautiful work.

But what doesn't work is the scheduler. If I select timer method in the host settings there is a scheduler timeout exception every 10 minutes in the event viewer. And if i try to see the scheduler I get a Error: Schedule is currently unavailable and in the event viewer a module load exception:  InnerException: Timeout expired.  

Any suggestions are very welcome.

I am wondering what files should I chek to see if all the files the scheduler needs are upgraded properly?

and do all the logfiles during an upgrade have to be empty. In other words should I redo the upgrade and redo it until I get through it without any errors? 

Thanks in anticipation, Sijmen

thanks, that was a quick response.

i looked with websecurestores littleadmin sql2005 tool and the schedule history table has about 21373 entries in it.

hmm i can delete 1 row haven't found yet how to empty a table in this tool.
