Roger,

Just to close out the thread, I discovered the issue with the transfer of data.

It turns out that the old Calendar module, for whatever reason, was storing the value for the EventDateEnd column as 1 day less than the EventDateBegin column.  I entered a few new entries and saw that the dates were always the same.  So after I imported the events using the Import AVCalendar function of Events 3.3.8 (I also upgraded the suite to 3.3.7), I ran the following script against the database:

update

events set eventdateend = dateadd(day, 1, eventdateend) where eventdateend < eventdatebegin

and all of my events are now showing up.  I did this on my local test backup oif the production site, now I am updating the production site.

Cheers
Dave

I'm in the slow process of upgrading all of my sites to 4.9.0, 3.3.7 is a stepping stone.

Thanks again for chatting and giving me a place to think outloud.  Hopefully this helps someone else.

Cheers

Hi Jill,

As always I would recommend performing an upgrade on a copy of your site first. An upgrade from 3.3.8 to 4.0.2 should be just fine, it is pretty tried and tested. 4.1.x is still not a fully released version, it is still in beta, so we don't recommend for production use yet (in effect at your own risk). Note that 4.1.0 was an early beta, 4.1.2 is the current beta and still has a few bugs including an upgrade bug. So I would suggest you wait a while before moving on from 4.0.2.

Cheers
Roger
