The real tip should say ‘Don’t upgrade without vigorous testing’.

The only way you are reading this is because you are using a RSS reader. You’re currently not seeing this with a web browser. Why? Because I’m now a member of the ‘Worst Practices Club’. I upgraded my Domino Server to 7.0.1 without testing my blog first. Now, when you access my site via http, you get:
Error 500 HTTP Web Server: Lotus Notes Exception – Incorrect data type for operator or @Function: Text expected
I got caught with a regression bug that happens in 7.0.1 that deals with DbColumn DbLookup and a 64KB limit. (Rocky mentions it and references others mentioning it here.)

Rocky mentions that a server side hotfix is available via the standard support channels. There will also be a client fix available soon.

For me, it looks like I’m going to be rolling back my server. I just don’t know when I’ll have time to do it…
