Jachym,
Well, I'm finally going to do it this weekend, so I'm on my way to 7
Remember that I'm on 5 now.
My plan is to upload 7 as a fresh upload.
Use the settings for where my MySQL files are and permissions to access.
Make sure the Weather Display upload of the data are still pointed to correctly for the updates (I don't think any of the two above things would change.
Do the settings setup which wasn't in 5, to make sure all the station settings are correct.
Start 7 in it's own space on the server to make sure all is set up well and tweak the positions of the blocks.
Point to 7 when I get it all going alright.
Do you see anything wrong with this plan, to do a fresh install without having to fiddle around with the database, which sort of scares me.

PS, I think that your published intention to bring Meteotemplate up to what your initial vision was is perfect.
I'm sure some very minor new things will come to someone's mind, but so much of what you already offer is above and beyond what I'll implement that to wait awhile for you to carefully and thoughtfully modify your program is well worth the wait.
