[ZendTo] upgrading

[John Cooper]

Hi, upgrading from source 4.06 to 4.10

Is it better to overwrite current directory or move the old one and 
create new, then update the new?

I've used meld to compare all the differences and tested an upgrade and 
seems to be ok creating a new directory.

I'm using mysql so I have imported the sql/zendto.MySQL to the current 
DB to create any new tables.

Is there anything else I need to know about upgrading, like RRD graphs?

Thanks, John.
