Actually now that I think of it, all customers get the same database schema
regardless of whether they have any special features or modifications
enabled, so it won't be a problem with the database. The only problem I can
see is keeping records of what version a customer has.

I got a call last week from a customer who bought our software 3 years ago,
its been working fine, but they someone crashed their server, and now they
need us to fix a corrupted database. No problem, but when I saw what
version they had, it was about 8 major versions behind the current shipping
product. This is an exception, but it does happen. Hence knowing how to
handle version upgrades from a situation like this during a software update
is critically important to us.

Thanks for the information on how you do it. We'll see what can be done for
us.
